Long-term PM 2.5 exposure associated with severity of angina pectoris and related health status in patients admitted with acute coronary syndrome: Modification effect of genetic susceptibility and disease history. ENVIRONMENTAL RESEARCH 2024; 257:119232. [PMID: 38810823 DOI: 10.1016/j.envres.2024.119232] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Revised: 05/08/2024] [Accepted: 05/25/2024] [Indexed: 05/31/2024]
Abstract
Long-term particulate matter with aerodynamic diameters ≤2.5 μm (PM2.5) exposure has been associated with the occurrence of acute coronary syndrome (ACS). However, the impact of PM2.5 exposure and its components on the severity of angina pectoris and disease-related health status in patients hospitalized for ACS is understudied. To assess the association between long-term exposure to PM2.5 components and the angina pectoris severity in ACS patients, as well as the modification effects of genetic factors and disease history in north China. During 2017-2019, 6729 ACS patients were collected in Shandong Province and Beijing, with their angina pectoris severity evaluated using Seattle Angina Questionnaire (SAQ). The 0-3 years' average concentrations of PM2.5 and its five major components were assigned to each patient's residential address. Linear mixed-effects model, weighted quantile regression, and quantile g-computation were used to estimate the effects of both single and joint associations between PM2.5 components and SAQ scores. The interactive effect was estimated by polygenic risk scores and disease history. For each interquartile range increase in PM2.5, the overall SAQ score changed by -3.71% (95%CI: -4.54% to -2.88%), with score of angina stability more affected than angina frequency and other dimensions of angina pectoris severity. Sulfate and ammonium were major contributors to the effect of PM2.5 exposure. Significant modification effect was only observed for disease history, especially for the dimension of physical limitation. Among a series of pre-existing diseases, patients with a family history of coronary artery disease, previous percutaneous coronary intervention or coronary artery bypass grafting, and stroke were more susceptible to PM2.5 exposure than others. Greater exposure to PM2.5 is associated with more serious angina pectoris and worse disease-related health status in ACS patients. Public health and clinical priority should be given to cutting down key effective components and protecting highly vulnerable individuals.

Abstract
Objective Fear of recurrence is a common psychosocial sequela among patients with heart disease. Analyses of coronary heart disease, particularly in elderly patients, are relatively rare. This study aimed to investigate the current situation in this context, as well as the influencing fear factors concerning recurrence in elderly patients with coronary heart disease. Methods A total of 200 elderly outpatients with coronary heart disease were recruited to participate in this survey from a tertiary hospital in Baoding (China). The questionnaires included items from the Disease Progression Simplified Scale, the Simplified Coping Style Questionnaire, and the Social Support Rating Scale (SSRS). Univariate and multivariate regression analyses were adopted to investigate the influencing factors on the fear of recurrence. Results The fear of recurrence score in elderly patients with coronary heart disease was (38.46 ± 8.13), among which 119 cases (59.5%) scored higher than 34 points. The SSRS total average score was (34.89 ± 9.83) points. Positive coping style and social support were negatively correlated with the total score of recurrence fear (r = − 0.621, − 0.413, both P < 0.001). There was a positive correlation between negative coping style and the total score of recurrence fear (r = 0.232, P < 0.001). Multiple linear regression analysis showed that the course of the disease, the number of disease recurrence cases, active coping, and social support were relevant factors in fear of recurrence (all P < 0.05). Conclusion The detection rate of fear of recurrence in elderly patients with coronary heart disease was relatively high but could be reduced by active interventions and enhancing social support.

Association of myocardial infarction and angina pectoris with obesity and biochemical indices in the South Korean population. Sci Rep 2022; 12:13769. [PMID: 35962047 PMCID: PMC9374724 DOI: 10.1038/s41598-022-17961-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Accepted: 08/03/2022] [Indexed: 11/08/2022] Open
Abstract
The best obesity index for myocardial infarction or angina pectoris (MIAP) risk assessment remains controversial. Furthermore, the association between biochemical indices and these diseases is unclear. This study examined associations of obesity and biochemical indices with MIAP in the Korean population. This large-scale cross-sectional study was based on the Korea National Health and Nutrition Survey dataset from 2010 to 2019. A total of 22,509 subjects (9452 men and 13,057 women) aged ≥ 50 years were included. Participants consisted of 21,426 individuals without MIAP (men = 8869, women = 12,557) and 1083 with MIAP (men = 583, women = 500). Binary logistic regression was performed to examine the association of MIAP with obesity and biochemical indices. The prevalence of MIAP in Korean adults aged ≥ 50 years was 4.81% (6.57% among men, 3.98% among women). MIAP was more strongly associated with total cholesterol than other variables in men (adjusted OR = 0.436 [0.384-0.495], adjusted p < 0.001) and women (adjusted OR = 0.541 [0.475-0.618], adjusted p < 0.001). The waist-to-height ratio (adjusted OR = 1.325 [1.082-1.623], adjusted p = 0.007) and waist circumference (adjusted OR = 1.290 [1.072-1.553], adjusted p = 0.007) showed a significant association with MIAP in men, with no association between obesity indices and MIAP in women after adjustment. The association between biochemical indices and MIAP differed slightly according to sex. Only total cholesterol, creatinine, and platelets were associated with MIAP in both men and women.

Abstract
Abstract
Objective:
Regarding the secondary prevention of cardiovascular disease (CVD), there is great interest in preventing recurrent cardiovascular events (RCVEs). The prognostic importance of liver fibrosis scores (LFSs) has previously been reported in various CVDs. We hypothesized that LFSs might also be useful predictors for RCVEs in patients with prior cardiovascular events (CVEs). Herein, we aimed to evaluate the associations of LFSs with RCVEs in a large, real-world cohort of coronary artery disease (CAD) patients with a prior CVE.
Methods:
In this multicenter prospective study, 6527 consecutive patients with angiography-diagnosed CAD who had experienced a prior CVE (acute coronary syndrome, stroke, percutaneous coronary intervention, or coronary artery bypass grafting) were enrolled. LFSs were computed according to the published formulas: non-alcoholic fatty liver disease fibrosis score (NFS) includes age, body mass index (BMI), impaired fasting glycemia or diabetes mellitus (DM), aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ratio, platelets, and albumin; fibrosis-4 (FIB-4) includes age, AST, ALT, and platelets; Forns score includes age, gamma-glutamyltransferase (GGT), and platelets; BARD includes BMI, AST/ALT ratio, and DM; GGT/platelet ratio includes GGT and platelets; AST/ALT ratio includes AST and ALT; and AST/platelet ratio index includes AST and platelets. The originally reported cutoffs were used for the categorization of low-, intermediate-, and high-score subgroups. All patients were followed up for the occurrence of RCVEs (comprising cardiovascular death, non-fatal myocardial infarction, and stroke). Cox and Poisson regression analyses were used to assess the relationship of baseline LFSs with the risk of RCVE.
Results:
During a mean follow-up of (54.67 ± 18.80) months, 532 (8.2%) RCVEs were recorded. Intermediate and high NFS, FIB-4, Forns, and BARD scores were independently associated with an increased risk of RCVE (hazard ratios ranging from 1.42 to 1.75 for intermediate scores and 1.35 to 2.52 for high scores). In the subgroup analyses of sex, age, BMI, DM, and hypertension status, the increased risk of RCVEs with high LFSs (NFS, FIB-4, Forns, and BARD) was maintained across the different subgroups (all P < 0.05).
Conclusion:
This study showed that LFSs are indeed independently associated with RCVEs, suggesting that LFSs may be used as novel tools for risk stratification in CAD patients with a prior CVE.

Abstract
Background Prior work suggests that obesity may confer a survival advantage among persons with cardiovascular disease (CVD). This obesity “paradox” is frequently studied in the context of prevalent disease, a stage in the disease process when confounding from illness-related weight loss and selective survival are especially problematic. Our objective was to examine the association of obesity with mortality among persons with incident CVD, where biases are potentially reduced, and to compare these findings with those based on prevalent disease. Methods We used data from the Health and Retirement Study, an ongoing, nationally representative longitudinal survey of U.S. adults age 50 years and older initiated in 1992 and linked to Medicare claims. Cox proportional hazard models were used to estimate the association between weight status and mortality among persons with specific CVD diagnoses. CVD diagnoses were established by self-reported survey data as well as Medicare claims. Prevalent disease models used concurrent weight status, and incident disease models used pre-diagnosis weight status. Results We examined myocardial infarction, congestive heart failure, stroke, and ischemic heart disease. A strong and significant obesity paradox was consistently observed in prevalent disease models (hazard of death 18–36% lower for obese class I relative to normal weight), replicating prior findings. However, in incident disease models of the same conditions in the same dataset, there was no evidence of this survival benefit. Findings from models using survey- vs. claims-based diagnoses were largely consistent. Conclusion We observed an obesity paradox in prevalent CVD, replicating prior findings in a population-based sample with longer-term follow-up. In incident CVD, however, we did not find evidence of a survival advantage for obesity. Our findings do not offer support for reevaluating clinical and public health guidelines in pursuit of a potential obesity paradox.

Abstract
PURPOSE We review the use of oral antiplatelet (OAP) therapies in acute coronary syndrome (ACS) management for nurse practitioners (NPs), focusing on current guideline recommendations. DATA SOURCES Treatment guidelines and clinical articles from PubMed. CONCLUSIONS Guidelines recommend that dual antiplatelet therapy with a P2Y12 inhibitor and aspirin be initiated for ACS management. The P2Y12 inhibitor clopidogrel has established efficacy, but is associated with suboptimal and delayed platelet inhibition and variability in response. The newer P2Y12 inhibitors prasugrel and ticagrelor have demonstrated superior efficacy outcomes versus clopidogrel. Consequently, non-ST-segment elevation ACS (NSTE-ACS) guidelines now recommend that ticagrelor be used in preference to clopidogrel for patients treated with stents or managed medically. Because of their higher potency, prasugrel and ticagrelor are associated with increased bleeding rates versus clopidogrel, but with no increased risk of severe or life-threatening bleeding. Guidelines recommend dual antiplatelet therapy be continued ≥12 months in both medically managed and stented ACS patients, and in some cases beyond this, in absence of high bleeding risk. Updated guidelines assign preference to ticagrelor over clopidogrel for maintenance therapy in patients with NSTE-ACS and ST-elevation myocardial infarction. IMPLICATIONS FOR PRACTICE Enhanced NP understanding of OAP agents and current guidelines could contribute to improved ACS patient management.

Abstract
Peripheral arterial disease (PAD) is underdiagnosed and undertreated. This is despite the high vascular morbidity and mortality rates associated with PAD. There is also evidence that quitting smoking, improving the lipid profile, lowering the blood pressure, and administering antiplatelet drugs reduce the risk of vascular events in these patients. Secondary prevention for patients with PAD is yet to meet the standard of care for those with ischemic heart disease. The authors surveyed 200 claudicants attending a vascular clinic with additional follow-up in a risk modification clinic. After a median follow-up of 28 months (range: 6-65) there was a significant (p=0.001) improvement in walking distance; 34 patients (17%) had a vascular ischemic event. Of those, 11 patients (5.5%) had worsening intermittent claudication and 9 had a stroke/transient ischemic attack; 9 events (4.5%) were fatal. The lipid targets were met in 76% the patients. Half the smokers quit smoking and 94% of the patients were taking antiplatelet drugs or anticoagulants. Blood pressure reached the accepted target in 87% of the patients. Secondary prevention in patients with PAD may reduce the risk of vascular events. Aggressive risk modification is therefore recommended.

Abstract
The authors investigated the effects of rosuvastatin, beyond its lipid-lowering activity, on several nonlipid metabolic variables, along with its safety and tolerability, in patients treated for primary hyperlipidemia. Patients (n=55) with primary hyperlipidemia were open-label assigned to the recommended starting dose of rosuvastatin 10 mg/day, and serum metabolic variables were measured at baseline and after 8 and 20 weeks. Treatment with rosuvastatin produced significant reductions in total cholesterol, low-density lipoprotein cholesterol (LDL-C), apolipoprotein B, nonhigh-density lipoprotein cholesterol (non HDL-C), and triglyceride concentrations, whereas HDL-C, apolipoprotein A-I, and lipoprotein(a) levels did not change significantly from baseline. The LDL-C treatment target was achieved in 71% of patients. No significant variations in renal function parameters (serum creatinine and creatinine clearance), insulin resistance estimates, and serum concentrations of uric acid, total homocysteine, vitamin B12, and folic acid were observed during the period of treatment. High-sensitivity C-reactive protein levels were significantly lowered by rosuvastatin therapy (median values, 3.1 vs 2.0 vs 1.9 mg/L, at 0, 8, and 20 weeks, respectively; p<0.0001). In conclusion, rosuvastatin at 10 mg/day is a highly effective, safe, and well-tolerated monotherapy option for patients with primary hyperlipidemia, with a favorable antiinflammatory potential and nondeteriorating effects on renal function.

Abstract
BACKGROUND Primary hyperparathyroidism (PHPT) is associated with hypertension, coronary atherosclerosis and other cardiovascular diseases. We aimed to evaluate serum parathyroid hormone (PTH) levels as an independent risk factor for coronary heart disease (CHD) in subjects with serum calcium within the reference range. DESIGN Population-based cross-sectional study. METHODS The Tromsø Study was attended by 27159 subjects aged 25-79 years. Serum PTH was measured in 3570 subjects. They all completed a questionnaire on medical history, including questions on angina pectoris and myocardial infarction along with a food-frequency questionnaire. A total of 1459 men and 1753 women with serum calcium 2.20-2.60 mmol/l, serum creatinine<121 micromol/l and who did not use diuretics were included in the present study. Linear regression was used to reveal associations between PTH, age, body mass index, serum calcium, calcium intake, cholesterol, blood pressure, glycosylated haemoglobin (HbA1c) and smoking status. A logistic regression model was used to find the independent predictors of CHD. RESULTS When stratified for age the rate of CHD was higher in the subjects with serum PTH > 6.8 pmol/l than in those with normal or low serum PTH levels [relative risk 1.67, 95% confidence interval (CI) 1.26-2.23 in men and 1.78, 95% CI 1.22-2.57 in women]. The highest PTH quartile (> 3.50 pmol/l in men and > 3.30 pmol/l in women) predicted CHD, with odds ratios of 1.70 (95% CI 1.08-2.70) for men and 1.73 (95% CI 1.04-2.88) for women, versus the lowest PTH quartile (< 1.90 pmol/l for men and <1.80 pmol/l for women). CONCLUSIONS Serum PTH predicts CHD in subjects with calcium levels within the reference range. This may indicate a role for PTH in the development of CHD.

Abstract
Background Prognosis after a first myocardial infarction (MI) is influenced by primary risk factors as well as secondary risk factors. There is still a lack of follow-up studies of well-characterized patient cohorts assessing the relative importance of these factors. Design A cohort of 1635 patients (aged 45-70 years) surviving at least 28 days after a first MI were followed for 6-9 years with regard to recurrent MI/fatal coronary heart disease (CHD). Data were collected through questionnaires, physical examinations, and medical records. Methods Hazard ratios (HR) with 95% confidence intervals (CI) for different risk factors were calculated using the Cox proportional hazard model. Results Of the primary risk factors, diabetes in both sexes was the most important predictor of recurrent MI/fatal CHD, multivariate-adjusted HR in men 1.6 (95% CI; 1.0-2.4) and in women 2.5 (95% CI; 0.9-6.9). Other primary risk factors with prognostic influence were job strain, HR 1.5 (95% CI; 1.0-2.1), and central obesity, HR 1.4 (95% CI; 1.0-2.0), in men and a low level of apolipoprotein A1, HR 2.3 (95% CI; 1.1-5.0), and high-density lipoprotein cholesterol, HR 1.9 (95% CI; 0.9-4.1), in women. The secondary risk factors most detrimental for prognosis were heart failure in men, HR 2.2 (95% CI; 1.2-4.0), and a high peak acute cardiac enzyme level in women, HR 4.4 (95% CI; 2.0-9.7). Conclusions Long-term follow-up of patients who survived at least 28 days after a first MI shows that several primary cardiovascular risk factors, particularly diabetes, contribute to the increased risk of recurrent MI/fatal CHD.

Abstract
OBJECTIVE Atherosclerosis is a chronic disease characterized by lipid accumulation in the arterial wall. After myocardial infarction (MI), atherosclerotic plaques are infiltrated by inflammatory myeloid cells that aggravate the disease and increase the risk of secondary myocardial ischemia. Splenic myelopoiesis provides a steady flow of myeloid cells to inflamed atherosclerotic lesions after MI. Therefore, targeting myeloid cell production in the spleen could ameliorate increased atherosclerotic plaque inflammation after MI. APPROACH AND RESULTS Here we show that MI increases splenic myelopoiesis by driving hematopoietic stem and progenitor cells into the cell cycle. In an atherosclerotic mouse model, E-selectin inhibition decreased hematopoietic stem and progenitor cell proliferation in the spleen after MI. This led to reduced extramedullary myelopoiesis and decreased myeloid cell accumulation in atherosclerotic lesions. Finally, we observed stable atherosclerotic plaque features, including smaller plaque size, reduced necrotic core area, and thicker fibrous cap after E-selectin inhibition. CONCLUSIONS Inhibiting E-selectin attenuated inflammation in atherosclerotic plaques, likely by reducing leukocyte recruitment into plaques and by mitigating hematopoietic stem and progenitor cell activation in the spleen of mice with MI.

Abstract
The objective of this study was to investigate the effects of lipid-lowering treatment on renal function in patients with peripheral arterial disease (PAD). This was a retrospective study of hyperlipidemic claudicants referred to a vascular surgery and risk modification clinic. Serum creatinine and urate concentrations and the fasting lipid profile were measured pretreatment and after 3-4 months of treatment with 20 mg/day simvastatin. In 103 consecutive patients with PAD (57 men; 46 women), median age 67 years (range: 51 to 83) there was a significant decrease in serum creatinine from a mean (SD) of 87 (12) μmol/L pretreatment to 84 (12) μmol/L post-treatment (p<0.0001). This difference was more marked in the tertile of patients with the highest baseline creatinine levels. There was also a significant reduction in serum urate from 0.37 (0.07) mmol/L to 0.35 (0.07) mmol/L (p<0.0001). Both these effects were independent of the degree of total cholesterol (TC) or low-density lipoprotein (LDL) cholesterol reduction. There was a significant reduction in TC from 6.6 (1.0) to 5.2 (0.8) mmol/L and LDL cholesterol from 4.3 (1.0) to 2.8 (0.7) mmol/L; both p<0.0001. Significant improvement also occurred in the high-density lipoprotein cholesterol and triglyceride levels. Cholesterol lowering with simvas tatin 20 mg/day improved indices of renal function after 3-4 months of treatment in hyper lipidemic patients with PAD. Further studies are needed to establish and define the clinical relevance of these findings, especially in patients with different degrees of renal failure.

Abstract
Background Risk factors are important in cardiovascular (CV) medicine for risk stratification of patients. We aimed to compare the traditional risk factors to clinical variables for the prediction of secondary cardiovascular events. Methods and Results For this study, 3229 patients with known coronary artery disease (CAD) were included. We calculated whether the traditional risk factors, diabetes mellitus, increased LDL/HDL ratio, arterial hypertension and smoking alone and in combination with the clinical variables, ejection fraction, creatinine clearance, multi-vessel disease and CRP concentration predict the outcome cardiovascular death or non-fatal myocardial infarction (N = 432) during the mean follow-up time of 4.2 ± 2.0 years. In this cohort diabetes mellitus was the risk factor with the strongest influence regarding occurrence of secondary events (hazard ratio; HR:1.70, confidence interval; CI 95%: 1.36-2.11; P<0.0001), followed by LDL/HDL ratio and smoking. However, risk stratification is further improved by using additional clinical variables like ejection fraction (HR:3.30 CI 95%:2.51-4.33; P>0.0001) or calculated creatinine clearence (Cockroft-Gault formula) (HR:2.26 CI 95%:1.78-2.89; P<0.0001). Further ameliorating risk stratification from the clinical variables were CRP and multi-vessel disease. The most precise risk prediction was achieved when all clinical variables were added to the CV risk factors. Conclusion Diabetes mellitus has the strongest influence to predict secondary cardiovascular events in patients with known CAD. Risk stratification can further be improved by adding CV risk factors and clinical variables together. Control of risk factors is of paramount importance in patients with known CAD, while clinical variables can further enhance prediction of events.

Clinical indicators for recurrent cardiovascular events in acute coronary syndrome patients treated with statins under routine practice in Thailand: an observational study. BMC Cardiovasc Disord 2015; 15:55. [PMID: 26076586 PMCID: PMC4467053 DOI: 10.1186/s12872-015-0052-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2015] [Accepted: 06/01/2015] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND Acute coronary syndrome (ACS) patients are at very high cardiovascular risk and tend to have recurrent cardiovascular events. The clinical indicators for subsequent cardiovascular events are limited and need further investigation. This study aimed to explore clinical indicators that were associated with recurrent cardiovascular events following index hospitalization. METHODS The data of patients hospitalized with ACS at a tertiary care hospital in northern Thailand between January 2009 and December 2012 were retrospectively reviewed from medical charts and the electronic hospital database. The patients were classified into three groups based on the frequency of recurrent cardiovascular events (nonfatal ACS, nonfatal stroke, or all-cause death) they suffered: no recurrent events (0), single recurrent event (1), and multiple recurrent events (≥2). Ordinal logistic regression was performed to explore the clinical indicators for recurrent cardiovascular events. RESULTS A total of 405 patients were included; 60 % were male; the average age was 64.9 ± 11.5 years; 40 % underwent coronary revascularization during admission. Overall, 359 (88.6 %) had no recurrent events, 36 (8.9 %) had a single recurrent event, and 10 (2.5 %) had multiple recurrent events. The significant clinical indicators associated with recurrent cardiovascular events were achieving an LDL-C goal of < 70 mg/dL (Adjusted OR = 0.43; 95 % CI = 0.27-0.69, p-value < 0.001), undergoing revascularization during admission (Adjusted OR = 0.44; 95 % CI = 0.24-0.81, p-value = 0.009), being male (Adjusted OR = 1.85; 95 % CI = 1.29-2.66, p-value = 0.001), and decrease estimated glomerular filtration rate (Adjusted OR = 2.46; 95 % CI = 2.21-2.75, p-value < 0.001). CONCLUSION The routine clinical practice indicators assessed in ACS patients that were associated with recurrent cardiovascular events were that achieving the LDL-C goal and revascularization are protective factors, while being male and having decreased estimated glomerular filtration rate are risk factors for recurrent cardiovascular events. These clinical indicators should be used for routinely monitoring patients to prevent recurrent cardiovascular events in ACS patients.

Abstract
BACKGROUND Obesity is a cardiovascular risk factor, but the obesity paradox in patients undergoing percutaneous coronary intervention is poorly understood. METHODS AND RESULTS Assessment of Dual Antiplatelet Therapy With Drug-Eluting Stents (ADAPT-DES) was a prospective, multicenter study of patients undergoing drug-eluting stent implantation. Overall, 780 patients (916 culprit lesions) were evaluated by grayscale and virtual histology-intravascular ultrasound pre-percutaneous coronary intervention. Poststenting intravascular ultrasound was done in 780 patients (894 treated lesions). Patients were divided into body mass index (BMI) tertiles. The high-BMI group had more diabetes mellitus, hypertension, and hyperlipidemia and more frequent plaque ruptures compared with the low-BMI group. At the minimal lumen area site, the high-BMI group had a larger plaque area (11.7 [11.0-12.4] versus 9.8 [9.3-10.4] mm(2)) and a greater plaque burden (77.3% [76.1%-78.5%] versus 74.4% [73.1%-75.8%]) compared with the low-BMI group; however, a larger external elastic membrane area (14.6 [13.8-15.3] versus 12.7 [12.1-13.3] mm(2)) resulted in a similar minimal lumen area compared with the low-BMI group. Post stenting, the high-BMI group had a significantly larger stent area versus the lower-BMI group. At 1-year follow-up, the high-BMI group was associated with less clinically driven target lesion revascularization compared with the low-BMI group in both the overall and the propensity-matched cohorts. CONCLUSIONS A high BMI was associated with a greater plaque burden; however, a larger external elastic membrane preserved lumen dimensions and was associated with a larger stent area during intravascular ultrasound-guided stent implantation. Thus, despite more comorbidities, greater plaque burden, and more plaque rupture, a high BMI was not associated with worse outcomes after drug-eluting stent implantation.

Relationship of body mass index with total mortality, cardiovascular mortality, and myocardial infarction after coronary revascularization: evidence from a meta-analysis. Mayo Clin Proc 2014; 89:1080-100. [PMID: 25039038 DOI: 10.1016/j.mayocp.2014.04.020] [Citation(s) in RCA: 70] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2013] [Revised: 03/18/2014] [Accepted: 04/17/2014] [Indexed: 12/22/2022]
Abstract
OBJECTIVE To investigate the relationship of body mass index (BMI) with total mortality, cardiovascular (CV) mortality, and myocardial infarction (MI) after coronary revascularization procedures (coronary artery bypass grafting [CABG] and percutaneous coronary intervention [PCI]). PATIENTS AND METHODS Systematic search of studies was conducted using PubMed, CINAHL, Cochran CENTRAL, Scopus, and the Web of Science databases. We identified studies reporting the rate of MI, CV mortality, and total mortality among coronary artery disease patients' postcoronary revascularization procedures in various BMI categories: less than 20 (underweight), 20-24.9 (normal reference), 25-29.9 (overweight), 30-34.9 (obese), and 35 or more (severely obese). Event rates were compared using a random effects model assuming interstudy heterogeneity. RESULTS A total of 36 studies (12 CABG; 26 PCI) were selected for final analyses. The risk of total mortality (relative risk [RR], 2.59; 95% CI, 2.09-3.21), CV mortality (RR, 2.67; 95% CI, 1.63-4.39), and MI (RR, 1.79; 95% CI, 1.28-2.50) was highest among patients with low BMI at the end of a mean follow-up period of 1.7 years. The risk of CV mortality was lowest among overweight patients (RR, 0.81; 95% CI, 0.68-0.95). Increasing degree of adiposity as assessed by BMI had a neutral effect on the risk of MI for overweight (RR, 0.92; 95% CI, 0.84-1.01), obese (RR, 0.99; 95% CI, 0.85-1.15), and severely obese (RR, 0.93; 95% CI, 0.78-1.11) patients. CONCLUSION After coronary artery disease revascularization procedures (PCI and CABG), the risk of total mortality, CV mortality, and MI was highest among underweight patients as defined by low BMI and CV mortality was lowest among overweight patients.

Abstract
BACKGROUND Data on the incidence, trends over time and predictors of ischemic stroke after an acute myocardial infarction (AMI) are sparse for patients with chronic kidney disease (CKD). METHODS Data for unselected AMI patients were obtained from the Swedish Register of Information and Knowledge about Swedish Heart Intensive Care Admissions (RIKS-HIA) between 2003 and 2010. Patients with and without CKD were compared. Multiple logistic regression was performed to identify predictors of ischemic stroke during the hospitalization for AMI, Kaplan-Meier analysis was used to analyze the 1-year postdischarge ischemic stroke trends over time and Cox regression analysis was used to identify predictors. RESULTS Of 118,434 AMI patients, 40,679 had CKD. The CKD patients had more extensive previous cardiovascular disease and received less reperfusion and secondary preventive therapies than the patients without CKD. An inhospital ischemic stroke occurred in 2.3 and 1.2% of CKD and non-CKD patients, respectively. The incidence of ischemic stroke during hospitalization for AMI was stable during the study period. The occurrence of ischemic stroke after hospital discharge decreased between 2003-2004 and 2009-2010 from 4.1 to 2.5% in CKD patients and from 2.0 to 1.3% in non-CKD patients, respectively. Percutaneous coronary intervention (PCI) and statins were independently associated with a reduced risk of stroke after discharge from hospital. CONCLUSIONS Ischemic stroke is a more common complication after an AMI in CKD patients than in non-CKD patients, but the risk has decreased in recent years. The increased use of PCI and statins may have contributed to this reduction.

Abstract
BACKGROUND Incidence, any trend over time, and predictors of ischemic stroke after an acute myocardial infarction (AMI) in diabetic patients are unknown. METHODS AND RESULTS Data for 173,233 unselected patients with an AMI, including 33,503 patients with diabetes mellitus, were taken from the Swedish Register of Information and Knowledge about Swedish Heart Intensive Care Admissions (RIKS-HIA) during 1998 to 2008. Ischemic stroke events were recorded during 1 year of follow-up. Patients with diabetes mellitus more often had a history of cardiovascular disease, received less reperfusion therapy, and were treated with acetylsalicylic acid, P2Y12 inhibitors, and statins to a lesser extent compared with patients without diabetes mellitus. However, the use of evidence-based therapies increased markedly in both groups during the study period. The incidence of ischemic stroke during the first year after AMI decreased from 7.1% to 4.7% in patients with diabetes mellitus and from 4.2% to 3.7% in patients without diabetes mellitus. Risk reduction was significantly larger in the diabetic subgroup. Reperfusion therapy, acetylsalicylic acid, P2Y12 inhibitors, and statins were independently associated with the reduced stroke risk. CONCLUSIONS Ischemic stroke is a fairly common complication after an AMI in patients with diabetes mellitus, but the risk of stroke has decreased during recent years. The increased use of evidence-based therapies contributes importantly to this risk reduction, but there is still room for improvement.

Abstract
OBJECTIVE To compare the risk of subsequent myocardial infarction (MI) between patients with and without type 2 diabetes mellitus (T2DM) in a retrospective cohort study. RESEARCH DESIGN AND METHODS Patients with their first MI recorded in the U.K. General Practice Research Database in 1997-2008 were classified as T2DM, diagnosed before or within 28 days after the date of the first recorded MI (i.e., the index date), or non-T2DM. Patients diagnosed within 28 days after the index date were assumed to have developed T2DM at baseline (i.e., before the index date). The primary outcome was the first subsequent MI. The secondary outcomes were all-cause death and a composite of all-cause death or subsequent MI. Cox proportional hazards models were fit to obtain hazard ratios (HRs) for all outcomes. RESULTS A total of 7,411 T2DM (median age 72 years; men 63.4%) and 48,726 non-T2DM patients (median age 69 years; men 65.3%) were included. The crude incidences (per 1,000 patient-years) in T2DM vs. non-T2DM were 32.8 vs. 22.8 for subsequent MI, 83.7 vs. 52.1 for all-cause death, and 106.5 vs. 69.9 for the composite end point. The adjusted HRs for subsequent MI, all-cause death, and their combination were 1.41 (95% CI 1.27-1.56), 1.50 (1.41-1.60), and 1.42 (1.34-1.50), respectively, in women and 1.23 (1.14-1.34), 1.40 (1.33-1.47), and 1.33 (1.27-1.39) in men. CONCLUSIONS Compared with non-T2DM, T2DM was associated with an increased risk for subsequent MI, all-cause death, and their composite end point. The risk tends to be higher in women than in men.

Abstract
BACKGROUND AND PURPOSE Acute myocardial infarction (AMI) increases the risk of ischemic stroke, and mortality among these patients is high. Here, we aimed to estimate the 1-year mortality reliably after AMI complicated by ischemic stroke. We also aimed to identify trends over time for mortality during 1998-2008, as well as factors that predicted increased or decreased mortality. METHODS Data for 173 233 unselected patients with AMI were collected from the Swedish Register of Information and Knowledge about Swedish Heart Intensive Care Admissions registry for 1998-2008. Specifically, we analyzed 1-year follow-up and mortality data for patients with AMI with and without ischemic stroke. Kaplan-Meyer analysis was used to analyze mortality trends over time, and Cox regression analysis was used to identify uni- and multivariate predictors of mortality. RESULTS The 1-year mortality was 36.5% for AMI complicated by ischemic stroke and 18.3% for AMI without stroke. Mortality decreased over time in patients with and without ischemic stroke. The absolute decreases in mortality were 9.4% and 7.5%, respectively. Reperfusion and secondary preventive therapies were associated with a decreased mortality rate. CONCLUSIONS Mortality after AMI complicated by an ischemic stroke is very high but decreased from 1998 to 2008. The increased use of evidence-based therapies explains the improved prognosis.

Abstract
Obesity is considered a major risk factor for cardiovascular disease, hypertension, and diabetes by National and International Committees. For this reason, they advocate weight loss and prevention of obesity. However, several studies in patients with established coronary artery disease (CAD), congestive heart failure, and hypertension have shown an inverse relationship between obesity and mortality, the so called "obesity paradox," whereas other studies have not shown such a relationship. In studies showing the obesity paradox (OP), body mass index (BMI) was used, almost exclusively as an index of obesity, although is a poor discriminator of total body fatness. Recent studies using better indices of obesity such as waist circumference (WC) and waist to hip ratio (WHR) have shown that high WC and WHR were directly and positively associated with higher event rate and total mortality in these patients. Because the OP could convey the wrong message in obese patients, the validity and true nature of the OP will be examined in this concise review. A Medline search of the English literature was performed between 2000 and September 2012, and 46 pertinent articles were selected for this review. The majority of these studies do not support an OP and those that do have used almost exclusively BMI as an index of obesity. Therefore, based on recent studies using other indices of body fat distribution, such as WC and WHR, besides BMI, the true existence of OP has been questioned and needs to be confirmed by future studies.

Abstract
The reactivity of the stress system may change during the life course. In many—but not all—humans the stress reactivity decreases, once the individual is chronically exposed to a stressful and unsafe environment (e.g., poverty, work with high demands, unhappy martial relationship). Such an adaptation is referred to as habituation. Stress habituation allows alleviating the burden of chronic stress, particularly cardiovascular morbidity and mortality. Interestingly, two recent experiments demonstrated low stress reactivity during a mental or psychosocial challenge in subjects with a high body mass. In this focused review we attempt to integrate these experimental findings in a larger context. Are these data compatible with data sets showing a prolonged life expectancy in corpulent people? From the perspective of neuroenergetics, we here raise the question whether “obesity” is unhealthy at all. Is the corpulent phenotype possibly the result of “adaptive phenotypic plasticity” allowing optimized survival in stressful environments?

Abstract
BACKGROUND According to the National Health survey only 3% of the population has controlled hypertension. This study was designed to elucidate the knowledge about hypertension in hypertensive patients at three tertiary care centers in Karachi. Secondly we sought to compare the knowledge of those with uncontrolled hypertension and controlled hypertension. METHODS It was a cross-sectional study conducted at The Aga Khan University hospital (AKUH), Ziauddin Hospital (ZH) and Civil hospital, Karachi (CHK. All diagnosed Hypertensive patients (both inpatients and outpatients) coming to a tertiary care hospital in Pakistan aged > 18 years were included. Patients were categorized into 2 groups: controlled and uncontrolled hypertension based on their initial BP readings on presentation Uncontrolled Hypertension was defined as average BP ≥ 140/90 mm Hg in patients on treatment. Controlled Hypertension (HTN) was defined as average BP <140/90 mm Hg in patients on treatment. Standardized methods were used to record BP in the sitting position. Knowledge was recorded as a15 item question. Primary outcome was knowledge about hypertension. RESULTS A total of 650 participants were approached and consented 447 were found eligible. 284(63.5%) were from Aga Khan University, 101(22.6) from Dow University of health sciences and 62(13.9) were from Ziauddin University. Mean (SD) age of participants was 57.7(12) years, 50.1(224) were men. Controlled hypertension was present in 323(72.3) and uncontrolled hypertension was present in 124(27.4). The total mean (SD) Knowledge score was 20.97(4.93) out of a maximum score of 38. On comparison of questions related to knowledge between uncontrolled and controlled hypertension, there was statistically significant different in; meaning of hypertension (p <0.001), target SBP(p0.001), target DBP(p 0.001), importance of SBP versus DBP, improvement of health with lowering of blood pressure (p 0.002), high blood pressure being asymptomatic (p <0.001), changing lifestyle improves blood pressure(p 0.003),hypertension being a lifelong disease (<0.001), lifelong treatment with antihypertensives(<0.001) and high blood pressure being part of aging(<0.001). On comparison of knowledge as a composite score between uncontrolled and controlled hypertensive; Mean (SD) score was 21.85(4.74) v18.67 (4.70) (p value: < 0.001). On multivariate analysis; gender β (95% CI) 1.67(0.75, 2.59) p <0.001, uncontrolled blood pressure; -2.70(-3.76,-1.67) p <0.001, Sindhi ethnicity; -1.79(-3.25,-3.27) p 0.01 and pukhtoon ethnicity; -2.72(-4.13,-1.32) p <0.001 were significantly associated with knowledge score. CONCLUSION Knowledge about hypertension in hypertensive patients is not adequate and is alarmingly poor in patients with uncontrolled hypertension. More emphasis needs to be made on target blood pressure and need for taking antihypertensives for life to patients by physicians.

Abstract
Background Stroke is a potential complication of acute coronary syndrome (ACS). The aim of this study was to identify the prevalence, risk factors predisposing to stroke, in-hospital and 1-year mortality among patients presenting with ACS in the Middle East. Methods For a period of 9 months in 2008 to 2009, 7,930 consecutive ACS patients were enrolled from 65 hospitals in 6 Middle East countries. Results The prevalence of in-hospital stroke following ACS was 0.70%. Most cases were ST segment elevation MI-related (STEMI) and ischemic stroke in nature. Patients with in-hospital stroke were 5 years older than patients without stroke and were more likely to have hypertension (66% vs. 47.6%, P = 0.001). There were no differences between the two groups in regards to gender, other cardiovascular risk factors, or prior cardiovascular disease. Patients with stroke were more likely to present with atypical symptoms, advanced Killip class and less likely to be treated with evidence-based therapies. Independent predictors of stroke were hypertension, advanced killip class, ACS type –STEMI and cardiogenic shock. Stroke was associated with increased risk of in-hospital (39.3% vs. 4.3%) and one-year mortality (52% vs. 12.3%). Conclusion There is low incidence of in-hospital stroke in Middle-Eastern patients presenting with ACS but with very high in-hospital and one-year mortality rates. Stroke patients were less likely to be appropriately treated with evidence-based therapy. Future work should be focused on reducing the risk and improving the outcome of this devastating complication.

Abstract
Although there appears to be a role for statins in reducing cerebrovascular events, the exact role of different lipid fractions in the etiopathogenesis of cerebrovascular disease (CVD) is not well understood. A secondary analysis of data collected for the placebo arm (n = 2,078) of the Cholesterol and Recurrent Events (CARE) trial was performed. The CARE trial was a placebo-controlled trial aimed at testing the effect of pravastatin on patients after myocardial infarction. Patients with histories of CVD were excluded from the study. A Cox proportional-hazards model was used to evaluate the association between plausible risk factors (including lipid fractions) and risk for first incident CVD in patients after myocardial infarction. At the end of 5 years, 123 patients (6%) had incident CVD after myocardial infarction (76 with stroke and 47 with transient ischemic attack). Baseline non-high-density lipoprotein (HDL) cholesterol level emerged as the only significant lipid risk factor that predicted CVD; low-density lipoprotein cholesterol and HDL cholesterol were not significant. The adjusted hazard ratios (adjusted for age, gender, hypertension, diabetes mellitus, and smoking) for CVD were 1.28 (95% confidence interval [CI] 1.06 to 1.53) for non-HDL cholesterol, 1.14 (95% CI 0.96 to 1.37) for low-density lipoprotein cholesterol, and 0.90 (95% CI 0.75 to 1.09) for HDL cholesterol (per unit SD change of lipid fractions). This relation held true regardless of the level of triglycerides. After adjustment for age and gender, the hazard ratio for the highest natural quartile of non-HDL was 1.76 (95% CI 1.05 to 2.54), compared to 1.36 (95% CI 0.89 to 1.90) for low-density lipoprotein cholesterol. In conclusion, non-HDL cholesterol is the strongest predictor among the lipid risk factors of incident CVD in patients with established coronary heart disease.

Abstract
History of hypertension is a frequent finding in patients with acute myocardial infarction (AMI) and its recurring association with female sex, diabetes, older age, less frequent smoking and more frequent vascular comorbidities composes a risk profile quite distinctive from the normotensive ischemic counterpart.Antecedent hypertension associates with higher rates of death and morbid events both during the early and long-term course of AMI, particularly if complicated by left ventricular dysfunction and/or congestive heart failure. Renin-angiotensin-aldosterone system blockade, through either angiotensin-converting enzyme inhibition, angiotensin II receptor blockade or aldosterone antagonism, exerts particular benefits in that high-risk hypertensive subgroup.In contrast to the negative implications carried by antecedent hypertension, higher systolic pressure at the onset of chest pain associates with lower mortality within 1 year from coronary occlusion, whereas increased blood pressure recorded after hemodynamic stabilization from the acute ischemic event bears inconsistent relationships with recurring coronary events in the long-term follow-up.Whether antihypertensive treatment in post-AMI hypertensive patients prevents ischemic relapses is uncertain. As a matter of fact, excessive diastolic pressure drops may jeopardize coronary perfusion and predispose to new acute coronary events, although the precise cause-effect mechanisms underlying this phenomenon need further evaluation.

Impact of body weight and extreme obesity on the presentation, treatment, and in-hospital outcomes of 50,149 patients with ST-Segment elevation myocardial infarction results from the NCDR (National Cardiovascular Data Registry). J Am Coll Cardiol 2012; 58:2642-50.

Abstract
OBJECTIVES The aim of this study was to assess the impact of extreme (class III) obesity (body mass index [BMI] ≥40 kg/m(2)) on care and outcomes in patients with ST-segment elevation myocardial infarction (STEMI). BACKGROUND Although its prevalence is increasing rapidly, little is known about the impact of extreme obesity on STEMI presentation, treatments, complication rates, and outcomes. METHODS The relationship between BMI and baseline characteristics, treatment patterns, and risk-adjusted in-hospital outcomes was quantified for 50,149 patients with STEMI from the National Cardiovascular Data Registry (NCDR) ACTION Registry-GWTG. RESULTS The proportions of patients with STEMI by BMI category were as follows: underweight (BMI <18.5 kg/m(2)) 1.6%, normal weight (18.5 kg/m(2) ≤BMI <25 kg/m(2)) 23.5%, overweight (25 kg/m(2) ≤BMI <30 kg/m(2)) 38.7%, class I obese (30 kg/m(2) ≤BMI <35 kg/m(2)) 22.4%, class II obese (35 kg/m(2) ≤BMI <40 kg/m(2)) 8.7%, and class III obese 5.1%. Extreme obesity was associated with younger age at STEMI presentation (median age 55 years for class III obese vs. 66 years for normal weight); a higher prevalence of diabetes, hypertension, and dyslipidemia; a lower prevalence of smoking; and less extensive coronary artery disease and higher left ventricular ejection fraction. Process-of-care measures were similar across BMI categories, including the extremely obese. Using class I obesity as the referent, risk-adjusted in-hospital mortality rates were significantly higher only for class III obese patients (adjusted odds ratio: 1.64; 95% confidence interval: 1.32 to 2.03). CONCLUSIONS Patients with extreme obesity present with STEMI at younger ages and have less extensive coronary artery disease, better left ventricular systolic function, and similar processes and quality of care. Despite these advantages, extreme obesity remains independently associated with higher in-hospital mortality.

Abstract
BACKGROUND Blood pressure management is a key issue among patients with coronary heart disease (CHD). The present study aimed to identify particular patient groups that may need to be specifically targeted in secondary prevention of CHD. METHODS EUROASPIRE III is a cross-sectional study conducted in 2006-2007 among patients up to 80 years of age hospitalized for CHD. Patients from 76 centres in 22 European regions were examined on average 15 months after hospitalization. Logistic regression analysis was applied to investigate factors associated with blood pressure control and knowledge of target blood pressure using the cut-point of less than 140/90 mmHg. RESULTS Among 7649 patients using antihypertensive medication 50.4% achieved blood pressure control and 49.4% provided accurate knowledge of target blood pressure. Obese patients were less likely to show controlled blood pressure [odds ratio (OR) 0.72, 95% confidence interval (CI) 0.65-0.80] and accurate knowledge of blood pressure target values (OR 0.80, 95% CI 0.72-0.90). Dyslipidaemia was negatively associated with blood pressure control and accurate target knowledge. Patients with diabetes mellitus less frequently achieved blood pressure control (OR 0.89, 95% CI 0.79-0.99). Accurate knowledge of target blood pressure was positively related to blood pressure control (OR 1.12, 95% CI 1.00-1.24). Patients who received advice by a health professional to reduce salt intake, to reduce weight, and to increase physical activity more frequently showed accurate knowledge of blood pressure target values. CONCLUSION Blood pressure control and knowledge of target blood pressure are inappropriate in the European high-risk population of coronary patients. Particularly CHD patients with obesity, diabetes, and dyslipidaemia need better management and control of elevated blood pressure.

Abstract
Obesity promotes a cascade of secondary pathologies including diabetes, insulin resistance, dyslipidemia, inflammation, thrombosis, hypertension, the metabolic syndrome, and OSA, which collectively heighten the risk for cardiovascular disease. Obesity may also be an independent moderator of cardiac risk apart from these comorbid conditions. Rates of obesity and cardiac disease continue to rise in a parallel and exponential manner. Because obesity is potentially one of the most modifiable mediators of cardiovascular morbidity and mortality, effective treatment and prevention interventions should have a profound and favorable impact on public health.

Abstract
OBJECTIVE Prospective studies have shown that effort-reward imbalance (ERI) at work is associated with the incidence of a first coronary heart disease (CHD) event. However, it is unknown whether ERI at work increases the risk of recurrent CHD events. The objective of this study was to determine whether ERI at work and its components (effort and reward) increase the risk of recurrent CHD in post-myocardial infarction (post-MI) workers. METHODS We carried out a prospective cohort study of 669 men and 69 women who returned to work after a first MI. ERI at work was assessed by telephone interview using validated scales of reward and psychological demands. The outcome was a composite of fatal CHD, nonfatal MI, and unstable angina. CHD risk factors were documented in medical files and by interview. The participants were followed up for a mean period of 4.0 years (1998-2005). RESULTS During the follow-up, 96 CHD events were documented. High ERI and low reward were associated with recurrent CHD (respective adjusted hazard ratios [HRs] = 1.75, 95% confidence interval [CI] = 0.99-3.08, and HR = 1.77, 95% CI = 1.16-2.71). There was a gender interaction showing stronger effects among women (respective adjusted HRs for high ERI and low reward: HR = 3.95, 95% CI = 0.93-16.79, and HR = 9.53, 95% CI = 1.15-78.68). CONCLUSIONS Post-MI workers holding jobs that involved ERI or low reward had increased risk of recurrent CHD.

Abstract
BACKGROUND Atherothrombosis is a systemic disease that may manifest as acute ischemic events in multiple vascular beds. Patients who have experienced an atherothrombosis-related ischemic event in 1 vascular bed are at risk for developing ischemic events in other vascular beds. Antiplatelet therapy demands an understanding of the balance between arterial thrombosis benefit and adverse event risk. Clinical trials indicate that dual antiplatelet therapy with aspirin and the newer thienopyridines increases the risk of bleeding in patients with acute coronary syndromes (ACS) with prior cerebrovascular events. Informed clinical decision making requires a better understanding of the real-world prevalence of cerebrovascular events. OBJECTIVE AND PURPOSE To estimate the prevalence of stroke and/or transient ischemic attack (TIA) among patients with ACS within US health plan populations. METHODS A retrospective, observational cohort study was conducted of patients with ACS in 5 health care claims databases. The index event was defined as the first documented inpatient health care claim for myocardial infarction or unstable angina. Patients with ≥12 months of pre-index medical care encounter information were included. Stroke/TIA was identified by the first health care claim for these conditions any time prior to or within 90 days following the index ACS event. RESULTS Across all databases, between 3.8% and 15.7% of patients with ACS had prior stroke/TIA and between 3.4% and 11.7% of patients with ACS with no history of cerebrovascular events had documented stroke/TIA following the index ACS hospitalization. CONCLUSION Despite important differences between the various database populations, there is a high prevalence of documented stroke/TIA in patients with ACS both prior to and following the ACS event. These real-world findings, set within the context of the increased bleeding risk observed with the newer thienopyridines, are important considerations when selecting antiplatelet therapy for patients with ACS.

Abstract
In this review, we have analyzed the role of visceral obesity in the occurrence of metabolic syndrome (MetS). MetS is a common metabolic disorder that has been related recently to the increasing prevalence of obesity. The disorder is defined in various ways, but in the near future a new definition(s) should be applicable worldwide. The pathophysiology has been largely attributed, in the past years, to insulin resistance, although several epidemiological and pathophysiological data now indicate visceral obesity as a main factor in the occurrence of all the components of MetS. In view of this, relationships among visceral obesity, free fatty acids, dyslipidemia and insulin resistance have been reported. In addition, the effects of some adipocytokines and other proinflammatory factors produced by fat accumulation on the occurrence of MetS have been also emphasized. Accordingly, the "hypoadiponectinemia hypothesis" has been proposed as the most interesting to explain the pathophysiology of MetS. The epidemiologic, pathophysiologic and clinical data reported seem to indicate that MetS might be considered a fatal consequence of visceral obesity.

Abstract
AIM To assess the changes in the utilization of antihypertensive, and lipid-lowering drugs among all adult Finnish coronary heart disease (CHD) patients between 2000 and 2006, and to evaluate the treatment and control of hypertension and dyslipidemia in a population-based sample of CHD patients. METHODS From the databases of the Social Insurance Institution of Finland, 192,440 CHD patients aged 30 years or more in 2000 and 206,394 in 2006, respectively, were identified. Changes in the utilization of antihypertensive and lipid-lowering drugs were determined. In addition, from the Health 2000 Survey representing the whole Finnish population aged 30 years or more, 527 CHD patients were identified, to assess their characteristics and control of hypertension and dyslipidemia. RESULTS Between the fall of 2000 and spring of 2001, 75% of the CHD patients were classified as hypertensives and 85% of these used antihypertensive medication. From 2000 to 2006, the utilization of lipid-lowering, and antihypertensive drugs increased from 33 to 52% and from 74 to 78%, respectively. Moreover, combination antihypertensive medication increased from 37 to 48%. Amidst the patients using antihypertensive drugs, the use of renin-angiotensin system blockers increased from 27 to 46% because of more than a three-fold increase in the use of angiotensin receptor blockers. CONCLUSION Utilization of antihypertensive agents (especially angiotensin receptor blockers) and lipid-lowering drugs has increased remarkably by the end of 2006. However, the treatments are still far from optimal.

Abstract
We evaluated the effect of body weight on the outcome of Middle Eastern patients presenting with acute coronary syndrome (ACS). Analysis of the Gulf Registry of Acute Coronary Events (Gulf RACE) survey that included 7843 consecutive patients hospitalized with ACS was made. Patients were categorized as normal weight, overweight, or obese based on their body mass index (BMI). Overall, 67% of patients were overweight or obese; obese and overweight patients were more likely to be female and have diabetes mellitus, hypertension, dyslipidemia, and less likely to be smokers. In-hospital mortality, congestive heart failure, cardiogenic shock, and strokes were comparable between the groups, although patients with obesity were more likely to have recurrent ischemia and major bleeding complication in the ST-elevation myocardial infarction group. Excess body weight with ACS is associated with higher risk profile characteristics without an increase in hospital mortality or cardiovascular events.

Abstract
OBJECTIVE Obesity is an independent cardiovascular risk factor, but its prognostic role in patients with peripheral arterial disease (PAD) is not well defined. Accordingly, we assessed the impact of body mass index (BMI) and waist circumference (WC) on cardiovascular risk in a homogeneous cohort of PAD patients. METHODS BMI and WC were measured in 190 consecutive PAD patients with ABI <0.90, referred to our university hospital for intermittent claudication. The occurrence of cardiac, cerebrovascular and peripheral events was prospectively assessed. The ability to classify risk was determined by calculating the hazard ratios (HRs) and c-statistics. RESULTS During a median follow-up of 31.5 months, 63 patients (33.2%) had a cardiovascular event. Considered as continuous variables, both adiposity indices were significantly associated with increased cardiovascular risk, even after adjustment for possible confounding factors (HR=1.08, 95% CI 1.01-1.15, P=0.045 for BMI and HR=1.04, 95% CI 1.01-1.07, P=0.004 for WC). When BMI and WC were included together in a fully adjusted Cox model, the significant association between BMI and cardiovascular risk disappeared (HR=0.98, 95% CI 0.88-1.10, P=0.772), whereas WC remained significantly associated with a worse outcome (HR=1.04, 95% CI 1.01-1.08, P=0.033). The better discriminative ability of WC vs BMI was confirmed by the c-statistic, which was significantly higher for WC (0.63, 95% CI 0.56-0.70) than for BMI (0.56, 95% CI 0.51-0.63, P=0.038). CONCLUSIONS Abdominal obesity and, to a lesser degree, general obesity worsen the prognosis of PAD patients independently of possible confounding factors. Weight reduction should be integrated in the active management of these patients.

Abstract
BACKGROUND Acute Myocardial Infarction (AMI) is one of the main causes of mortality and disability in Colombia. The factors associated to a new event in surviving subjects to a first AMI in our population have not yet been fully identified. METHODS Two hundred and ninety five surviving subjects to a first AMI (58.8±12.6 years) were included in a prospective cohort study between 2000 and 2006. Lipid profile, glycemia and plasma insulin levels were measured. Deaths of cardiovascular origin, a new AMI, unstable angina, heart failure, stroke, new myocardial revascularization or angioplasty were considered new cardiovascular events. RESULTS The study included 61 (20.6%) women and 234 (79.4%) men. The mean follow up time was 50±30 months with a 38.9% incidence of new events. Fifty five patients (18.6%) were diabetic. Bi-varied analysis identified as risk factors for a new cardiovascular event the presence of: hypertension, anterior descending coronary artery stenosis, intrahospital cardiac failure, age over 55, low income, lack of education, Killip III-IV, heart rate over 76 bpm, pulse pressure over 80 mmHg, total cholesterol over 200 mg/dl and insulin over 10 IU/ml. After logistic regression analysis, the log values of insulin remained as the only significant predictor for new cardiovascular events. CONCLUSIONS Hyperinsulinism was the most important factor associated to the occurrence of new cardiovascular events in Colombian patients with AMI, which emphasizes the pivotal role of insulin resistance in the physiopathologic mechanisms of atherosclerosis, especially in undeveloped countries.

Abstract
Smoking and other forms of tobacco use are major risk factors for cardiovascular disease. The effect of cigarette smoking on cardiovascular health is evident even at the lowest levels of exposure. Yet, the adverse effects of smoking are reversible, with cardiovascular risk decreasing substantially within the first 2 years of smoking cessation. Significantly, the mortality from coronary heart disease is reduced more through smoking cessation than by other secondary preventive therapies such as cholesterol lowering. Smoking cessation is a highly effective way to improve cardiovascular health in smokers and extremely cost-effective. However, smoking cessation therapies are not implemented maximally if they are implemented at all, perhaps because smoking is seen as a lifestyle choice or because smokers frequently relapse, as indicated by very low long-term quit rates. Too often, healthcare professionals, including lipidologists and cardiologists, do little to address their patients' smoking status, in spite of its impact on cardiovascular health. With the advent of new therapies to treat the nicotine addiction that results from smoking and other tobacco use, it is hoped that physicians will be more proactive in encouraging and implementing smoking cessation programs for their patients, with the goal of increasing long-term quit rates, and reducing the morbidity and mortality associated with cardiovascular disease.

Abstract
Studies of recurrent coronary events in obese postinfarction patients show mixed results despite potential importance of obesity-related pathophysiologic processes and associated markers in establishing and predicting risk. The study aim was to determine specific markers of recurrent risk in obese postinfarction patients. Nondiabetic patients of the Thrombogenic Factors and Recurrent Coronary Events (THROMBO) postinfarction study were classified according to BMI as normal weight (<25 kg/m(2)), overweight (25.0-29.9 kg/m(2)), and obese (> or = 30 kg/m(2)). Cox multivariable regression with adjustment for significant clinical covariates was performed in each group monitoring outcome (cardiac death, myocardial infarction (MI), or unstable angina with 26 months follow-up) as a function of 17 thrombogenic, inflammatory, and metabolic blood markers and 17 cardiovascular disease-associated genetic polymorphisms. Results revealed no statistically significant genetic or blood marker variables in normal or overweight patients. For obese postinfarction patients, elevated lipoprotein(a) (Lp(a))was found to be a highly significant risk marker with hazard ratio and 95% confidence interval of 3.94 (2.11-7.35), P = 0.000017 (upper tertile vs. lower two tertiles). Additionally, elevated Lp(a) was found to interact with the -75G>A polymorphism of the apolipoprotein A-I gene and the -250G>A polymorphism of the hepatic lipase gene in establishing risk. We conclude that interactions of elevated Lp(a) with polymorphisms of the apolipoprotein A-I and hepatic lipase genes, primarily reflective of altered lipoprotein metabolism, play an important role in the establishment of recurrent coronary event risk in obese, nondiabetic postinfarction patients. These findings suggest close monitoring and consideration of weight reduction for obese postinfarction patients with elevated Lp(a) levels.

Abstract
A priority in preventive cardiology is to reduce the number of recurrent events and to prolong survival in patients with established coronary heart disease (CHD). Aim of the present study was to examine risk factors for long-term mortality in CHD patients who entered routine secondary prevention after a coronary event or intervention. Such patients, from the EUROASPIRE (EUROpean Action on Secondary Prevention through Intervention to Reduce Events) I and II studies in the region of Münster, Germany, were followed over a mean period of 8.0 years up to the end of 2005. Patients were up to 70 years of age at baseline when they were interviewed and examined using standardised methods. Baseline examination was carried out at least 6 months and at a mean of 19.5 months after the coronary event or procedure. In 367 patients from EUROASPIRE I and 380 patients from EUROASPIRE II, a total of 125 deaths (16.7%) occurred during follow-up. Multivariate analyses, using Cox proportional hazards models, established diabetes mellitus and smoking as predictors for all-cause mortality with estimated hazard rate ratios (HRRs) of 2.24 (95% confidence interval (CI): 1.43-3.49) and 1.95 (95% CI: 1.23-3.10), respectively. Significant associations were found between diabetes mellitus and cardiovascular (HRR 2.36; 95% CI: 1.31-4.24) as well as CHD mortality (HRR 2.40; 95% CI: 1.25-4.59). Systolic blood pressure was significantly associated with increased cerebrovascular disease mortality (HRR 1.04; 95% CI: 1.01 and 1.08 for 1 mmHg increase). In conclusion, long-term mortality in coronary patients from routine secondary prevention is substantial. Diabetes mellitus and smoking represent key issues in patients with established CHD.

Abstract
BACKGROUND AND OBJECTIVE Most evidence on the efficacy of intensive preventive programs of secondary prevention of coronary diseases comes from Anglo-Saxon countries and effectiveness remains controversial. We have scarce information about the efficacy of these types of programs in Spain. In the present analysis we show the results of the ICAR (Intervención en la Comunidad de Alto Riesgo coronario) study, aimed to analyze the efficacy of an intensive preventive program primary care based in reducing the cardiovascular recurrences and mortality in patients with coronary heart disease. PATIENTS AND METHOD We designed a randomized clinical trial, multicenter and community based, which included 23 health care areas in Catalonia, Spain. We followed for 5 years 2 cohorts of patients with coronary heart disease, aged 30-80 years. The intervention group was quarterly examined by their general practitioner, who adjusted treatments to control their cardiovascular risk factors thoroughly and reinforced life style behaviours. In order to do that, patient's weight and blood pressure were determined in each visit and laboratory test carried out twice a year. Patients in the control group received the usual care. In order to analyze the effect of the intervention cardiovascular recurrences and mortality were registered. RESULTS We included 983 patients. Mean (standard deviation) age was 64 (10) and 74.5% were men. During the follow-up 235 patients suffered some non-fatal cardiovascular recurrence (109 vs 126 in the control and intervention group, respectively; p = 0.84), and 45 died from cardiovascular recurrences (23 vs 22, respectively; p = 0.57). Adjusted hazard ratio of cardiovascular event and total mortality, for the intervention group were 1.01 (95% confidence interval, 0.74-1.39), and 0.92 (95% confidence interval, 0.54-1.56), respectively. CONCLUSIONS The implementation of an intensive secondary prevention program based on periodical reminds to patients with stable coronary heart disease to attend their general practitioners did not reduce either the cardiovascular recurrences or mortality at 5 years as compared with usual care.
