Unstable angina and coronary angioplasty.

Of 2,122 consecutive patients undergoing elective coronary angioplasty from 1982 to 1985, 62% had stable angina pectoris (SAP), and 38% had unstable angina pectoris (UAP). There were differences between the two groups in clinical and morphological factors and in initial and late results of angioplasty. UAP patients were more likely than SAP patients to be smokers and to have had prior myocardial infarctions. Lesions in UAP patients were more severe, longer, more eccentric, more irregular, and more likely to have intracoronary thrombi than were lesions in SAP patients. Coronary angioplasty success was achieved in 84% of UAP and in 88% of SAP patients (p less than 0.05), and complications occurred in 6.7% of UAP and in 4.7% of SAP patients (p less than 0.05). Hospital death rates were low and similar, 0.2% for both groups. Follow-up (mean, 37 months) showed recurrent Canadian Cardiovascular Society (CCVS) class III/IV angina in 30.1% of UAP and in 25.2% of SAP patients (p less than 0.05). There was a return to work in 86% of UAP and in 91% of SAP patients (p less than 0.05). When UAP patients' durations of symptoms were further fractionated, it was found that the earlier angioplasty was performed after onset of angina, the lower was the success rate and the higher the complication rate and incidence of late follow-up untoward events. When coronary angioplasty was performed within 1 week of onset of angina ("early"), success was 79.1%; when angioplasty was performed 2 weeks or more after onset of angina ("later"), success was 86.3%. Major cardiac events occurred in 11.5% in the early group and in 4.8% in the later group (p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Atrioventricular block in accidental hypothermia--a case report.

The finding of second-degree and high-grade atrioventricular block in a patient with severe accidental hypothermia is described. Additional findings included atrial fibrillation, severe sinus bradycardia, and prominent J (Osborn) waves. This case represents, to the authors' knowledge, the first report of advanced spontaneous AV block not induced by atrial pacing in severe accidental hypothermia. Reversal of the block, and other characteristic changes, suggest a relationship to low temperature.

Sinus node suppression in acute strokes--case reports.

The authors report on 5 patients, 4 of them observed over a period of only two months in one community hospital, who developed profound sinus node suppression in the early phase following acute strokes. This complication resulted in the death of 2; in the remaining 3, it was controlled by electrical cardiac pacing or intravenous atropine. In 3 patients, the strokes were due to subarachnoid hemorrhage, and in 2, they were secondary to vascular occlusion. In at least 4 patients, the prognosis seemed favorable from a neurologic standpoint. Vagally mediated sinus node arrest may, therefore, represent a potentially fatal complication of strokes and may be more frequent than currently appreciated. Continuous monitoring in the early phase of acute strokes and pacemaker therapy may be lifesaving in some patients. This and the general phenomenon of functional failure of the sinus node due to a variety of causes are discussed.

Sustained ventricular tachycardia associated with influenza syndrome in a young girl--a case report.

Ventricular arrhythmias in children with no demonstrable heart disease are rare. In a thirteen-year-old girl, a typical influenza syndrome was complicated by sustained ventricular tachycardia. Exercise tests, echocardiography, electrophysiological studies, and endomyocardial biopsy were negative. Viremia, fever, or medications may be responsible for this unusual complication.

Iatrogenic left main coronary artery stenosis following PTCA or valve replacement.

We report three patients who developed iatrogenic severe left main coronary artery stenosis. In two, it was secondary to coronary cannulation during aortic valve replacement and in one it followed distention of the artery during balloon dilatation of a proximal lesion in the left anterior descending artery. In all three, the stenosis was clinically manifest a few months after the intervention. All were successfully treated by aortosaphenous coronary bypass. A common mechanism for the three cases may be mechanical distention of the left main coronary artery resulting in intimal damage with secondary fibrosis and stenosis. The percutaneous transluminal coronary angioplasty-related stenosis is, to our knowledge, the first reported case of this nature, and represents a previously unrecognized complication of this procedure.

Ruptured abdominal aortic aneurysms: experience with 70 cases.

During the period 1965-1983, 270 patients underwent resection of abdominal aortic aneurysm. In 70 patients (26%) the aneurysm was ruptured. Overall hospital mortality of patients with ruptures was 34%. Five patients died before the graft could be completed. Common denominators associated with mortality were hypotension, renal failure, cardiac arrest, and postoperative hemorrhage. The average age over the first 10 years was 68, but subsequently, has risen gradually, with a corresponding increase in mortality despite improved surgical technique and postoperative care. Only with more widespread elective resections and earlier diagnosis of rupture followed by prompt operative management, can the outlook for patients with abdominal aortic aneurysm be improved.
