Abstract

The past literature has long ago identified painless myocardial infarction as a clinical entity; however, the term has been applied, often loosely, to denote diagnosis of infarction made at autopsy, or during routine electrocardiography, or at presentation with atypical symptoms. Many of the old studies were retrospective or included patients who could not contribute a reliable history. Systematic interviews of 517 consecutive patients with an acute myocardial infarction admitted to the Coronary Care Unit were carried out; a large array of data was collected prospectively while the patients were taken care of in the hospital. A reliable history of symptoms at the inception of the clinical episode could be provided by 501 patients; 40 patients (8.0%) presented with painless (not silent) infarction, while the remaining 461 had pain. Multivariate analysis revealed that painless presentation of myocardial infarction correlated positively with age (OR 1.05, CI 1.02-1.08) and admission Killip class (OR 2.58, CI 2.16-2.97), and negatively with history of prior angina (OR 0.16, CI 0.15-064); also it was not a predictor of increased rate of mortality or life-threatening arrhythmias. Presentation with painless myocardial infarction occur...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
