Abstract

To define the clinical characteristics, prognosis and treatment of myocardial infarction (MI) in the elderly, we retrospectively compared the files of 101 patients aged > or = 75 years (mean: 82 +/- 4 years) and of 120 others aged < or = 65 years (mean: 55 +/- 4.7 years). The figures corresponding to younger patients are presented in brackets. The elderly group included 60.4% women (5%: p < 0.001), 58.9% hypertensive subjects (38.3%: p = 0.005); 30.4% diabetics (11.7%: p = 0.0013) and 12.6% smokers (66.1%: p < 0.001); 20.8% of the elderly had a history of MI (10%: p = 0.002), 15.8% of arteriopathy of the lower limbs (8.3%: p = 0.001) and 6.9% of cerebrovascular accident (1.7%: p = 0.02). Elderly patients were admitted after an average of 26.6 hours (10.4 hours: p < 0.001). Only 56.4% (79.2%) reported typical MI pain, 22.8% (7.5%) had a painless form, 31.8% (4.2%) an initial left ventricular failure, 21.8% (7.5%) a global cardiac dysfunction and 20.8% (4.2%) a cardiogenic shock (p < 0.001 for all comparisons). 63.4% had an anterior MI (40.8%: p < 0.001), 40.6% a Q-form (29.6%: p = NS) and 22.2% an atrial fibrillation (0.8%: p < 0.001). Serum myoglobin and total CK concentrations were significantly lower in elderly subjects. 20.8...Continue Reading

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Cardiogenic Shock

Cardiogenic shock is a devastating consequence of acute myocardial infarction and is associated with an extremely high mortality. Here is the latest research.

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.

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.

Aphasia

Aphasia affects the ability to process language, including formulation and comprehension of language and speech, as well as the ability to read or write. Here is the latest research on aphasia.
