Abstract

To analyze the clinic-pathologic features of elderly myocardial infarction patients (> 60 years) with and without left ventricular aneurysm formation. Between January 1980 and October 2009, 107 myocardial infarction patients were divided into aneurysm group (n = 31) and non-aneurysm group (n = 76) according to autopsy results and the clinic-pathologic features of the two groups were compared. Previous angina pectoris history was significantly less in aneurysm group than in non-aneurysm group [45.2% (14/31) vs. 92.1% (70/76), P = 0.047]. Incidence of hypertension was significantly higher in aneurysm group than in non-aneurysm group [77.4% (24/31) vs. 36.8% (28/76), P = 0.033]. The percentage of single-vessel disease [54.8% (17/31) vs. 23.7% (18/76), P = 0.033] and the LAD disease [96.8% (30/31) vs. 51.3% (39/76), P = 0.048] were both significantly higher in aneurysm group than in non-aneurysm group. Heart failure and ventricular arrhythmias were more likely the cause of death in patients with aneurysm than patients without aneurysm [56.3% (18/31) vs. 19.7% (15/76), P = 0.007]. Aneurysm mostly located in left ventricular anterior wall and apex. Our results suggest that patients with left ventricular aneurysm formation are more li...Continue Reading

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.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

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.
