Predisposing Factors in Sudden Cardiac Death

چکیده

In an epidemiologic study of the total population of Tecumseh, Michigan, 98 deaths from coronary heart disease were observed between 1959 and 1965. Forty-five of the fatalities occurred within 1 hour of the onset of symptoms and were classified as sudden. The proportion of sudden deaths among men was nearly twice that among women, and the incidence increased progressively with age in both sexes. Hypertensive heart disease, coronary heart disease, or diabetes mellitus had been detected on prior examination in 62% of those who died suddenly. Physiologic abnormalities associated with a high risk of coronary heart disease were also found more frequently than in the total Tecumseh population. All but seven of the persons who died suddenly had abnormalities including arrhythmias and conduction defects which were detected in the standard 12-lead electrocardiogram. Although sudden deaths often seem to occur without warning, the victims are predisposed by conditions which are detectable long before the catastrophic event. The identification of conditions which are precursors of sudden death from coronary heart disease permits a rational consideration of possible preventive measures.

Apical Hypertrophic Cardiomyopathy in a Case with Chest Pain and Family History of Sudden Cardiac Death: A Case Report

Hypertrophic cardiomyopathy (HCM) is the most common genetic cardiovascular disease, which is caused by a multitude of mutations in genes encoding proteins of the cardiac sarcomere (1). Apical hypertrophic cardiomyopathy (AHCM) is an uncommon type of HCM. The sudden cardiac death is less likely to occur in the patients inflicted with AHCM (2). Herein, we presented the case of a 29-year-old man ...

Histomorphological Spectrum of Various Cardiac Changes in Sudden Death: An Autopsy Study

Background and Objectives: In spite of large number of studies conducted so far, sudden cardiac death remains an enigma and relative importance of acute coronary events as a trigger of sudden death is currently unclear. An autopsy study of heart was therefore planned to observe various histomorphological cardiac changes, and to determine the frequency association of acute coronary events and my...

Sudden cardiac death in sport, although rare, but is a tragic event, attracting the media and public attention. Sport and exercise may act as a trigger for sudden cardiac death. Risk of sudden death in young athletes with cardiovascular disease is 2.5 times more frequent than non-athlete individuals. More than 90% of cases of sudden death occur during or immediately after training or competitio...

Echocardiographic risk factors predisposing to sudden cardiac death in hypertrophic cardiomyopathy.

I n patients with hypertrophic cardiomyopathy (HCM), the low positive predictive accuracy of the previously recognised risk factor for sudden death—that is, non-sustained ventricular tachycardia, syncope, abnormal blood pressure response to exercise, family history of sudden death, and massive left ventricular (LV) hypertrophy—is a major limitation. Patients with a combination of two or more su...

Sudden Cardiac Death, Genes, and Arrhythmogenesis

Malignant ventricular arrhythmias are the leading mechanism of death in patients with acute and chronic cardiac pathologies. The extent to which inherited mutations and polymorphic variation in genes determining arrhythmogenic mechanisms affect these patients remains unknown, but based on recent population studies, this risk appears significant, deserving much greater investigation. This report...
