BACKGROUND: Recent reports suggest that early repolarization, a common electrocardiographic (ECG) pattern that has been always considered benign, could be a substrate for ventricular arrhythmias and sudden cardiac arrest. METHODS: We examined the associations between early repolarization and markers of ventricular arrhythmogenesis as defined by presence of ventricular late potentials ...

Heart Rate Turbulence in Post-MI Patients With DM. Background: Previous studies have described the clinical utility of heart rate turbulence (HRT) as an autonomic predictor in risk-stratifying patients after myocardial infarction (MI). Some reports showed that diabetes mellitus (DM) affects the prognostic value of autonomic markers. We assessed the utility of HRT ...

The prognostic role of specific biomarkers of the renin-angiotensin-aldosterone system and sympathetic activation pathways in heart failure has never been investigated in populations with current evidence-weighted treatment. To establish whether the plasma renin activity (PRA), among several neurohormonal biomarkers, is able to predict cardiac events in a population of patients ...

Despite the use of statin therapy and achieving the target for low-density lipoprotein cholesterol, a substantial number of coronary events are not prevented, and residual risk factors remain unsettled. Recently, ezetimibe has been shown to reduce not only low-density lipoprotein cholesterol but also triglyceride (TG) levels. The aim of this ...

Primary percutaneous coronary intervention is the preferred reperfusion therapy for ST-segment elevation acute myocardial infarction patients within 12 hours of symptom-onset. Routine stent implantation during the procedure significantly reduces the rate of target vessel revascularization, although restenosis still represents a current limitation of the technique. Drug-eluting stents were developed to ...

OBJECTIVES: To evaluate the cost-effectiveness of alternative approaches to revascularization for patients with 3-vessel or left main coronary artery disease (CAD). BACKGROUND: Previous studies have demonstrated that, despite higher initial costs, long-term costs with bypass surgery (CABG) in multivessel CAD are similar to those for percutaneous coronary intervention (PCI). The ...

BACKGROUND: In the prospective randomized TRIAS pilot study, the bio-engineered Genous™ endothelial progenitor cell capturing stent was compared with the Taxus Liberté(TM) -SR paclitaxel-eluting stent. At 1 year, a statistically non-significant difference in the rates of target vessel failure (cardiac death, myocardial infarction, or target vessel revascularization) was observed. We ...

Complex fractionated atrial electrograms (CFAE) are morphologically more uniform in persistent longstanding as compared with paroxysmal atrial fibrillation (AF). It was hypothesized that this may result from a greater degree of repetitiveness in CFAE patterns at disparate left atrial (LA) sites in longstanding AF. CFAEs were obtained from recording sites ...

Cardiac resynchronization therapy is a key non-pharmacological treatment strategy for drug-refractory moderate-to-severe symptomatic heart failure in the presence of compromised left ventricular function and ventricular conduction delay. Because not all patients with conventional criteria benefit from CRT, continuous efforts have been directed toward improving patient selection; in particular, emerging echocardiographic ...

The causes of coronary microvascular dysfunction (CMVD) in patients with cardiac syndrome X (CSX) are largely unknown. Common cardiovascular risk factors (CVRFs) and increased markers of inflammation have been associated with CMVD in some studies, but their role in determining CMVD in CSX patients remains poorly known. We studied 71 ...

Population-based studies indicate the risk of acute myocardial infarction (AMI) is greatest in the morning, during the initial hours of diurnal activity. The aim of this pilot study was to determine whether chronotype, i.e., morningness and eveningness, impacts AMI onset time. The sample comprised 63 morning- and 40 evening-type patients ...

Myocardial ischemia is a strong trigger of B-type natriuretic peptide (BNP) release. As ischemia precedes necrosis in acute myocardial infarction, we hypothesized that BNP might be useful in the early diagnosis and risk stratification of patients with acute chest pain. In a prospective, international multicenter study, BNP was measured in ...

Aims: The relationship between stent design and periprocedural myocardial infarction is unclear. The newest type of drug-eluting stent (DES), the everolimus-eluting stent (EES), has thinner strut and polymer thickness and a small amount of drug. EES use, therefore, could be related to less myocardial necrosis post-percutaneous coronary intervention (PCI). This ...

Proton pump inhibitors (PPIs) are usually prescribed to patients undergoing dual antiplatelet therapy to decrease the risk of gastrointestinal bleeding. Recent studies have raised concerns that PPIs could reduce clopidogrel's efficacy by competitive inhibition of cytochrome P450 2C19 isoenzyme. All PPIs are metabolized by cytochrome P450 2C19, although to varying ...

Thymic infarcts are rare, and mainly occur following an occlusive event of stromal vessels. Distinguishing thymic infarcts from anterior mediastinal masses is important due to different treatment plans and prognoses. We describe an unusual case of a thymic infarct in a patient with the sudden onset of chest pain. In ...

Evidence obtained in multiple experimental models has revealed that cardiac 'conditioning' strategies - including ischaemic preconditioning, postconditioning, remote conditioning and administration of pharmacological conditioning mimetics - are profoundly protective and significantly attenuate myocardial ischaemia-reperfusion injury. As a result, there is considerable interest in translating these cardioprotective paradigms from the laboratory ...
