[PMID: 38286569 PMCID: PMC10826564 DOI: 10.1136/openhrt-2023-002281] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Accepted: 10/31/2023] [Indexed: 01/31/2024] Open
Abstract
OBJECTIVES This study aimed to perform a meta-analysis of the short-term impact of ischaemic postconditioning (IPoC) on myocardial injury in ST elevation myocardial infarction (STEMI) using surrogate cardiac biomarkers. METHODS Eligible studies were identified using several article databases. Randomised controlled trials published between 1 January 2000 and 1 December 2021 comparing IPoC to standard of therapy in STEMI patients were included in the search. Outcomes included surrogates of myocardial injury, specifically peak troponin, creatine-kinase (CK) and CK myoglobin binding (CK-MB) enzyme levels. RESULTS 11 articles involving 1273 patients reported on CK-MB and 8 studies involving 505 patients reported on CK. Few studies used troponin as an outcome, thus, a subanalysis of troponin dynamics was not performed. Meta-regression analysis demonstrated no significant effect of IPoC on peak CK-MB (effect size -0.41, 95% CI -1.15 to 0.34) or peak CK (effect size -0.42, 95% CI -1.20 to 0.36). Linear regression analysis demonstrated a significant correlation between a history of smoking and CK-MB in the IPoC group (p=0.038). CONCLUSIONS IPoC does not seem to protect against myocardial injury in STEMI, except possibly in smokers. These results resonate with some studies using imaging techniques to ascertain myocardial damage. More research using troponin and cardiac imaging should be pursued to better assess the effects of IPoC on cardiovascular outcomes in STEMI.

Trends and predictions of metabolic risk factors for acute myocardial infarction: findings from a multiethnic nationwide cohort. THE LANCET REGIONAL HEALTH. WESTERN PACIFIC 2023; 37:100803. [PMID: 37693863 PMCID: PMC10485675 DOI: 10.1016/j.lanwpc.2023.100803] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 04/21/2023] [Accepted: 05/14/2023] [Indexed: 09/12/2023]
Abstract
Background Understanding the trajectories of metabolic risk factors for acute myocardial infarction (AMI) is necessary for healthcare policymaking. We estimated future projections of the incidence of metabolic diseases in a multi-ethnic population with AMI. Methods The incidence and mortality contributed by metabolic risk factors in the population with AMI (diabetes mellitus [T2DM], hypertension, hyperlipidemia, overweight/obesity, active/previous smokers) were projected up to year 2050, using linear and Poisson regression models based on the Singapore Myocardial Infarction Registry from 2007 to 2018. Forecast analysis was stratified based on age, sex and ethnicity. Findings From 2025 to 2050, the incidence of AMI is predicted to rise by 194.4% from 482 to 1418 per 100,000 population. The largest percentage increase in metabolic risk factors within the population with AMI is projected to be overweight/obesity (880.0% increase), followed by hypertension (248.7% increase), T2DM (215.7% increase), hyperlipidemia (205.0% increase), and active/previous smoking (164.8% increase). The number of AMI-related deaths is expected to increase by 294.7% in individuals with overweight/obesity, while mortality is predicted to decrease by 11.7% in hyperlipidemia, 29.9% in hypertension, 32.7% in T2DM and 49.6% in active/previous smokers, from 2025 to 2050. Compared with Chinese individuals, Indian and Malay individuals bear a disproportionate burden of overweight/obesity incidence and AMI-related mortality. Interpretation The incidence of AMI is projected to continue rising in the coming decades. Overweight/obesity will emerge as fastest-growing metabolic risk factor and the leading risk factor for AMI-related mortality.

Reperfusion Delays and Outcomes Among Patients With ST-Segment-Elevation Myocardial Infarction With and Without Cardiogenic Shock. Circ Cardiovasc Interv 2023; 16:e012810. [PMID: 37339233 DOI: 10.1161/circinterventions.122.012810] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Accepted: 04/18/2023] [Indexed: 06/22/2023]
Abstract
BACKGROUND Mortality remains high in patients with ST-segment-elevation myocardial infarction (STEMI) complicated by cardiogenic shock (CS), and early reperfusion has been shown to improve outcomes. We analyzed the association between first medical contact (FMC)-to-percutaneous coronary angiography time with mortality and major adverse cardiovascular events among patients with STEMI with and without CS. METHODS We performed a retrospective analysis of the Vancouver Coastal Health Authority STEMI registry, including all patients with STEMI who received primary percutaneous coronary angiography between January 1, 2010, and December 31, 2020, and stratified them by presence or absence of CS at hospital arrival. The primary outcome was in-hospital mortality, the secondary outcome was in-hospital major adverse cardiovascular events, defined as a composite of the first occurrence of mortality, cardiac arrest, heart failure, intracerebral hemorrhage, cerebrovascular accident, or reinfarction. Mixed effects logistic regression with restricted cubic splines was used to estimate the relationships between FMC-to-device time and the outcomes in the CS and non-CS groups. RESULTS 2929 patients were included, 9.4% (n=275) had CS. Median FMC-to-device time was 113.5 (interquartile range, 93.0-145.0) and 103.0 (interquartile range, 85.0-130.0) minutes for patients with CS and without CS, respectively. More patients with CS had FMC-to-device times above guideline recommendations (76.6% versus 54.1%, P<0.001). Between 60 and 90 minutes, for each 10-minute increase in FMC-to-device time, absolute mortality for patients with CS increased by 4% to 7%, whereas for patients without CS, it increased by <0.5%. CONCLUSIONS Among patients with STEMI undergoing primary percutaneous coronary angiography, reperfusion delays among patients with CS are associated with significantly worse outcomes. Strategies to reduce FMC-to-device times for patients with STEMI presenting with CS are required.

Abstract
Although substantial progress has been made in the diagnosis and treatment of acute coronary syndromes, cardiovascular disease remains the leading cause of death globally, with nearly half of these deaths due to ischaemic heart disease. The broadening availability of high-sensitivity troponin assays has allowed for rapid rule-out algorithms in patients with suspected non-ST-segment elevated myocardial infarction (NSTEMI). Dual antiplatelet therapy is recommended for 12 months following an acute coronary syndrome in most patients, and additional secondary prevention measures including intensive lipid-lowering therapy (LDL-C <1·4 mmol/L), neurohormonal agents, and lifestyle modification, are crucial. The scientific evidence for diagnosis and management of acute coronary syndromes continues to evolve rapidly, including adapting to the COVID-19 pandemic, which has impacted all aspects of care. This Seminar provides a clinically relevant overview of the pathobiology, diagnosis, and management of acute coronary syndromes, and describes key scientific advances.

Abstract
BACKGROUND The delay of percutaneous coronary intervention increases the risk of heart failure and mortality in STEMI. The aim of this study was to examine the time intervals of EMS and the factors associated with the time delay to angiography in patients with STEMI. METHODS The present study was conducted in Northern Ostrobothnia, Finland in 2014-2016. All patients transported to the hospital by EMS who were diagnosed with STEMI and underwent a primary angiography within 24 h of arrival were included. Angiography was defined as delayed if it was performed over 120 min of the first medical contact (FMC). RESULTS 310 patients met the inclusion criteria during the study period. Time from the FMC to angiography was less than 120 min in 231 patients (74.5%). In multivariate analysis, the factors associated with delayed angiography were the absence of chest pain (OR 2.46 (1.18-5.13),p = 0.016), dyspnea (OR 3.11 (1.54-6.28),p = 0.002), the treatment protocol violations by EMS (OR 2.41 (0.99-5.80),p = 0.050), treatment initiation at a primary health care center (OR 3.64 (1.39-9.48),p = 0.008), and the distance to hospital of over 100 km (OR 11.87 (6.14-22.93),p < 0.001). CONCLUSION In our study, treatment protocol violations, non-specific symptoms, and the distance to hospital of over 100 km were associated with primary angiography in patients with STEMI transported to the hospital by EMS.

Abstract
We evaluated the association between early coronary angiography (CAG) and outcomes in resuscitated out-of-hospital cardiac arrest (OHCA) patients, by linking data from the Singapore Pan-Asian Resuscitation Outcomes Study, with a national registry of cardiac procedures. The 30-day survival and neurological outcome were compared between patients undergoing early CAG (within 1-calender day), versus patients not undergoing early CAG. Inverse probability weighted estimates (IPWE) adjusted for non-randomized CAG. Of 976 resuscitated OHCA patients of cardiac etiology between 2011–2015 (mean(SD) age 64(13) years, 73.7% males), 337 (34.5%) underwent early CAG, of whom, 230 (68.2%) underwent PCI. Those who underwent early CAG were significantly younger (60(12) vs. 66(14) years old), healthier (42% vs. 59% with heart disease; 29% vs. 44% with diabetes), more likely males (86% vs. 67%), and presented with shockable rhythms (69% vs. 36%), compared with those who did not. Early CAG with PCI was associated with better survival and neurological outcome (adjusted odds ratio 1.91 and 1.82 respectively), findings robust to IPWE adjustment. The rates of bleeding and stroke were similar. CAG with PCI within 24 h was associated with improved clinical outcomes after OHCA, without increasing complications. Further studies are required to identify the characteristics of patients who would benefit most from this invasive strategy.

Impact of limited English proficiency on presentation and clinical outcomes of patients undergoing primary percutaneous coronary intervention. EUROPEAN HEART JOURNAL. QUALITY OF CARE & CLINICAL OUTCOMES 2021; 6:254-262. [PMID: 31782766 DOI: 10.1093/ehjqcco/qcz061] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 08/25/2019] [Revised: 11/06/2019] [Accepted: 11/26/2019] [Indexed: 11/13/2022]
Abstract
AIMS To evaluate the association of limited English proficiency (LEP) with reperfusion times and outcomes in patients undergoing primary percutaneous coronary intervention (PPCI) for ST-elevation myocardial infarction (STEMI). METHODS AND RESULTS This cohort study included 5385 patients who underwent PPCI in 2013-2017 and were prospectively enrolled in the Victorian Cardiac Outcomes Registry. Data linkage to government administrative datasets was performed to identify patients' preferred spoken language, socioeconomic status, and ambulance utilization data. Patients who had a preferred spoken language other than English were defined as having LEP. Of the study cohort, 430 patients (8.0%) had LEP. They had longer mean symptom-to-door time (STDT) [164 (95% confidence interval, CI 149-181) vs. 136 (95% CI 132-140) min, P < 0.001] but similar mean door-to-balloon time [79 (95% CI 72-87) vs. 76 (95% CI 74-78) min, P = 0.41]. They also had higher major adverse cardiovascular and cerebrovascular events (MACCE; 13.5% vs. 9.9%; P = 0.02), severe left ventricular dysfunction (11.0% vs. 8.4%, P = 0.02), and heart failure (HF) hospitalizations within 30 days of PPCI (5.1% vs. 2.0%, P < 0.001). On multivariable analysis, LEP did not independently predict 30-day MACCE [odds ratio (OR) 1.16, 95% CI 0.79-1.69; P = 0.45] but was an independent predictor of both prolonged STDT ≥ 120 min (OR 1.25, 95% CI 1.02-1.52; P = 0.03) and 30-day HF hospitalizations (OR 2.01, 95% CI 1.21-3.36; P = 0.008). CONCLUSION Patients with LEP undergoing PPCI present later and are more likely to have HF readmissions within 30 days of percutaneous coronary intervention, but with similar short-term MACCE. More effort to provide education in varied languages on early presentation in STEMI is required.

Abstract
Purpose To describe the inception and structure of the SingHealth Diabetes Registry (SDR) as well as the methodology used to set up the registry. The SDR was established to facilitate systematic and standardized data collection for diabetes mellitus within Singapore Health Services (SingHealth), which is an Academic Medical Center (AMC) and Singapore's largest group of healthcare institutions. The diabetes casemix and outcome variables within the registry cohort are also provided. Materials and Methods The SDR is built from SingHealth's electronic medical records (EMR) and clinical databases. It covers all individuals aged 18 and above with diabetes mellitus, excluding those with pre-diabetes. Cases are annually ascertained using criteria that include diagnosis codes, prescription records and laboratory test records. Data collection of casemix and outcome variables for the period 2013 to 2019 is complete. Results The SDR stands at 208,102 ascertained individuals, distributed across 8 healthcare sites within the AMC. The cohort is broadly reflective of the local gender and ethnic compositions but has a high proportion of older individuals with a mean age of 65.8 ± 13.7 years. Majority (>99%) have type 2 diabetes mellitus, with multiple other comorbidities (hypertension 84.1%, hyperlipidemia 86.2%, established cardiovascular disease 34.1%). At present, majority of individuals are able to meet key process indicators and 52.7% have a mean HbA1c of <7% (53 mmol/mol). Areas of potential improvement include increasing eye and foot screening rates, as well as glycemic control for the 19.5% of individuals with mean HbA1c >8% (64 mmol/mol). Conclusion The SDR is a large-scale, comprehensive, and representative diabetes registry that incorporates EMR data across the primary and hospital-based care continuum, in a major AMC in Singapore. The SDR has identified areas of improvement in diabetes processes and outcomes. It will support future quality assessment and improvements in diabetes care.

Abstract
RATIONALE Postconditioning at the time of primary percutaneous coronary intervention (PCI) for ST-segment-elevation myocardial infarction may reduce infarct size and improve myocardial salvage. However, clinical trials have shown inconsistent benefit. OBJECTIVE We performed the first National Heart, Lung, and Blood Institute-sponsored trial of postconditioning in the United States using strict enrollment criteria to optimize the early benefits of postconditioning and assess its long-term effects on left ventricular (LV) function. METHODS AND RESULTS We randomized 122 ST-segment-elevation myocardial infarction patients to postconditioning (4, 30 seconds PTCA [percutaneous transluminal coronary angioplasty] inflations/deflations)+PCI (n=65) versus routine PCI (n=57). All subjects had an occluded major epicardial artery (thrombolysis in myocardial infarction=0) with ischemic times between 1 and 6 hours with no evidence of preinfarction angina or collateral blood flow. Cardiac magnetic resonance imaging measured at 2 days post-PCI showed no difference between the postconditioning group and control in regards to infarct size (22.5±14.5 versus 24.0±18.5 g), myocardial salvage index (30.3±15.6% versus 31.5±23.6%), or mean LV ejection fraction. Magnetic resonance imaging at 12 months showed a significant recovery of LV ejection fraction in both groups (61.0±11.4% and 61.4±9.1%; P<0.01). Subjects randomized to postconditioning experienced more favorable remodeling over 1 year (LV end-diastolic volume =157±34 to 150±38 mL) compared with the control group (157±40 to 165±45 mL; P<0.03) and reduced microvascular obstruction ( P=0.05) on baseline magnetic resonance imaging and significantly less adverse LV remodeling compared with control subjects with microvascular obstruction ( P<0.05). No significant adverse events were associated with the postconditioning protocol and all patients but one (hemorrhagic stroke) survived through 1 year of follow-up. CONCLUSIONS We found no early benefit of postconditioning on infarct size, myocardial salvage index, and LV function compared with routine PCI. However, postconditioning was associated with improved LV remodeling at 1 year of follow-up, especially in subjects with microvascular obstruction.

The Impact of Out-of-Hours Presentation on Clinical Outcomes in ST-Elevation Myocardial Infarction. Heart Lung Circ 2019; 29:814-823. [PMID: 31262617 DOI: 10.1016/j.hlc.2019.05.184] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2018] [Revised: 03/26/2019] [Accepted: 05/01/2019] [Indexed: 10/26/2022]
Abstract
BACKGROUND Systems of care have been established to ensure patients with ST-elevation myocardial infarction (STEMI) get timely access to primary percutaneous coronary intervention (PPCI). In this study, we evaluated whether patients undergoing PPCI both in-hours and out-of-hours experience similar care and clinical outcomes. METHODS Of 9,865 patients who underwent PCI for STEMI from 2005 to 2016 and were enrolled in the multi-centre Melbourne Interventional Group registry, patients who had initially presented to a non-PCI capable hospital, received thrombolysis or presented >12hourspost-symptom onset were excluded. Our final study cohort of 4,590 patients were dichotomised by whether PPCI was performed in-hours or out-of-hours, and compared. The primary outcome was 30-day mortality. RESULTS The in-hours group included 1,865 patients (40.6%) while 2,725 patients (59.4%) had out-of-hours PPCI. Patients presenting out-of-hours had longer median door-to-balloon time (DTBT; 83 [IQR 61-109] vs. 60 [IQR 41-88] mins, p<0.01) and were more likely to receive a drug-eluting stent (p=0.001). Procedural characteristics were otherwise similar although rates of radial access were low overall (18.4%). No differences in in-hospital, 30-day or 12-month mortality were observed between the groups (p=NS). On Cox proportional hazards modelling, out-of-hours presentation was not an independent predictor of 30-day mortality (HR 0.94, 95% CI 0.71-1.22). A landmark analysis of data from 2012 did not change the primary outcome. CONCLUSION Despite a slightly longer DTBT, patients undergoing PPCI out-of-hours experienced similar care and clinical outcomes to the in-hours group. Given the majority of patients with STEMI present out-of-hours, these data have implications for STEMI systems of care.

Sex Differences in 1-Year Rehospitalization for Heart Failure and Myocardial Infarction After Primary Percutaneous Coronary Intervention. Am J Cardiol 2019; 123:1935-1940. [PMID: 30979413 DOI: 10.1016/j.amjcard.2019.03.021] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2018] [Revised: 03/01/2019] [Accepted: 03/05/2019] [Indexed: 10/27/2022]
Abstract
It is unclear whether universal access to primary percutaneous coronary intervention (pPCI) may reduce sex differences in 1-year rehospitalization for heart failure (HF) and myocardial infarction (MI) after ST-elevation myocardial infarction (STEMI). We studied 7,597 consecutive STEMI patients (13.8% women, n = 1,045) who underwent pPCI from January 2007 to December 2013. Cox regression models adjusted for competing risk from death were used to assess sex differences in rehospitalization for HF and MI within 1 year from discharge. Compared with men, women were older (median age 67.6 vs 56.0 years, p < 0.001) with higher prevalence of co-morbidities and multivessel disease. Women had longer median door-to-balloon time (76 vs 66 minutes, p < 0.001) and were less likely to receive drug-eluting stents (19.5% vs 24.1%, p = 0.001). Of the medications prescribed at discharge, fewer women received aspirin (95.8% vs 97.6%, p = 0.002) and P2Y12 antagonists (97.6% vs 98.5%, p = 0.039), but there were no significant sex differences in other discharge medications. After adjusting for differences in baseline characteristics and treatment, sex differences in risk of rehospitalization for HF attenuated (hazard ratio [HR] 1.05, 95% confidence interval [CI] 0.79 to 1.40), but persisted for MI (HR 1.68, 95% CI 1.22 to 2.33), with greater disparity in patients aged ≥60 years (HR 1.83, 95% CI 1.18 to 2.85) than those aged <60 years (HR 1.45, 95% CI 0.84 to 2.50). In conclusion, in a setting of universal access to pPCI, the adjusted risk of 1-year rehospitalization for HF was similar in both sexes, but women had significantly higher adjusted risk of 1-year rehospitalization for MI, especially older women.
