BACKGROUND: Trials have shown superiority of primary percutaneous intervention (PPCI) over in-hospital thrombolysis in ST-elevation myocardial infarction (STEMI) patients treated within 6-12 hours from symptom onset. These studies also included high-risk patients not all of whom underwent a therapeutic intervention. OBJECTIVES: To compare the outcome of early-arriving stable STEMI patients treated by thrombolysis with or without coronary angiography to the outcome of PPCI-treated STEMI patients...

The contribution of prothrombotic genetic risk factors in the pathogenesis of premature acute myocardial infarction (MI) is controversial. We examined the prevalence of prothrombotic polymorphisms (G1691A of factor V gene [FV Leiden] and G20210A of prothrombin [FII] gene), deficiencies of natural anticoagulants (protein C, protein S and antithrombin III) and antiphospholipid syndrome (APS) in patients with early ST-segment elevation MI (STEMI). We recruited 255 consecutive patients who had survived a STEMI ≤ 35 years of age (224 men)...

BACKGROUND: Acute kidney injury (AKI) following primary percutaneous coronary intervention (pPCI) is frequently interpreted as contrast-induced AKI but may result from other insults. We aimed to determine the causal association of contrast material exposure and the incidence of AKI following pPCI using a control group of propensity score-matched patients with ST-segment-elevation myocardial infarction who were not exposed to contrast material. METHODS AND RESULTS: We studied 2025 patients with ST-segment-elevation myocardial infarction who underwent pPCI and 1025 patients receiving fibrinolysis or no reperfusion who were not exposed to contrast material during the first 72 hours of hospital stay (control group)...

BACKGROUND: Antihypertension medication (antihypertensive) adherence lowers risk of cardiovascular disease (CVD); few studies have examined this association among older adults. METHODS AND RESULTS: We assessed this association among Medicare fee-for-service beneficiaries aged 66 to 79 years who were newly diagnosed with hypertension and initiated on antihypertensives in 2008-2009 (n=155 597). We calculated proportion of days covered (PDC) during follow-up, using proportional subdistribution hazard models, to examine association between antihypertensive adherence and a composite CVD outcomes, including first incident of fatal/nonfatal acute myocardial infarction, ischemic heart disease, stroke/transient ischemic attack, and heart failure...

BACKGROUND: Our study aimed to compare three different percutaneous coronary intervention (PCI) approaches: culprit-only (COR) and complete (CR) revascularization - categorizing into immediate (ICR) or staged (SCR). METHODS: We searched 13 databases for randomized controlled trials. Articles were included if they compared at least two strategies. To have more studies in each analysis, an adjusted analysis was performed using person-years to incorporate follow-up durations and obtain pooled rate ratios (RR), with their corresponding 95% confidence interval...

INTRODUCTION: There is an expectation that with the adoption of more sensitive cardiac troponin (cTn) assays, unstable angina would become a rarity. However, recent data from the SWEDEHEART registry demonstrated that 15% of patients admitted with non ST-elevation acute coronary syndrome (NSTE-ACS) still were regarded having unstable angina. We aimed to further investigate the clinical characteristics and outcome of these patients. METHODS: Retrospective registry-based analysis (SWEDEHEART) including 3204 unstable patients, 18,194 non ST-elevation myocardial infarction (NSTEMI) patients and 977 controls without acute cardiovascular disease...

BACKGROUND: Previous studies have described the protective effects of DADLE on myocardial injury in sepsis. Recently, autophagy has been shown to be an innate defense mechanism in sepsis-related myocardial injury. However, whether DADLE has an pro-autophagic effect is yet to be elucidated. The present study aimed to investigate the effect of DADLE on the regulation of autophagy during sepsis. METHODS: Male mice were subjected to LPS or vehicle intraperitoneal injection...

Excessive alcohol consumption represents one of the main causes of non-ischemic dilated cardiomyopathy. Alcoholic cardiomyopathy is characterized by dilation and impaired contraction of one or both myocardial ventricles. It represents the final effect of alcohol-induced toxicity to the heart. Several pathophysiological mechanisms have been proposed at the basis of alcohol-induced damage, most of which are still object of research. Unfortunately, symptoms of alcoholic cardiomyopathy are not specific and common to other forms of heart failure and appear when dilatation and systolic dysfunction are consolidated...

BACKGROUND: The role of necroptosis in myocardial injury has not been fully characterized. Here we examined roles of mitochondrial permeability transition pore (mPTP) and autophagy in necroptosis of cardiomyocytes. METHODS AND RESULTS: In H9c2 cells, necroptosis was induced by treatment with TNF-α (TNF) and z-VAD-fmk (zVAD) for 24h, and necroptotic death was determined by LDH release (as % of total). TNF/zVAD increased LDH release from 16.6±4.3% to 60.6±2.7%, and the LDH release was suppressed by necrostatin-1 (29...

REVIEW
Meg M Sleeper
Gene therapy is a procedure resulting in the transfer of a gene into an individual's cells to treat a disease. One goal of gene transfer is to express a functional gene when the endogenous gene is inactive. However, because heart failure is a complex disease characterized by multiple abnormalities at the cellular level, an alternate gene delivery approach is to alter myocardial protein levels to improve function. This article discusses background information on gene delivery including packaging, administration, and a brief discussion of some of the candidate transgenes likely to alter the progression of naturally occurring heart disease in dogs and cats...

REVIEW
Kathryn M Meurs
Arrhythmogenic right ventricular cardiomyopathy is an inheritable form of myocardial disease characterized most commonly by ventricular tachycardias, syncope, and sometimes systolic dysfunction and heart failure. A genetic mutation in the striatin gene has been identified in many affected dogs. Dogs with only one copy of the mutation (heterozygous) have a variable prognosis with many dogs remaining asymptomatic or successfully managed on antiarrhythmic drugs for years. Dogs that are homozygous for the mutation seem to have a worse prognosis...
