Coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) have been developed as revascularization techniques for coronary artery disease. CABG offers a survival advantage over medical therapy, especially for high-risk coronary patients, whereas PCI is the most frequent initial procedure to treat multi-vessel coronary artery disease, because it is ...

In acute coronary syndromes, C-reactive protein (CRP) strongly relates to subsequent death, but surprisingly not to recurrent myocardial infarction. Other biomarkers may reflect different processes related to these outcomes. We assessed 8 inflammatory and vascular biomarkers and the risk of death and recurrent nonfatal cardiovascular events in the 16 weeks ...

Syncope is generally benign but when it is due to an underlying cardiovascular condition, the prognosis can be guarded. Patients with syncope may be at risk of dying suddenly from a ventricular arrhythmia especially if the collapse is caused by a poorly-tolerated, self-terminating, ventricular tachycardia (VT). If a similar VT ...

Antioxidant vitamin (vitamin E, beta-carotene, and vitamin C) are widely used for preventing major cardiovascular outcomes. However, the effect of antioxidant vitamin on cardiovascular events remains unclear. We searched PubMed, EmBase, the Cochrane Central Register of Controlled Trials, and the proceedings of major conferences for relevant literature. Eligible studies were ...

Sudden cardiac death in athletes is a recurrent phenomenon at sporting events and during training. Recent studies have associated sudden cardiac death with such cardiovascular conditions as coronary artery anomalies, cardiomyopathies, and electrocardiographic abnormalities, most of which are screenable with modern imaging techniques. We recently inaugurated the Center for Coronary ...

Myocardial infarction (MI) is the most frequent diagnosis made in majority of sudden death cases subjected to clinical and medicolegal autopsies. When sudden death occurs at a very early stage of MI, traditional macroscopic examination, or histological stains cannot easily detect the myocardial changes. For this reason we propose a ...

Cardiomyocyte death is an important reason for the cardiac syndromes, such as heart failure (HF) and myocardial infarction (MI). In the heart diseases, necrosis is one of the main forms of cell death. MicroRNAs (miRNAs) are a class of small non-coding RNAs that mediate post-transcriptional gene silencing. Hitherto, it is ...

The majority of individuals with early repolarization (ER) patterns have a benign prognosis. However, recent case-control series and population studies have established a significant association between ER and an increased risk of arrhythmic death. There is a common agreement that J-waves, particularly of large amplitude, dynamic, and present in multiple ...

BACKGROUND: Normal myocardial perfusion imaging (MPI) indicates a low risk for cardiac death and new ischaemic events. However, the impact of normal MPI combined with a high coronary artery calcium score (CACS) is not clear. The aims of this study were to evaluate the risk of severely elevated CACS and ...

In patients on conventional heart failure therapy including angiotensin-converting enzyme (ACE) inhibitors, the addition of angiotensin receptor blockers (ARBs), direct renin inhibitors (DRIs), or aldosterone antagonists are therapeutic options to further reduce the risk of cardiovascular events. However, whether one is preferable over the other is not known. PubMed, EMBASE, ...

BACKGROUND: -Gp130 is the common signal-transducing receptor subunit of the IL-6 family, which may be involved in the progression of HF. We hypothesized that soluble gp130 (sgp130) would provide prognostic information beyond that of IL-6 in a heart failure (HF) population from the Controlled Rosuvastatin Multinational Trial in Heart Failure ...

Hypertrophic cardiomyopathy (HCM) occurs in 1 in every 500 individuals. It represents the most common cause of sudden cardiac death in those under the age of twenty-five. 3-5% patients with HCM go on to develop the dilated, hypokinetic end stage (ES) HCM with systolic failure. They have a higher incidence ...

Clinicians who diagnose and manage epilepsy frequently encounter diagnoses of a nonneurological nature, particularly when assessing patients with transient loss of consciousness (T-LOC). Among these, and perhaps the most important, is cardiac syncope. As a group, patients with cardiac syncope have the highest likelihood of subsequent sudden death, and yet, ...

BACKGROUND: Detecting myocardial ischemia in hemodialysis patients is crucial given the high incidence of silent ischemia and the high cardiovascular mortality rates. Abnormal myocardial fatty acid metabolism as determined by imaging with (123)I-labeled BMIPP (β-methyl iodophenyl-pentadecanoic acid) might be associated with cardiac-derived death in hemodialysis patients. STUDY DESIGN: Prospective observational ...

Amyloidosis is a disease characterized by abnormal deposition of amyloid protein within tissues throughout the body. The site of deposition can differ between patients, and therefore, clinical presentation can vary. Here, we present a case of previously undiagnosed amyloidosis presenting with sudden death. Autopsy demonstrated amyloid infiltration of intramural myocardial ...

Prolongations of PR interval and QRS duration on 12-lead electrocardiogram are associated with atrioventricular and interventricular/intraventricular dyssynchrony, respectively. However, their clinical significance remains unclear in real-world heart failure (HF) population. We assessed whether the presence of first-degree atrioventricular block and/or QRS prolongation (≥120 ms) is associated with worse short- and ...

Death from coronary artery disease is by far the leading cause of death worldwide. There is no doubt that a better understanding of atherothrombosis has guided development of improved diagnostic facilities as well as revascularization technologies in combination with current antithrombotic strategies that have altogether impressively reduced acute thromboembolic complications ...

The aim of this study was to determine whether left ventricular ejection fraction (LVEF) influences the relationship between abnormal myocardial sympathetic innervation imaging by iodine 123 meta-iodobenzylguanidine ((123)I-mIBG) and outcomes in patients with heart failure (HF). In systolic HF, both abnormal (123)I-mIBG imaging and reduced LVEF are associated with higher ...

Excess generation of reactive oxygen species (ROS) and cytosolic calcium accumulation play major roles in the initiation of programmed cell death during acute myocardial infarction. Cell death may include necrosis, apoptosis and autophagy, and combinations thereof. During ischemia, calcium handling between the sarcoplasmic reticulum and myofilament is disrupted and calcium ...
