Abstract

Over a 3-year period, we performed 232 consecutive percutaneous transluminal coronary angioplasty (PTCA) procedures in 171 patients, 132 (77%) of whom were men and 39 (23%) of whom were women. The patients' ages ranged from 26 to 85 years (average, 56.5 years). All of the patients had symptoms of coronary insufficiency, manifested by stable angina in 106 cases, unstable angina in 44 cases, post myocardial infarction angina in 19 cases, arrhythmia in 1 case, and syncope in 1 case. All PTCA dilatations were done by the same operators, using the same technique. The procedures were categorized as follows: Group 1 included 157 single-vessel PTCA procedures, which had a success rate of 87.3%; these included 52 dilatations of the right coronary artery (success rate, 84%), 94 dilatations of the left anterior descending artery (success rate, 86%), and 11 dilatations of the left circumflex system (success rate, 90%). Group 2 included 29 double-vessel PTCA procedures (58 total procedures), which had an 88% success rate, and group 3 comprised 17 vein-graft PTCAs, with an 86.9% success rate. Complications included coronary artery occlusion in 15 cases (9.0%), myocardial infarction in four cases (2.3%), and cardiac arrhythmia in one case (0....Continue Reading

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.
