Multi-vessel coronary artery disease (CAD) is associated with worse outcome in non-ST segment elevation myocardial infarction (NSTEMI) patients. Depending on the severity of CAD, there may be prolongation of atrial depolarization time as a result of left ventricular dysfunction and atrial ischemia. Therefore, we aimed to study whether the severity of CAD can be predicted with the P wave peak time (PWPT) in the electrocardiography (ECG) obtained during the diagnosis in NSTEMI patients.

The aim of this study was to compare the relationship between a novel electrocardiographic (ECG) parameter P wave peak time (PWPT) and classic P wave parameters with atrial fibrillation (AF).
Prolongation of the interval from the peak to the end of the T wave (Tp-Te) on a 12-lead electrocardiogram (ECG) is associated with ventricular arrhythmias. The aim of this study was to clarify associ...
Prolonged dual antiplatelet therapy (DAPT) requires consideration of both reduced thrombotic events and increased bleeding risk. The associated subtle balance between the benefits and harms depends up...
The management of patients with carotid stenosis and symptomatic coronary artery disease (CAD) is challenging. This study assessed the impact of clinical coronary disease severity on carotid endartere...
Recent prospective studies have identified distinct plasma ceramides as strong predictors of major adverse cardiovascular events in patients with established or suspected coronary artery disease (CAD)...
The purpose of this study is to measure T-Wave Alternans (TWA) in patients with acute coronary syndrome. Researchers are blinded to clinical TWA measurements. The investigators will then...
T-wave alternans is a test that looks at microvolt changes in the T-wave on a beat to beat basis. The presence or absence of such changes has been shown to predict or exclude future arrhy...
Coronary heart disease (CHD) is a public health care challenge. There are three types of treatment for CHD, medication, percutaneous coronary intervention (PCI) and coronary artery bypass ...
A study comparing the pharmacokinetics of prolonged-release melatonin versus standard, immediate-release melatonin. Multiple blood draws over a 10-hour period will be analysed to determine...
Aortic valve pathology is the third most common cardiovascular disease after coronary artery disease and hypertension, which is responsible for severe morbidity and mortality in elderly pa...
Group of hemorrhagic disorders in which the VON WILLEBRAND FACTOR is either quantitatively or qualitatively abnormal. They are usually inherited as an autosomal dominant trait though rare kindreds are autosomal recessive. Symptoms vary depending on severity and disease type but may include prolonged bleeding time, deficiency of factor VIII, and impaired platelet adhesion.
Abnormal balloon- or sac-like dilatation in the wall of CORONARY VESSELS. Most coronary aneurysms are due to CORONARY ATHEROSCLEROSIS, and the rest are due to inflammatory diseases, such as KAWASAKI DISEASE.
Malformations of CORONARY VESSELS, either arteries or veins. Included are anomalous origins of coronary arteries; ARTERIOVENOUS FISTULA; CORONARY ANEURYSM; MYOCARDIAL BRIDGING; and others.
Complete blockage of blood flow through one of the CORONARY ARTERIES, usually from CORONARY ATHEROSCLEROSIS.
Prolonged dysfunction of the myocardium after a brief episode of severe ischemia, with gradual return of contractile activity. It occurs frequently, both in the experimental laboratory and in clinical medicine. Since stunned myocardium occurs adjacent to necrotic tissue after prolonged coronary occlusion, many myocardial infarcts may be a mixture of necrotic and stunned tissue.
