Pain in the Marriage

Stage A 78-year-old man had retrosternal and left thoracic pressure-like pain that developed gradually over a four-hour period. He had never had similar symptoms before. Shortness of breath and lassitude began shortly before he was hospitalized. Response These symptoms are compatible with unstable angina. A ruptured atheromatous plaque with the formation of a thrombus in a coronary vessel is the characteristic pathogenic mechanism, with subsequent myocardial ischemia. Tachyarrhythmias or bradyarrhythmias can also cause a predisposition to myocardial oxygen insufficiency in the presence of a preexisting atheromatous narrowing of a coronary vessel. I would like to know more about predisposing factors . . .
