High adherence to the French dietary guidelines decreases type 2 diabetes risk in females through pathways of obesity markers: Evidence from the E3N-EPIC prospective cohort study. Nutrition 2024; 124:112448. [PMID: 38677250 DOI: 10.1016/j.nut.2024.112448] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 01/20/2024] [Accepted: 03/29/2024] [Indexed: 04/29/2024]
Abstract
OBJECTIVE Obesity and type 2 diabetes (T2D) have been associated with low adherence to the 2017 French food-based dietary guidelines, as assessed by the Programme National Nutrition Santé - guidelines score 2 (PNNS-GS2). Whether the association between T2D and PNNS-GS2 is direct or mediated by obesity has been little investigated. RESEARCH METHODS The study included 71,450 women from the E3N-EPIC cohort, mean age of 52.9 y (SD 6.7). The simplified PNNS-GS2 was derived via food history questionnaire. Multivariable Cox regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of T2D. Causal mediation analyses were used to decompose the total effect of sPNNS-GS2 on T2D into a direct effect and indirect effect mediated by body mass index (BMI) or the waist-hip ratio (WHR). RESULTS During a mean follow-up of 19 y, 3679 incident T2D cases were identified and validated. There was a linear association between adherence to sPNNS-GS2 and T2D (P-nonlinearity = 0.92). In the fully adjusted model, each 1-SD increase in the sPNNS-GS2 was associated with a lower T2D risk [HR (95% CI), 0.92 (0.89, 0.95)]. The overall associations were mainly explained by sPNNS-GS2-associated excess weight, with BMI and WHR mediating 52% and 58% of the associations, respectively. CONCLUSIONS Higher adherence to French food-based dietary guidelines was associated with a lower risk of T2D in women, and a significant portion of this effect could be attributed to excess weight measured by BMI or WHR. This finding helps better understand the mechanisms underlying the diet-T2D association.

Predictive machine learning models for ascending aortic dilatation in patients with bicuspid and tricuspid aortic valves undergoing cardiothoracic surgery: a prospective, single-centre and observational study. BMJ Open 2024; 14:e067977. [PMID: 38508639 PMCID: PMC10961501 DOI: 10.1136/bmjopen-2022-067977] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Accepted: 02/14/2024] [Indexed: 03/22/2024] Open
Abstract
OBJECTIVES The objective of this study was to develop clinical classifiers aiming to identify prevalent ascending aortic dilatation in patients with bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV). DESIGN AND SETTING A prospective, single-centre and observational cohort. PARTICIPANTS The study involved 543 BAV and 491 TAV patients with aortic valve disease and/or ascending aortic dilatation, excluding those with coronary artery disease, undergoing cardiothoracic surgery at the Karolinska University Hospital (Sweden). MAIN OUTCOME MEASURES Predictors of high risk of ascending aortic dilatation (defined as ascending aorta with a diameter above 40 mm) were identified through the application of machine learning algorithms and classic logistic regression models. EXPOSURES Comprehensive multidimensional data, including valve morphology, clinical information, family history of cardiovascular diseases, prevalent diseases, demographic details, lifestyle factors, and medication. RESULTS BAV patients, with an average age of 60.4±12.4 years, showed a higher frequency of aortic dilatation (45.3%) compared with TAV patients, who had an average age of 70.4±9.1 years (28.9% dilatation, p <0.001). Aneurysm prediction models for TAV patients exhibited mean area under the receiver-operating-characteristic curve (AUC) values above 0.8, with the absence of aortic stenosis being the primary predictor, followed by diabetes and high-sensitivity C reactive protein. Conversely, prediction models for BAV patients resulted in AUC values between 0.5 and 0.55, indicating low usefulness for predicting aortic dilatation. Classification results remained consistent across all machine learning algorithms and classic logistic regression models. CONCLUSION AND RECOMMENDATION Cardiovascular risk profiles appear to be more predictive of aortopathy in TAV patients than in patients with BAV. This adds evidence to the fact that BAV-associated and TAV-associated aortopathy involves different pathways to aneurysm formation and highlights the need for specific aneurysm preventions in these patients. Further, our results highlight that machine learning approaches do not outperform classical prediction methods in addressing complex interactions and non-linear relations between variables.

Abstract
OBJECTIVE American Indians and Alaska Natives (AI/ANs) are an understudied population at high risk for cardiovascular diseases (CVDs); little is known about contextual factors contributing to CVDs in AI/ANs. This study examined the association of Life's Simple 7 (LS7) factors and social determinants of health (SDH) with CVD outcomes in a nationally representative sample of AI/ANs. METHODS We conducted a cross-sectional study of 8497 AI/ANs using 2017 Behavioural Risk Factor Surveillance Survey data. Individual LS7 factors were summarised as ideal and poor levels. Coronary heart disease, myocardial infarction and stroke were defined as CVD outcomes. Healthcare access measures represented SDH. Logistic regression analyses examined associations of LS7 factors and SDH with CVD outcomes. Population attributable fractions (PAFs) quantified individual contributions of LS7 factors to CVD outcomes. RESULTS N=1,297 (15%) participants with CVD outcomes were identified. Smoking, physical inactivity, diabetes, hypertension and hyperlipidaemia were LS7 factors associated with CVD outcomes. Hypertension was the largest contributor to CVD (aPAF 42%; 95% CI 37% to 51%), followed by hyperlipidaemia (aPAF 27%; 95% CI 17% to 36%) and diabetes (aPAF 18%; 95% CI 7% to 23%). Compared with individuals with poor LS7 levels, participants with ideal levels showed 80% lower odds of CVD outcomes (aOR 0.20; 95% CI 0.16 to 0.25). Access to health insurance (aOR 1.43, 95% CI 1.08 to 1.89) and a regular care provider (aOR 1.47, 95% CI 1.24 to 1.76) were associated with CVD outcomes. CONCLUSIONS Effective interventions are needed to address SDH and attain ideal LS7 factors to improve cardiovascular health among AI/ANs.

Time trends in infectious and chronic disease consultations in Dakar, Senegal: Impact of COVID-19 sanitary measures. J Glob Health 2023; 13:06007. [PMID: 36995306 PMCID: PMC10062398 DOI: 10.7189/jogh.13.06007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 03/31/2023] Open
Abstract
Background The impact of COVID-19 sanitary measures on the time trends in infectious and chronic disease consultations in Sub-Saharan Africa remains unknown. Methods We conducted a cohort study on all emergency medical consultations from January 2016 to July 2020, from SOS Medecins in Dakar, Senegal. The consultation records provided basic demographic information such as age, ethnicity (Senegalese or Caucasian), and sex as well as the principal diagnosis using an ICD-10 classification ("infectious", "chronic", and "other"). We first investigated how the pattern in emergency consultation differed from March to July 2020 compared to previous years. Then, we examined any potential racial/ethnic disparities in COVID-19 consultation. Results We obtained data on emergency medical consultations from 53 583 patients of all ethnic origins. The mean age of patients was 37.0 (standard deviation (SD) = 25.2) and 30.3 (SD = 21.7) in 2016-2019 and 45.5 (SD = 24.7) and 39.5 (SD = 23.3) in 2020 for Senegalese and Caucasian patients, respectively. The type of consultations between January and July were similar from 2016 to 2019; however, in 2020, there was a drop in the number of infectious disease consultations, particularly from April to May 2020, when sanitary measures for COVID-19 were applied (average of 366.5 and 358.2 in 2016-1019 and 133.0 and 125.0 in 2020). The prevalence of chronic conditions remained steady during the same period (average of 381.0 and 394.7 in 2016-2019 and 373.0 and 367.0 in 2020). In a multivariate analysis adjusted for age and sex, infectious disease consultations were significantly more likely to occur in 2016-2019 compared to 2020 (2016 odds ratio (OR) = 2.39, 2017 OR = 2.74, 2018 OR = 2.39, 2019 OR = 2.01). Furthermore, the trend in the number of infectious and chronic consultations was similar among Senegalese and Caucasian groups, indicating no disparities among those seeking treatment. Conclusions During the implementation of COVID-19 sanitary measures, infectious disease rates dropped as chronic disease rates remained stagnant in Dakar. We observed no racial/ethnic disparities among the infectious and chronic consultations.

Abstract
Background:
Diabetes is a major cardiovascular disease (CVD) risk factor. There has been a epidemiological shift and chronic CVD is increasing in Sub-Saharan Africa, however, the extent is unknown.
Methods:
Data were collected between March and April 2013 from 3 regions of the Northern Senegal (i.e., Saint-Louis, Matam etand Louga) using a cluster sampling method and the survey base of the national statistical and demographical agency, we included subjects aged between 18 and 80 years old. Participants underwent a face-to-face questionnaire to collect demographics and data on cardiovascular history/risk factors. Blood pressure and anthropometric measurements were measured in addition to blood tests including fasting plasma glucose. Diabetes was defined as fasting plasma glucose >= 1.26 g/L. Continuous data were reported as mean ± standard deviation (SD). Comparisons used the chi-squared test for categorical variables and Student’s
t
test for continuous variables. Multivariable adjusted logistic regression was used to identify factors associated with diabetes. Covariates with significant association (P<0.05) in univariate analysis were included in the model.
Results:
Among the 2440 subjects in this study (mean age: 44 years old, SD: 15.99), 692 (28%) were male. Nearly half of the sample never attended school (48%, 95%CI: 46-50%). Body mass index (BMI) higher than 25 was present in 43% of the sample (95%CI: 29-35%), with a significant increase in women (51% vs 22%, p<0,001).. The prevalence of diabetes was 5.9% (95%CI: 5-6,9%). Among them, 93% had at least two cardiovascular diseases (95% CI: 87-96%), 71% had dyslipidemia (95%CI: 63-78%) and 67% had a BMI over 25 (95%CI: 58-74%).
Conclusion:
This community-based study revealed a low prevalence of diabetes. However, the prevalence of additional CVD risk factors in this population was high. Preventive measures should be implemented to avoid increasing rates of diabetes in Sub-Saharan Africa.

Abstract
Background:
Recently, a dietary index reflecting adherence to the 2017 French food-based dietary guidelines, the
Programme National Nutrition Santé
- guidelines score 2 (PNNS-GS2), has been developed, but evidence on its level of adherence and incident type 2 diabetes (T2D) risk is limited.
Objective:
We aimed to investigate the association between adherence to the simplified PNNS-GS2 (sPNNS-GS2) and the risk of incident T2D in a French cohort of women.
Methods:
Between 1993 and 2014, 71,450 women aged over 18 years were examined, and thereafter followed up for the occurrence of T2D within the E3N-EPIC prospective cohort. Dietary data were collected at baseline via a food frequency questionnaire, and the sPNNS-GS2 was derived for each participant. Multivariable Cox regression models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) of T2D for continuous and quintile groups of the sPNNS-GS2. Effect modification by body mass index (BMI) and mediation by BMI and waist-hip ratio (WHR) were explored.
Results:
The mean age was 52.9 years (SD 6.7). During a mean follow-up of 19 years, 3679 incident T2D cases were identified and validated. There was a linear association between adherence to sPNNS-GS2 and T2D risk (P
non-linear
= 0.85). In the fully adjusted model, each 1-SD increase in the sPNNS-GS2 was associated with a 8% decrease risk of T2D [HR (95% CI), 0.92 (0.89, 0.95)]. Compared to those with the lowest adherence (first quintile), the third [HR (95% CI), 0.91 (0.82, 1.00)] up to the fifth quintile group [HR (95% CI), 0.79 (0.71, 0.88)] had a lower T2D risk. There was a sPNNS-GS2 x BMI interaction on T2D risk (P
interaction <
0.01) but not with WHR. The overall association was partly mediated by BMI (18%) and WHR (59%).
Conclusion:
Higher adherence to the 2017 French food-based dietary guidelines was associated with a lower risk of T2D in women. Furthermore, our mediation analysis suggests that the lower risk of T2D in women associated with adherence to the sPNNS-GS2 is partly mediated by obesity measured by BMI or WHR.

Abstract
Background:
Patients with renal failure have a higher risk or cardiovascular events. However, the prevalence of renal failure in Sub Saharan Africa communities remain poorly documented.
Methods:
Data were collected between March and April 2013 from 3 regions of the Northern Senegal (i.e., Saint-Louis, Matam et and Louga) using a cluster sampling method and the survey base of the national statistical and demographical agency subjects aged between 18 and 80 years. However, the present study focused on adult populations below 40 years of age. Participants underwent a face-to-face questionnaire to collect demographics and data on cardiovascular history/risk factors. Blood pressure and anthropometric measurements were performed in addition to blood tests including plasma creatinine. Renal failure was defined as a GFR < 60 ml/min/1.73 m
2
using the MDRD method adapted to the African population. Continuous data were reported as mean ± standard deviation (SD). Comparisons used the χ2 test for categorical variables and Student’s
t
test for continuous variables. Multiple logistic regression was used to identify factors associated with CFI, after considering potential confounders. Covariates with significant association (P<0.05) in univariate analysis were included in the multivariate logistic model.
Results:
Among the 2440 subjects in this study the mean age was 44 ± 15.99, 692 (28%) were male. Among the 1080 participants who were aged less than 40 years old (mean: 31 ± 7.54), 296 (27.4%) were male. Body mass index higher than 25 was present in 32% of the studied population with a significant increase in women (38% vs 15%, p<0,001). The prevalence of hypertension was 28%. The prevalence of renal failure was 3.1% (95%CI: 2.1-4.3%) with a mean glomerular filtration rate of 55 ± 23.58. None of the participants with renal failure had diabetes.
Conclusion:
This community-based cross-sectional study showed a low prevalence of renal failure in younger participants in Northern Senegal. Further investigations are needed to assess chronic kidney failure and its determinants.

Abstract
Background:
Primordial prevention is an important way towards reducing risk of stroke with its associated health and economic burdens. So far, no study has shown how the recently updated American Heart Association’s cardiovascular health metrics, Life’s Essential 8 (LE8), relates to stroke events. Therefore, we sought to examine the association between LE8 and the risk of stroke among Finnish men.
Methods:
We employed the population-based Kuopio Ischaemic Heart Disease Risk Factor Study (KIHD) comprising men, aged 42 to 60 years, without pre-existing history of stroke at baseline. The LE8 was computed for 2614 men using AHA’s recently updated metrics. The LE8 includes four health behaviours (diet, physical activity, nicotine exposure, and sleep health) and four health factors (BMI, blood lipids, blood glucose and blood pressure). Each factor had points ranging from 0 to 100. Participants were classified into quartiles based on LE8 scores - Q1, ≤ 420; Q2, >420 to 485; Q3, >485 to 550; Q4, >550. Multivariable Cox regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of LE8 scores for stroke event.
Results:
During a median follow-up of 26 years, 446 stroke events were recorded. The higher the LE8 scores, the more protection from future risk of stroke event. Thus, per quartile increase was associated with 26% lower risk of stroke (HR:0.74; 95%CI:0.68-0.82). Men within the 4
th
quartile (Q4) of LE8 score had the highest protection (65%) from risk of stroke when compared with those within the 1
st
quartile (Q1) (HR: 0.45; 95%CI:0.34-0.60).
Conclusion:
Life’s Essential 8 was strongly and inversely associated with the risk of stroke among middle-aged and ageing Finnish men. Measures that promote LE8 should be encouraged among the general population in Finland.

Abstract
AIMS This study aimed to examine the association between cardiovascular health (CVH) metrics and the risk of heart failure (HF) in a Finnish population. METHODS AND RESULTS We used the prospective population-based Kuopio Ischaemic Heart Disease cohort study comprising men aged 42-60 years at baseline (1984-89) and women aged 53-73 years at baseline (1998-2001). The CVH scores were computed from American Heart Association's CVH metrics for 2385 men and 825 women without a history of HF at baseline. The CVH scores, ranging from 0 to 14, were categorized into three: inadequate, average, and optimal groups. Multivariable Cox regression models were used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) for HF. During a median follow-up period of 27 years for men, and 18 years for women, 465 and 124 HF events were recorded, respectively. The mean ages for men and women were 53 and 63 years, respectively. One hundred and thirty-three men (5.6%) and 73 women (8.8%) had five or more ideal CVH metrics. Participants with optimal CVH scores had a 64% and 48% lower risk of HF when compared with those with inadequate CVH scores among men and women, respectively (HR, 95% CI: men = 0.36, 0.26-0.49, P < 0.01; women = 0.52, 0.31-0.89, P = 0.02). CONCLUSIONS Optimal CVH metrics is associated with a lower risk of HF among an ageing Finnish population. Optimal CVH score should be targeted among the general population to reduce the risk of HF.

Abstract
The African region is experiencing an epidemic of cardiovascular disease with dire consequences of increasing morbidity and mortality. Compared with high-income countries where older populations are most affected, the burden of CVD in Africa is higher in the younger populations, which hampers regional socioeconomic development. Strategies to increase and advance the cardiovascular workforce are urgently needed to help address this problem. This commentary highlights the critical lack of skilled cardiovascular healthcare professionals, including cardiologists, cardiac surgeons, and cardiovascular nurses in the African region. Multilevel viable solutions to advance the cardiovascular workforce in Africa based on successful models in Africa are also presented.

Abstract
Abstract
Background
Cardiovascular disease (CVD) is a major cause of death worldwide. At least two-third of CVD death occurs in low- (LIC) and middle-income (MIC) countries. An estimated 1 million deaths were attributable to CVD in sub-Saharan Africa (SSA) alone. Scarce data are available about the admission for CVD and outcome in cardiology department in SSA.
Purpose
To describe admission for CVD and outcome of hospitalization in 17 in SSA countries.
Methods
We conducted a transversal and longitudinal study in CV department of 37 hospitals from 23 cities in 17 SSA countries (10 low income: Niger, Guinea, Benin, Mali, Democratic Republic of the Congo, Tchad, Burkina Faso, Togo, Burundi, Ethiopia and 7 middle income: Cote d'Ivoire, Senegal, Cameroon, Congo, Soudan, Mauritania, Gabon). The February study was designed by a multidisciplinary collaborative team of epidemiologists, pharmacists and cardiologists from Africa and France. This ongoing observatory included all inpatients in February from each year since 2016.Data including socio-demographic and clinical characteristics, causes of admission, clinical, biological, complementary examinations, treatments, length of stay and discharge diagnosis were collected by the investigating physicians. All analyses were performed through scripts developed in the R software (4.0.3 (2020-10-10))
Results
Overall, 4360 patients were included in the February study. Men represented 56.4%. Mean of age was 56.7±16.8 years. The main cause of admission was heart failure (41.5%) followed by acute coronary syndrome (11.9%) and stroke (11%). Cause of admission varied significantly across countries (p<0.01) and over the years (p<0.01). Proportions of admission for heart failure varied from 20% in Ethiopia to 62% in Guinea. Mean of length of stay was 9.95±22.4 days. All causes of admission confounded, in-hospital mortality rate was 11% (N=423). Mortality rate differed significantly according to causes of admission (p<0.01).Mortality rate among patients admitted for stroke, heart failure and acute coronary syndrome was respectively 18%, 12.3% and 9.5%. Overall, 31 (0.7%) were admitted for endocarditis and mortality rate among them was 20.8% (figure). Overall, mortality rate did not vary according to gender or over the years but was significantly different according to patient wealth index (p<0.05), countries (p<0.01) and level income countries (p<0.01). Mortality rate was significantly higher in LIC.
Conclusion
Heart failure, acute coronary syndrome and stroke represent the two-third of causes of admission. Overall, mortality rate in cardiology departments in SSA reached 11%.

Abstract
BACKGROUND Maintaining blood pressure (BP) control over time may contribute to lower risk for cardiovascular disease (CVD) among individuals who are taking antihypertensive medication. METHODS The Jackson Heart Study (JHS) enrolled 5,306 African-American adults ≥21 years of age and was used to determine the proportion of African Americans that maintain persistent BP control, identify factors associated with persistent BP control, and determine the association of persistent BP control with CVD events. This analysis included 1,604 participants who were taking antihypertensive medication at Visit 1 and had BP data at Visits 1 (2000-2004), 2 (2005-2008), and 3 (2009-2013). Persistent BP control was defined as systolic BP <140 mm Hg and diastolic BP <90 mm Hg at all three visits. CVD events were assessed from Visit 3 through December 31, 2016. Hazard ratios (HR) for the association of persistent BP control with CVD outcomes were adjusted for age, sex, systolic BP, smoking, diabetes, and total and high-density lipoprotein cholesterol at Visit 3. RESULTS At Visit 1, 1,226 of 1,604 participants (76.4%) with hypertension had controlled BP. Overall, 48.9% of participants taking antihypertensive medication at Visit 1 had persistent BP control. After multivariable adjustment for demographic, socioeconomic, clinical, behavioral, and psychosocial factors, and access-to-care, participants were more likely to have persistent BP control if they were <65 years of age, women, had family income ≥$25,000 at each visit, and visited a health professional in the year prior to each visit. The multivariable adjusted HR (95% confidence interval) comparing participants with versus without persistent BP control was 0.71 (0.46-1.10) for CVD, 0.68 (0.34-1.34) for coronary heart disease, 0.65 (0.27-1.52) for stroke, and 0.55 (0.33-0.90) for heart failure. CONCLUSION Less than half of JHS participants taking antihypertensive medication had persistent BP control, putting them at increased risk for heart failure.

Abstract
Background Social isolation, the relative absence of or infrequency of contact with different types of social relationships, and loneliness (perceived isolation) are associated with adverse health outcomes. Objective To review observational and intervention research that examines the impact of social isolation and loneliness on cardiovascular and brain health and discuss proposed mechanisms for observed associations. Methods We conducted a systematic scoping review of available research. We searched 4 databases, PubMed, PsycInfo, Cumulative Index of Nursing and Allied Health, and Scopus. Findings Evidence is most consistent for a direct association between social isolation, loneliness, and coronary heart disease and stroke mortality. However, data on the association between social isolation and loneliness with heart failure, dementia, and cognitive impairment are sparse and less robust. Few studies have empirically tested mediating pathways between social isolation, loneliness, and cardiovascular and brain health outcomes using appropriate methods for explanatory analyses. Notably, the effect estimates are small, and there may be unmeasured confounders of the associations. Research in groups that may be at higher risk or more vulnerable to the effects of social isolation is limited. We did not find any intervention studies that sought to reduce the adverse impact of social isolation or loneliness on cardiovascular or brain health outcomes. Conclusions Social isolation and loneliness are common and appear to be independent risk factors for worse cardiovascular and brain health; however, consistency of the associations varies by outcome. There is a need to develop, implement, and test interventions to improve cardiovascular and brain health for individuals who are socially isolated or lonely.

Characteristics and factors associated to patients discharging from hospital without an implantable cardioverter defibrillator after out-of-hospital cardiac arrest. EUROPEAN HEART JOURNAL. ACUTE CARDIOVASCULAR CARE 2022; 11:523-531. [PMID: 35714122 DOI: 10.1093/ehjacc/zuac065] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/25/2022] [Revised: 04/25/2022] [Accepted: 05/17/2022] [Indexed: 06/15/2023]
Abstract
AIMS Guidelines recommend that in the absence of reversible cause for sudden cardiac arrest (SCA), implantable cardioverter defibrillator (ICD) should be performed to prevent further fatal event. We sought to describe the frequency and characteristics of patients discharged from the hospital without ICD after the SCA in the daily practice. METHODS AND RESULTS From 2011 to 2018, all SCAs related to a cardiac cause admitted alive across the 48 hospitals of Great Paris Area were prospectively enrolled. Two investigators thoroughly reviewed each medical report to ensure accuracy of the assigned diagnosis towards identifying the cause of SCA and ICD implantation. Out of the 4314 SCA admitted alive at hospital admission, 1064 cardiac-related SCA survivors were discharged alive from hospital, including 356 patients (33.5%) with an ICD and 708 (66.5%) without. The principal underlying cause of SCA among those discharged without an ICD was acute coronary syndrome (ACS; 602, 85%), chronic coronary artery disease (41, 5.8%), structural non-ischaemic heart disease (48, 6.8%), and non-structural heart disease (17, 2.4%). Among ACS-related SCA, 93.8% (602/642) discharged without an ICD. The unique factor associated with non-ICD implantation in the setting of ACS was immediate coronary angioplasty (odds ratio 4.22, 95% confidence interval 1.86-9.30, P < 0.001). CONCLUSION Two-thirds of SCA survivors were discharged without an ICD, mainly in the setting of ACS. The unique factor associated with non-ICD implantation among ACS was immediate coronary angioplasty emphasizing the fact that ACS definition must be precise since associated with ICD implantation or not.

Gender gap in annual preventive care services in France. EClinicalMedicine 2022; 49:101469. [PMID: 35747180 PMCID: PMC9156877 DOI: 10.1016/j.eclinm.2022.101469] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Revised: 04/28/2022] [Accepted: 05/05/2022] [Indexed: 11/03/2022] Open
Abstract
BACKGROUND In France, screening for cardiovascular risk factors is recommended during annual preventive visits. However, data are lacking on the temporal trend in women's uptake to preventive care services, and in cardiovascular and mortality outcomes. The aim of the study was to investigate the participation and mortality of women in annual preventive care services in a major preventive medicine center in France. METHOD Ee conducted repeated cross-sectional studies including a total of 366,270 individuals who had a first examination at the Centre d'Investigations Préventives et Cliniques, France, between January 1992 and December 2011. FINDINGS Women's participation was low below 50 years of age, then increases from 50 to 70 years, and is lower for women older than 70 years. The gap in female participation was more pronounced among individuals with high education, low social deprivation, and no depressive symptoms. Compared with the general population, the screened population had significantly lower standardized mortality ratios (SMRs) among both men and women, for all age ranges. Screened women aged 18-49 years showed a lower mortality gain compared with men of the same age; SMRs did not differ significantly by sex for individuals over 50 years. INTERPRETATION In this community-based sample, compared with men, women's participation to annual preventive care services was lower, and screened women had a lower mortality gain. Despite the demonstrated benefit of annual check-ups on health, there is a gender gap in adherence to preventive programs and in efficiency of screening programs, especially in the young age range. This gap in cardiovascular disease prevention may result in poorer cardiovascular health in women. Urgent adaptations to overcome this gender gap in preventive screening in France are warranted.

Lack of Early Etiologic Investigations in Young Sudden Cardiac Death. Resuscitation 2022; 179:197-205. [PMID: 35788021 DOI: 10.1016/j.resuscitation.2022.06.023] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Revised: 06/09/2022] [Accepted: 06/26/2022] [Indexed: 12/14/2022]
Abstract
BACKGROUND Since majority of sudden cardiac arrest (SCA) victims die in the intensive care unit (ICU), early etiologic investigations may improve understanding of SCA and targeted prevention. METHODS In this prospective, population-based registry all SCA admitted alive across the 48 hospitals of the Paris area were enrolled. We investigated the extent of early etiologic work-up among young SCD cases (<45 years) eventually dying within the ICU. RESULTS From May 2011 to May 2018, 4,314 SCA patients were admitted alive. Among them, 3,044 died in ICU, including 484 (15.9%) young patients. SCA etiology was established in 233 (48.1%) and remained unexplained in 251 (51.9%). Among unexplained (compared to explained) cases, coronary angiography (17.9 vs. 49.4%, P<0.001), computed tomography scan (24.7 vs. 46.8%, P<0.001) and trans-thoracic echocardiography (31.1 vs. 56.7%, P<0.001) were less frequently performed. Only 22 (8.8%) patients with unexplained SCD underwent all three investigations. SCDs with unexplained status decreased significantly over the 7 years of the study period (from 62.9 to 35.2%, P=0.005). While specialized TTE and CT scan performances have increased significantly, performance of early coronary angiography did not change. Autopsy, genetic analysis and family screening were performed in only 48 (9.9%), 5 (1.0%) and 14 cases (2.9%) respectively. CONCLUSIONS More than half of young SCD dying in ICU remained etiologically unexplained; this was associated with a lack of early investigations. Improving early diagnosis may enhance both SCA understanding and prevention, including for relatives. Failure to identify familial conditions may result in other preventable deaths within these families.

Abstract
AIMS Age and sex disparities in out-of-hospital cardiac arrest (OHCA) have been described. Reproductive age may have a protected effect on females vs. males, although results are conflicting. We aimed to clarify this using the Paris Sudden Death Expertise Centre (SDEC) registry. METHODS AND RESULTS The Paris SDEC registry collects OHCAs occurring in the Greater Paris Area. We included all OHCAs of presumed cardiac causes occurring between 2013 and 2018. Patients were divided into age groups: 1-13, 13-50, 50-75, and >75 years. Sex and age disparities in OHCA incidence and outcomes were analysed using multivariable negative binomial and logistic regression models. There were 19 782 OHCAs meeting inclusion criteria: 0.37% aged 1-13 years, 12.4% aged 13-50 years, 40.4% aged 50-75 years, and 46.9% aged >75 years. Adjusted incidence rate ratios (IRRs) in females vs. males were for the youngest to the older age groups: 1.29 [95% confidence interval (CI) 0.78-2.13], 0.54 [0.49-0.59], 0.60 [0.56-0.64], and 0.75 [0.67-0.84]. At reproductive age, females were more likely than males to have a return of spontaneous circulation [adjusted odds ratio (OR) 1.60 (1.27-2.02)], to be alive at hospital admission [OR: 1.49 (1.18-1.89)]. In both sexes, patients aged 13-50 years were more likely to survive at hospital discharge than those aged 50-75 years [males: OR 1.81 (1.49-2.20), females: 2.24 (1.54-3.25)]. However, at reproductive age, no sex disparity was observed in survival at hospital discharge [OR: 1.16 (0.75-1.80)]. CONCLUSION Incidence rate ratios were similar between pre- and post-menopausal aged patients. At reproductive age, no sex disparity in survival at hospital discharge was observed, suggesting that menopausal status may not influence OHCA occurrence and prognosis.

Use of traditional medicine and control of hypertension in 12 African countries. BMJ Glob Health 2022; 7:bmjgh-2021-008138. [PMID: 35654446 PMCID: PMC9163537 DOI: 10.1136/bmjgh-2021-008138] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Accepted: 05/14/2022] [Indexed: 11/26/2022] Open
Abstract
Background Use of traditional medicine (TM) is widespread in sub-Saharan Africa as a treatment option for a wide range of disease. We aimed to describe main characteristics of TM users and estimate the association of TM use with control of hypertension. Methods We used data on 2128 hypertensive patients of a cross-sectional study (convenience sampling), who attended cardiology departments of 12 sub-Saharan African countries (Benin, Cameroon, Congo, Democratic Republic of the Congo, Gabon, Guinea, Côte d’Ivoire, Mauritania, Mozambique, Niger, Senegal, Togo). To model association of TM use with odds of uncontrolled, severe and complicated hypertension, we used multivariable mixed logistic regressions, and to model the association with blood pressure (systolic (SBP) and diastolic (DBP)) we used mixed linear models. All models were adjusted for age, sex, wealth, adherence to hypertension conventional treatment and country (random effect). Results A total of 512 (24%) participants reported using TM, varying across countries from 10% in the Congo to 48% in Guinea. TM users were more likely to be men, living in rural area, poorly adhere to prescribed medication (frequently due to its cost). Use of TM was associated with a 3.87 (95% CI 1.52 to 6.22)/1.75 (0.34 to 3.16) mm Hg higher SBP/DBP compared with no use; and with greater odds of severe hypertension (OR=1.34; 95% CI 1.04 to 1.74) and of any hypertension complication (OR=1.27; 95% CI 1.01 to 1.60), mainly driven by renal complication (OR=1.57; 95% CI 1.07 to 2.29) after adjustment for measured confounders. Conclusions The use of TM was associated with higher blood pressure, more severe hypertension and more complications in Sub-Saharan African countries. The widespread use of TM needs to be acknowledged and worked out to integrate TM safely within the conventional healthcare.

Background
Use of traditional medicine (TM), is widespread in Sub-Saharan Africa as treatment option for a wide range of disease. We aimed to describe the profile of TM users and estimate the association with blood pressure (BP) and control of hypertension among hypertensive patients in a pan-African study.
Methods
We included 2128 participants in the cross-sectional EIGHT study, who attended an outpatient consultation in the cardiology departments of 12 Sub-Saharan African countries (Benin, Cameroon, Congo, Democratic Republic of the Congo, Gabon, Guinea, Côte d’Ivoire, Mauritania, Mozambique, Niger, Senegal, Togo). We describe patients’ characteristics according to TM use. We modelled the odds of uncontrolled hypertension, severe hypertension, and complications of hypertension by multivariable mixed logistic regression, and the linear association with systolic and diastolic BP by linear regression, all adjusted for age, sex, individual wealth index, adherence to hypertension conventional treatment, and country.
Results
A total of 512 (24%) of participants reported using TM, and this percentage varied drastically across countries from 10% in the Congo to 48% in Guinea. TM users were more likely to be male, with poor treatment adherence, reporting missing treatment because it is too expensive, and presenting any complication of hypertension. TM use was associated with greater odds of hypertension (OR=1.30; 95% confidence interval: 0.99, 1.70), severe hypertension (OR=1.34; 1.04, 1.74) and of any complication of hypertension (OR=1.27; 1.01, 1.60), driven by renal complication (OR=1.57; 1.07, 2.29). Use of TM was associated with a 3.87 mmHg higher systolic BP and 1.75 mm Hg higher diastolic BP compared to no use.
Conclusions
In this cross-sectional study of patients with hypertension in 12 Sub-Saharan African countries, we identified that the use of traditional medicine was associated with a poorer control of hypertension and more complications.

Notable paradoxical phenomena in associations between cardiovascular health score, subclinical and clinical cardiovascular disease in the community: The Framingham Heart Study. PLoS One 2022; 17:e0267267.

Abstract
Importance Cardiovascular Health (CVH) scores are inversely associated with prevalent subclinical (SubDz) and incident cardiovascular disease (CVD). However, the majority of people who develop CVD have intermediate or ideal CVH scores, while many with poor CVH profiles escape CVD development. Objective To describe the prevalence of paradoxical relations among CVH, SubDz, and CVD. Design Cohort study, Framingham Study data collected prospectively (1995–2016). Setting Population-based. Participants 7,627 participants (mean age 49 years, 53% women) attending Offspring examinations 6/7 and Third Generation examinations 1/2. Exposures CVH score (range 0–14) constructed from poor, intermediate, or ideal status for each metric (smoking, diet, physical activity, blood pressure, body mass index, fasting glucose, total cholesterol); and prevalent SubDz (≥1 of: increased carotid intimal media thickness, CIMT; left ventricular hypertrophy, LVH; microalbuminuria, MA; elevated ankle brachial index, ABI; coronary artery calcium score ≥100,CAC). Main outcome(s) and measure(s) Ideal CVH (scores 12–14), intermediate CVH (scores 8–11), and poor CVH (0–7). We described three distinct paradoxical phenomena, involving combinations of CVH, SubDz, and CVD, and generated CVD incidence rates and predicted CVD probabilities for all combinations. Results We observed 842 CVD events (median follow-up 13.7 years); 1,663 participants had SubDz. Most individuals with poor CVH (78%) or SubDz (57% for CIMT to 77% for LVH) did not develop CVD on follow-up. Among participants with incident CVD, the majority had intermediate or ideal CVH (68%) or absent SubDz (46% for CAC to 96% for ABI) at baseline. We observed similar paradoxical results in relations between CVH and prevalent SubDz. Poor CVH and prevalent SubDz were each associated with higher CVD incidence rates compared to intermediate or ideal CVH and absent SubDz, respectively. The predicted CVD probability was nearly three-times greater among participants with poor (22%) versus intermediate or ideal CVH (8%). Mean CVD predicted probabilities were nearly three (26% vs. 10% for MA) to six-times (29% vs. 5% for CAC) greater among participants with SubDz versus without SubDz. Findings were consistent within age and sex strata. Conclusions and relevance Although poor CVH and SubDz presence are associated with CVD incidence, paradoxical phenomena involving CVH, SubDz, and CVD are frequently prevalent in the community. Further studies to elucidate biological mechanisms underlying these phenomena are warranted.

Abstract
BACKGROUND We aimed to study sex differences in aortopathy and valve disease among patients undergoing aortic valve replacement and/or surgery for ascending aortic aneurysm, and assess whether differences are specific for patients with bicuspid (BAV) compared to patients with tricuspid aortic valve (TAV). METHODS We used a single-center and observational cohort including 1,045 patients undergoing elective open-heart surgery for aortic valve disease and/or ascending aortic aneurysm at the Karolinska Hospital (Sweden). RESULTS Women (33.0%) were older than men (mean [SD]; 67.9 [11] years vs 62.5 [13] years for men; P < 0.001). No significant sex difference in prevalence of ascending aortic aneurysm was found according to absolute measures (P = 0.19), however, women had a greater dilation of the ascending aorta when normalized for body surface area (mean [SD], 21.8 [6.3] mm/m2 vs 19.3 [4.4] mm/m2 for men; P < 0.001). Among the 560 patients with BAV, women had significantly more AS (adjusted OR, 2.23; 95% CI, 1.19-4.20; P = 0.013) and less AI (adjusted OR 0.42; 95% CI, 0.23-0.78; P < 0.01); whereas no sex difference was found among patients with TAV. CONCLUSIONS In this large study of patients undergoing cardiac surgery, we found greater degree of aortic dilation in women compared to men suggesting a need for earlier monitoring of women. Moreover, women with BAV had a significantly higher prevalence of AS compared to men. These results describe the aorta and valvular characteristics of patients by sex and provide guidance regarding which patients might benefit from closer surveillance.

Abstract
Ethnic inequalities in coronavirus disease 2019 (COVID-19) hospitalizations and mortality have been widely reported, but there is scant understanding of how they are embodied. The UK Biobank prospective cohort study comprises approximately half a million people who were aged 40-69 years at study induction, between 2006 and 2010, when information on ethnic background and potential explanatory factors was captured. Study members were prospectively linked to a national mortality registry. In an analytical sample of 448,664 individuals (248,820 women), 705 deaths were ascribed to COVID-19 between March 5, 2020, and January 24, 2021. In age- and sex-adjusted analyses, relative to White participants, Black study members experienced approximately 5 times the risk of COVID-19 mortality (odds ratio (OR) = 4.81, 95% confidence interval (CI): 3.28, 7.05), while there was a doubling in the South Asian group (OR = 2.05, 95% CI: 1.30, 3.25). Controlling for baseline comorbidities, social factors (including socioeconomic circumstances), and lifestyle indices attenuated this risk differential by 34% in Black study members (OR = 2.84, 95% CI: 1.91, 4.23) and 37% in South Asian individuals (OR = 1.57, 95% CI: 0.97, 2.55). The residual risk of COVID-19 deaths in ethnic minority groups may be ascribed to a range of unmeasured characteristics and requires further exploration.

Abstract
OBJECTIVE In Africa, the number of patients with hypertension is expected to reach 216.8 million by 2030. Large-scale data on antihypertensive medications used in Sub-Saharan Africa (SSA) are scarce.Here, we describe antihypertensive drug strategies and identify treatment factors associated with blood pressure (BP) control in 12 Sub-Saharan countries. SETTING Outpatient consultations for hypertension in urban tertiary cardiology centres of 29 hospitals from 17 cities across 12 SSA countries between January 2014 and November 2015. PARTICIPANTS Patients ≥18 years of age with hypertension were enrolled at any visit during outpatient consultations in the cardiology departments MAIN OUTCOME MEASURE: We collected BP levels, demographic characteristics and antihypertensive treatment use (including traditional medicine) of patients with hypertension attending outpatient visits. BP control was defined as seated office BP <140/90 mm Hg. We used logistic regression with a random effect on countries to assess factors of BP control. RESULTS Overall, 2198 hypertensive patients were included and a total of 96.6% (n=2123) were on antihypertensive medications. Among treated patients, 653 (30.8%) patients received a monotherapy by calcium channel blocker (n=324, 49.6%), renin-angiotensin system blocker (RAS) (n=126, 19.3%) or diuretic (n=122, 18.7%). Two-drug strategies were prescribed in 927 (43.6%) patients including mainly diuretics and RAS (n=327, 42% of two-drug strategies). Prescriptions of three-drugs or more were used in 543 (25.6%) patients. Overall, among treated patients, 1630 (76.7%) had uncontrolled BP, of whom 462 (28.3%) had BP levels ≥180/110 mm Hg, mainly in those on monotherapy. After adjustment for sociodemographic factors, the use of traditional medicine was the only factor significantly associated with uncontrolled BP (OR 1.72 (1.19 to 2.49) p<0.01). CONCLUSION Our study provided large-scale data on antihypertensive prescriptions in the African continent. Among patients declared adherent to drugs, poor BP control was significantly associated with the use of traditional medicine.

[PMID: 33958396 DOI: 10.1136/heartjnl-2020-318787] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2020] [Revised: 04/06/2021] [Accepted: 04/12/2021] [Indexed: 01/23/2023] Open
Abstract
BACKGROUND To date, clinical trials have been underpowered to demonstrate a benefit from ACE inhibitors (ACEis) or angiotensin II receptor blockers (ARBs) in preventing systemic right ventricle (sRV) failure and disease progression in patients with transposition of the great arteries (TGA). This observational study aimed to estimate the effect of ACEi and ARB on heart failure (HF) incidence and mortality in a large population of patients with an sRV. METHODS Data on all patients with an sRV under active follow-up at two tertiary centres between January 2007 and September 2018 were studied. The effect of ACEi and ARB on the incidence of HF and mortality was estimated using a propensity score weighting approach to control confounding. RESULTS Among the 359 patients with an sRV (32.2 (IQR 26.4-38.3) years, 59.3% male, 66% complete TGA with atrial switch repair and 34% congenitally corrected TGA), 79 (22%) had a moderate to severe sRV dysfunction and 138 (38%) were treated with ACEi or ARB. Fourteen (3.6%) patients died, 8 (2.1%) underwent heart transplantation and 46 (11.8%) had a new HF event over a median follow-up of 7.1 (IQR 4.0-9.4) years. On multivariate Cox analysis with adjustment using propensity score weighting approaches, ACEi or ARBs treatment was not significantly associated with a lower HF incidence or mortality in patients with an sRV. CONCLUSIONS Despite significant neurohormonal activation described in patients with an sRV, there is still no evidence of a beneficial effect of ACEi or ARB on morbidity and mortality in this population.

Abstract
Introduction:
Cross-sectional studies have reported the proportion of African-American adults with controlled blood pressure (BP) at a single time point, but few data are available on the proportion that maintains controlled BP over time and the extent to which it is associated with cardiovascular disease (CVD) risk.
Methods:
We analyzed data from 1,414 African-American Jackson Heart Study (JHS) participants taking antihypertensive medication to estimate the proportion with persistent BP control, defined by having controlled BP at the three JHS visits, conducted over a median of 8 years. At each visit, BP control was defined as systolic BP <140 mm Hg and diastolic BP <90 mm Hg. Follow-up for CVD events began after the third visit. We calculated risk ratios (RR) for factors associated with persistent BP control and hazard ratios (HR) for incident CVD events among participants with versus without persistent BP control.
Results:
At baseline, 76.5% (n=1,081) of participants had controlled BP, among which 64.4% (n=696) had persistent BP control. Overall, 49.2% (n=696) of participants had persistent BP control. After adjustment for sex, participants ≥65 compared with <65 years of age were less likely (RR; 95% CI) to have persistent BP control (0.73; 0.64 - 0.83). After age and sex adjustment, participants were more likely to have persistent BP control if they had income ≥$25,000 a year at each study visit (1.25; 1.11 - 1.40), a high school education (1.20; 1.01 - 1.41) and health insurance (1.28; 1.05 - 1.57) at Visit 1, and visited a health professional in the past year at each study visit (1.21; 1.07 - 1.37). The multivariable adjusted HR (95% CI) comparing participants with versus without persistent BP control was 0.71 (0.45 - 1.14) for CVD, 0.85 (0.41 - 1.79) for coronary heart disease, 0.68 (0.28 - 1.64) for stroke, and 0.57 (0.33 - 0.98) for heart failure (HF) (
Table
).
Conclusions:
Less than half of JHS participants taking antihypertensive medication had persistent BP control, putting them at increased risk for CVD, particularly HF.

Temporal trends of cardiovascular health factors among 366 270 French adults. EUROPEAN HEART JOURNAL. QUALITY OF CARE & CLINICAL OUTCOMES 2021; 6:138-146. [PMID: 31328232 PMCID: PMC7132943 DOI: 10.1093/ehjqcco/qcz038] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/21/2019] [Revised: 07/09/2019] [Accepted: 07/14/2019] [Indexed: 11/13/2022]
Abstract
AIMS We aimed to investigate time trends in cardiovascular health (CVH) metrics in the population at large, as well as in important subgroups. METHODS AND RESULTS In this study, we used a community-based sample of 366 270 adults from France who had a standardized examination to assess cardiovascular risk factors between 1992 and 2011 (20 years). Cardiovascular health metrics categorized into ideal, intermediate, and poor categories were computed using smoking, physical activity, body mass index, total cholesterol, blood glucose, and blood pressure. Matching on age, sex, and depression across 5-year periods (1992-96, 1997-2001, 2002-06, and 2007-11) was performed in order to correct for the sociodemographic differences between the examinations at different periods of times. Mean age across all four time periods was 44.7 (SD 13) years and 38% (138 228) were women. Overall, few participants (≤3.5%) met all six ideal CVH metrics at any time point. The prevalence of meeting ≥5 ideal CVH metrics increased from 6.7% in 1992-96 to 15.0% in 2007-11 (P < 0.001). A significant improvement in CVH (meeting ≥5 ideal CVH metrics) from 1992 to 2011 was observed among younger (from 7.5% to 16.6%) and older individuals (from 1.3% to 4.2%), men (from 4.4% to 11.8%) and women (from 10.4% to 20.1%), those with low (from 9.1% to 10.4%) and high education status (from 15% to 18.1%) and those with (from 5.1% to 12.7%) and without depressive symptoms (from 6.8% to 15.1%). However, the rate of improvement was steepest in the most affluent group in comparison with those with lower socio-economic status. CONCLUSION Overall CVH improved from 1992 until 2006 and slightly decreased between 2006 and 2011 in French adults. From 1992 until 2006, the improvement in CVH was less pronounced among those with low socio-economic status as compared to those with a higher socio-economic status.

Abstract
BACKGROUND Significant improvements in survival from out-of-hospital cardiac arrest (OHCA) have been reported; however, these are based only on data from OHCA in whom resuscitation is initiated by emergency medical services (EMS). We aimed to assess the characteristics and temporal trends of OHCA without resuscitation attempt by EMS. METHODS Prospective population-based study between 2011 and 2016 in the Greater Paris area (6.7 million inhabitants). All cases of OHCA were included in collaboration with EMS units, 48 different hospitals, and forensic units. RESULTS Among 15 207 OHCA (mean age 70.7±16.9 years, 61.6% male), 5486 (36.1%) had no resuscitation attempt by EMS. Factors that were independently associated with increase in likelihood of no resuscitation attempt included: age of patients (odds ratio, 1.06 per year [95% CI, 1.05-1.06], P<0.001), female sex (odds ratio, 1.21 [95% CI, 1.10-1.32], P=0.002), OHCA at home location (odds ratio, 3.38 [95%CI, 2.86-4.01], P<0.001), and absence of bystander (odds ratio, 1.94 [95% CI, 1.74-2.16], P<0.001). Overall, the annual number of OHCA increased by 9.1% (from 2923 to 3189, P=0.028). This increase was related to an increase of the annual number of OHCA without resuscitation attempt by EMS by 26.3% (from 993 to 1253, P=0.012), while the annual number of OHCA with resuscitation attempt by EMS did not significantly change (from 1930 to 1936, P=0.416). Considering only cases with resuscitation attempt, survival rate at hospital discharge increased (from 7.3% to 9.5%, P=0.02). However, when considering all OHCA, survival improvement did not reach statistical significance (from 4.8% to 5.7%, P=0.17). CONCLUSIONS We demonstrated an increase of the total number of OHCA related to an increase of the number of OHCA without resuscitation attempt by EMS. This increasing proportion of OHCA without resuscitation attempt attenuates improvement in survival rates achieved in EMS-treated patients.

Explaining ethnic disparities in COVID-19 mortality: population-based, prospective cohort study. MEDRXIV : THE PREPRINT SERVER FOR HEALTH SCIENCES 2021:2021.02.07.21251079.

Abstract
Ethnic disparities in COVID-19 hospitalizations and mortality have been reported but there is scant understanding of how these inequalities are embodied. The UK Biobank prospective cohort study comprises around half a million people who were aged 40-69 years at study induction between 2006 and 2010 when information on ethnic background and potential explanatory factors was captured. Study members were linked to a national mortality registry. In an analytical sample of 448,664 individuals (248,820 women), 354 deaths were ascribed to COVID-19 between 5th March and the end of follow-up on 17th September 2020. In age- and sex-adjusted analyses, relative to White participants, Black study members experienced around seven times the risk of COVID-19 mortality (odds ratio; 95% confidence interval: 7.25; 4.65, 11.33), while there was a doubling in the Asian group (1.98; 1.02, 3.84). Controlling for baseline comorbidities, socioeconomic circumstances, and lifestyle factors explained 53% of the differential in risk for Asian people (1.37; 0.68, 2.77) and 27% in Black study members (4.28; 2.67, 6.86). The residual risk in ethnic minority groups for COVID-19 deaths may be ascribed to unknown genetic factors or unmeasured phenotypes, most obviously racial discrimination.

Abstract
Background The extent to which change in cardiovascular health (CVH) in midlife reduces risk of subsequent cardiovascular disease and mortality is unclear. Methods and Results CVH was computed at 2 ARIC (Atherosclerosis Risk in Communities) study visits in 1987 to 1989 and 1993 to 1995, using 7 metrics (smoking, body mass index, total cholesterol, blood glucose, blood pressure, physical activity, and diet), each classified as poor, intermediate, and ideal. Overall CVH was classified as poor, intermediate, and ideal to correspond to 0 to 2, 3 to 4, and 5 to 7 metrics at ideal levels. There 10 038 participants, aged 44 to 66 years that were eligible. From the first to the second study visit, there was an improvement in overall CVH for 17% of participants and a decrease in CVH for 21% of participants. At both study visits, 28%, 27%, and 6% had poor, intermediate, and ideal overall CVH, respectively. Compared with those with poor CVH at both visits, the risk of cardiovascular disease (hazard ratio [HR], 0.26; 95% CI, 0.20–0.34) and mortality (HR, 0.35; 95% CI, 0.29–0.44) was lowest in those with ideal CVH at both measures. Improvement from poor to intermediate/ideal CVH was also associated with a lower risk of cardiovascular disease (HR, 0.67; 95% CI, 0.59–0.75) and mortality (HR, 0.80; 95% CI, 0.72–0.89). Conclusions Improvement in CVH or stable ideal CVH, compared with those with poor CVH over time, is associated with a lower risk of incident cardiovascular disease and all‐cause mortality. The change in smoking status and cholesterol may have accounted for a large part of the observed association.

Abstract
BACKGROUND Differentials in COVID-19 hospitalisations and mortality according to ethnicity have been reported but their origin is uncertain. We examined the role of socioeconomic, mental health, and pro-inflammatory factors in a community-based sample. METHODS We used data on 340,966 men and women (mean age 56.2 years) from the UK Biobank study, a prospective cohort study with linkage to hospitalisation for COVID-19. Logistic regression models were used to estimate associations between ethnicity and hospitalisation for COVID-19. RESULTS There were 640 COVID-19 cases (571/324,306 White, 31/4,485 Black, 21/5,732 Asian, 17/5,803 Other). Compared to the White study members and after adjusting for age and sex, Black individuals had over a 4-fold increased risk of COVID-19 infection (odds ratio; 95% confidence interval: 4.32; 3.00-6.23), and there was a doubling of risk in the Asian group (2.12; 1.37, 3.28) and the 'other' non-white group (1.84; 1.13, 2.99). After controlling for potential explanatory factors which included neighbourhood deprivation, household crowding, smoking, body size, inflammation, glycated haemoglobin, and mental illness, these effect estimates were attenuated by 33% for Blacks, 52% for Asians and 43% for Other, but remained raised for Blacks (2.66; 1.82, 3.91), Asian (1.43; 0.91, 2.26) and other non-white groups (1.41; 0.87, 2.31). CONCLUSIONS There were clear ethnic differences in risk of COVID-19 hospitalisation and these do not appear to be fully explained by measured factors. If replicated, our results have implications for health policy, including the targeting of prevention advice and vaccination coverage.

Abstract
IMPORTANCE Differentials in COVID-19 incidence, hospitalization and mortality according to ethnicity are being reported but their origin is uncertain. OBJECTIVE We aimed to explain any ethnic differentials in COVID-19 hospitalization based on socioeconomic, lifestyle, mental and physical health factors. DESIGN Prospective cohort study with national registry linkage to hospitalisation for COVID-19. SETTING Community-dwelling. PARTICIPANTS 340,966 men and women (mean age 56.2 (SD=8.1) years; 54.3% women) residing in England from the UK Biobank study. Exposures: Ethnicity classified as White, Black, Asian, and Others. Main Outcome(s) and Measure(s): Cases of COVID-19 serious enough to warrant a hospital admission in England from 16-March-2020 to 26-April-2020. RESULTS There were 640 COVID-19 cases (571/324,306 White, 31/4,485 Black, 21/5,732 Asian, 17/5,803 Other). Compared to the White study members and after adjusting for age and sex, Black individuals had over a 4-fold increased risk of being hospitalised (odds ratio; 95% confidence interval: =4.32; 3.00-6.23), and there was a doubling of risk in the Asian group (2.12; 1.37, 3.28) and the Other non-white group (1.84; 1.13, 2.99). After controlling for 15 confounding factors which included neighbourhood deprivation, education, number in household, smoking, markers of body size, inflammation, and glycated haemoglobin, these effect estimates were attenuated by 33% for Blacks, 52% for Asians and 43% for Other, but remained raised for Blacks (2.66; 1.82, 3.91), Asian (1.43; 0.91, 2.26) and other non-white groups (1.41; 0.87, 2.31). CONCLUSIONS AND RELEVANCE Our findings show clear ethnic differences in risk of hospitalization for COVID-19 which do not appear to be fully explained by known explanatory factors.

Predictive factors of death associated with infective endocarditis in adult patients with congenital heart disease. EUROPEAN HEART JOURNAL. ACUTE CARDIOVASCULAR CARE 2020; 10:2048872620901394.

Abstract
AIMS Infective endocarditis is a severe infection which can occur in adult patients with congenital heart disease. We aimed to determine outcomes and risk factors of death in adult congenital heart disease and to investigate differences with infective endocarditis in non-congenital heart disease. METHODS AND RESULTS Between March 2000 and June 2018, 671 consecutive episodes of infective endocarditis in adult patients were retrospectively recorded. Cases were classified according to the modified Duke classification. All adult congenital heart disease cases were managed by infectious disease specialists and adult congenital heart disease cardiologists. During this period, 142 infective endocarditis episodes (21%) occurred in adult congenital heart disease patients with simple (46.5%), moderate (21.1%), or complex (32.4%) congenital heart disease. In-hospital mortality was 12.7%. The strongest predictive factors of in-hospital death in multivariate analysis were complexity of congenital heart disease (odds ratio (OR) 8.02, 95% confidence interval (CI) 1.53-42.07), age (OR 1.05, 95% CI 1.00-1.19) and white blood cell count 12 g/L or greater (OR 8.72, 95% CI 2.42-31.43). Patients with congenital heart disease were significantly younger (median age 36 vs. 67 years, P<0.001), had undergone more redo cardiac surgeries (35.7% vs. 11.3%, P<0.01) and presented with more right-sided infective endocarditis (39.4% vs. 7.9%, P<0.01) than patients without congenital heart disease. Congenital heart disease was associated with two-fold lower in-hospital mortality rates (OR 0.37, 95% CI 0.19-0.74), independently of age, gender, obesity, renal function and side of infective endocarditis. CONCLUSION Although mortality associated with infective endocarditis is lower in adult patients with congenital heart disease than patients without congenital heart disease, infective endocarditis mortality is particularly high in patients with complex congenital heart disease. Education and prevention about the risk of infective endocarditis is essential, especially in this group.

Abstract
Abstract
Background
Causes, epidemiology and microbiology of infective endocarditis (IE) have evolved in recent decades. Although novel tools for the diagnosis and therapeutic strategies have emerged, mortality and morbidity remain high. These trends may particularly concern the growing population of adults with congenital heart disease (CHD) who are at increased risk for IE.
Purpose
We aimed to characterize IE in CHD patients and describe management and outcome in this setting. We also sought to determine the risk factors associated with in-hospital death in CHD patients.
Methods
From January 2000 to June 2018, 666 consecutive episodes of IE in adults were recorded in our center. Among them, 143 concerned CHD, including 5 implantable cardiac electronic devices-lead infections, all managed by an IE team including CHD specialists. Cases were classified according to modified Duke criteria.
Results
CHD patients were significantly younger (37 years IQR [26–52]), with a more common history of cardiac reoperations (numbers of sternotomies≥2 in 35.7%) and infective endocarditis (19.7%, p<0.01) compared to non-CHD patients. There were more infections of valve-containing prosthetics (44% vs. 30%, p<0.04), and the right heart side (41.5%, p<0.01) in CHD patients. Forty-nine percent of them had a simple CHD, 12.7% a moderate, and 36.4% a complex. A predisposing event could be identified in only 34% of cases. Oral streptococci/Streptococci bovis and Staphylococcus aureus were the most frequently microorganisms isolated (32.4% and 20.4%, respectively). Surgery was performed in 90 episodes (62%), and was selected in emergency (<24h) in 61% (figure 1). In-hospital mortality was 12.7% and was directly related to IE in 10/18 cases. CHD patients had a significant lower risk of death compared to non-CHD patients (OR=0.47, p=0.026, p<0.01), even after adjustment for age, and the infected heart side. On multivariate analysis the complexity of CHD (if simple CHD: OR=0.07 IQR [0.01 to 0.44], p<0.01) and the white blood cell count (OR=1.18 IQR [1.04 to 1.33], p=0.01) were the strongest predictive factors of in-hospital death in the CHD group.
Conclusions
Mortality associated with IE in CHD patients is lower than in acquired heart disease. The multidisciplinary approach by IE team and CHD specialists may have improved management and outcome in this setting. However, risk for death remains high in complex lesions. Larger prospective studies on IE in adults with CHD are needed to develop guidelines in these complex patients.

Abstract
Background
High Blood Pressure is the worldwide leading global burden of disease risk factor. In Sub-Saharan Africa, the number of adults with raised blood pressure has alarmingly increased from 0.59 to 1.13 billion between 1975 and 2015. Blood pressure-lowering medicines are cornerstone of cardiovascular risk reduction. Data on management of anti-hypertensive drugs in sub-Saharan Africa are squarce.
Purpose
Our study aims to describe antihypertensive drugs strategies in Africa.
Methods
We conducted a cross-sectional survey in urban clinics during outpatient consultation specialized in hypertension cardiology departments of 29 medical centers from 17 cities across 12 African countries (Benin, Cameroon, Congo, Democratic Republic of Congo, Gabon, Guinea, Ivory Coast, Mauritania, Mozambic, Niger, Senegal, Togo). Data were collected on demographics, treatment and standardized BP measures were made among the hypertensive patients attending the clinics. Country income was retrieved from the World Bank database. All analyses were performed through scripts developed in the R software (3.4.1 (2017–06–30)).
Results
A total of 2198 hypertensive patients (58.4±11.8 years; 39.9% male) were included. Among whom 2123 (96.6%) had at least one antihypertensive drug. Overall, 30.8% (n=653) received monotherapy and calcium-channel blockers (49.6%) were the most common monotherapy prescribed follow by diuretics (18.7%). Two-drug strategies were prescribed for 927 patients (43.6%). Diuretics and Angiotensin-converting enzyme inhibitors was the combination most frequently prescribed (33.7%). Combination of three drugs or more was used in 25.6% (n=543) of patients. The proportion of drugs strategies differed significantly according to countries (p<0.001), monotherapy ranged from 12.7% in Niger to 47.1% in Democratic Republic of the Congo (figure). Furthermore we observed a significantly difference of strategies between low and middle income countries (55.3% and 44.7% of monotherapy respectively) (p<0.001). According to hypertension grades 1, 2 and 3, the proportion of three-drugs or more combination was 25%, 28% and 34% in middle-income and lower in low-income countries (18%, 19% and 25%). Furthermore, Grade 3 hypertension in low income countries was still treated with monotherapy (36%) instead of 19% in middle income countries (p<0.01).
Antihypertensive strategies by country
Conclusion
Our study described antihypertensive drugs use across 12 sub-Saharan countries, and identified disparities specific to the income context. Inequity in access to drugs combination is a serious barrier to tackle the burden of hypertension in Africa.

Abstract
Abstract
Background
Individuals with SH have high 10-year risk of cardiovascular disease, especially when additional risk factors or target organ damage are present. Though some data from in-hospital or selected populations are available, there are no studies reporting community-level prevalence of Severe Hypertension (SH) in sub-Saharan Africa.
Purpose
Using a cross-sectional design in Abidjan (Ivory Coast), we assessed prevalence of Severe Hypertension among adults.
Methods
Study participants were recruited within the framework of The Heart Fund's global health initiative. Data were collected in August 2016 from 6 randomly selected sites, ensuring representativeness of both urban and rural areas. Blood pressure (BP) was measured twice, 10 minutes apart, after optimal resting time. Blood pressure measurement were standardized between sites and SH was defined as systolic blood pressure ≥180 and/or diastolic blood pressure ≥110 mmHg at both readings. Demographics and data on cardiovascular history/risk factors were collected in the field. Ethics approval for the study was obtained from the National Ethical Committee of Côte d'Ivoire and written informed consent was obtained from all adult patients.
Results
Among 1,785 subjects examined, 1,182 aged between 18 and 75 years were included in this analysis. The prevalence of SH was 14.1% (12.5% females vs 17.0% males; P=0.03) (Figure). Among participants with severe hypertension, 28.9% were either undiagnosed or untreated. Alarmingly, subjects at high cardiovascular risk (age ≥60 years and/or obese) had even higher prevalence of overall SH (29.6% and 24.9%, respectively) as well as undiagnosed/untreated SH (29.4% and 24.6%). SH prevalence was almost double in urban compared to rural areas (17.0% vs. 9.2%, P=0.02); however, conversely, undiagnosed/untreated SH was significantly higher in rural areas (50.4% vs 21.9%). Compared to normal bodyweight, those who were overweight and obese had a 1.95-fold (95% CI, 1.30–2.93; P<0.001)and 4.24-fold (95% CI, 2.68–6.74; P<0.001)increased odds of SH (adjusting for age and sex), respectively. Similarly, participants ≥60 years had a 6.04-fold (95% CI, 3.93–9.36; P<0.001)increased risk of undiagnosed SH compared to under 50 years. Finally, men had higher odds of SH compared to women (OR 1.71, 95% CI, 1.19–2.47; P=0.004).

Conclusion(s)
Our community-based study revealed very high prevalence of SH among adults in Abidjan area, with almost one out of every seven having SH. This underscores SH as a growing public health problemin sub-Saharan Africa.More concerning, a significant (almost one third) proportion of them were either undiagnosed or untreated.

Epidemiological transition in morbidity: 10-year data from emergency consultations in Dakar, Senegal. BMJ Glob Health 2019; 4:e001396. [PMID: 31406585 PMCID: PMC6666800 DOI: 10.1136/bmjgh-2019-001396] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2019] [Revised: 04/29/2019] [Accepted: 05/25/2019] [Indexed: 01/30/2023] Open
Abstract
Background It is thought that low-income countries are undergoing an epidemiological transition from infectious to non-communicable diseases; however, this phenomenon is yet to be examined with long-term data on morbidity. Methods We performed a prospective evaluation of all emergency medical consultations at a major emergency service provider in Dakar, Senegal from 2005 to 2014. Using standardised definitions, the primary diagnosis for each consultation was classified using the International Classification of Diseases-10 and then broadly categorised as ‘infectious’, ‘non-communicable’ and ‘other’ diseases. Morbidity rates for each year in the 10-year observation period were plotted to depict the epidemiological transition over time. To quantify the yearly rate ratios of non-communicable over infectious diagnosis, we used a generalised Poisson mixed model. Results Complete data were obtained from 49 702 visits by African patients. The mean age was 36.5±23.2 and 34.8±24.3 years for women and men, respectively. Overall, infections accounted for 46.3% and 42.9% and non-communicable conditions 32.2% and 40.1% of consultations in women and men, respectively. Consultation for non-communicable compared with infectious conditions increased by 7% every year (95% CI: 5% to 9%; p<0.0001) over the 10 years. Consultations for non-communicable condition were more likely in women compared with men (RR=1.29, 95% CI: 1.18, 1.40) and at older ages (RR=1.27; 95% CI 1.25, 1.29 for 10-year increase in age). Conclusion Using high-quality disease morbidity data over a decade, we provide novel data showing the epidemiological transition of diseases as manifested in emergency service consultations in a large Sub-Saharan African city. These results can help reorientation of healthcare policy in Sub-Saharan Africa.

Abstract
IMPORTANCE Evidence is limited regarding the relation between cardiovascular health level and dementia risk. OBJECTIVE To investigate the association between cardiovascular health level, defined using the 7-item tool from the American Heart Association (AHA), and risk of dementia and cognitive decline in older persons. DESIGN, SETTING, AND PARTICIPANTS Population-based cohort study of persons aged 65 years or older from Bordeaux, Dijon, and Montpellier, France, without history of cardiovascular diseases or dementia at baseline who underwent repeated in-person neuropsychological testing (January 1999-July 2016) and systematic detection of incident dementia (date of final follow-up, July 26, 2016). EXPOSURES The number of the AHA's Life's Simple 7 metrics at recommended optimal level (nonsmoking, body mass index <25, regular physical activity, eating fish twice a week or more and fruits and vegetables at least 3 times a day, cholesterol <200 mg/dL [untreated], fasting glucose <100 mg/dL [untreated], and blood pressure <120/80 mm Hg [untreated]; score range, 0-7) and a global cardiovascular health score (range, 0-14; poor, intermediate, and optimal levels of each metric assigned a value of 0, 1, and 2, respectively). MAIN OUTCOMES AND MEASURES Incident dementia validated by an expert committee and change in a composite score of global cognition (in standard units, with values indicating distance from population means, 0 equal to the mean, and +1 and -1 equal to 1 SD above and below the mean). RESULTS Among 6626 participants (mean age, 73.7 years; 4200 women [63.4%]), 2412 (36.5%), 3781 (57.1%), and 433 (6.5%) had 0 to 2, 3 to 4, and 5 to 7 health metrics at optimal levels, respectively, at baseline. Over a mean follow-up duration of 8.5 (range, 0.6-16.6) years, 745 participants had incident adjudicated dementia. Compared with the incidence rate of dementia of 1.76 (95% CI, 1.38-2.15) per 100 person-years among those with 0 or 1 health metrics at optimal levels, the absolute differences in incident dementia rates for 2, 3, 4, 5, and 6 to 7 metrics were, respectively, -0.26 (95% CI, -0.48 to -0.04), -0.59 (95% CI, -0.80 to -0.38), -0.43 (95% CI, -0.65 to -0.21), -0.93 (95% CI, -1.18 to -0.68), and -0.96 (95% CI, -1.37 to -0.56) per 100 person-years. In multivariable models, the hazard ratios for dementia were 0.90 (95% CI, 0.84-0.97) per additional optimal metric and 0.92 (95% CI, 0.89-0.96) per additional point on the global score. Furthermore, the gain in global cognition associated with each additional optimal metric at baseline was 0.031 (95% CI, 0.009-0.053) standard units at inclusion, 0.068 (95% CI, 0.045-0.092) units at year 6, and 0.072 (95% CI, 0.042-0.102) units at year 12. CONCLUSIONS AND RELEVANCE In this cohort of older adults, increased numbers of optimal cardiovascular health metrics and a higher cardiovascular health score were associated with a lower risk of dementia and lower rates of cognitive decline. These findings may support the promotion of cardiovascular health to prevent risk factors associated with cognitive decline and dementia.
