Preliminary Pain in Coronary Thrombosis

Unstable Angina

“…However, this distinction began to blur in 1937, when Sampson and Eliaser 4 and Feil 5 described several patients with severe, prolonged anginal pain at rest that differed from stable angina but sometimes preceded AMI. This disorder was variously referred to as preinfarction angina or crescendo angina, and reflecting the belief that it was in a gray zone between stable angina and AMI, it was also called intermediate coronary syndrome.…”

Multiple Fresh Coronary Occlusions in Patients With Antecedent Shock

“…As pointed out in previous communications, collateral circu¬ lation generally has been found to develop only when and where it is needed, in regions where it is plausible to assume relative coronary insufficiency.1 Additional pathologic evidence indicative of diminished coronary blood flow is afforded by the presence of moderate to marked myocardial fibrosis in 6 of the 8 hearts and healed myocardial infarcts in 2 (table 1). 4. Antecedent Shock: It is commonly recognized that shock con¬ stitutes one of the most prominent clinical features of acute coronary arterial thrombosis.…”

Prodromata in Acute Myocardial Infarction

“…Estimates of t-he incidence of prodromata have ranged from 15 to 50%. [1][2][3][4][5][6][7][8] The present study is designed to evaluate the prevalence of prodromata in patients admitted to the hospital with a definitive diagnosis of acute myocardial infarction and to compare certain clinical findings in patients with and without historical evidence of prodromata.…”
