Coronary artery spasm during exercise: treatment with verapamil.
Six patients who had documented coronary spasm and no coronary artery with organic obstruction greater than 50% developed angina and ST-segment elevation on exercise testing. Oral verapamil, 160-480 mg/day, prevented exercise-induced ischemia in all patients and increased maximal work capacity from 611+/- 250 kpm to 808 +/- 160 kpm (p less than 0.02). In two patients, a relationship between the...
متن کاملCoronary artery spasm during exercise in patients with variant angina.
Seven patients with typical variant angina without coronary stenoses greater than 50% developed angina and ST-segment elevation during treadmill exercise testing. In all cases the ST-segment elevation occurred in the same leads during exercise testing as during spontaneous attacks at rest. Five of the patients had developed spontaneous coronary spasm during coronary arteriography, in each case ...
متن کاملCoronary Artery Spasm During Dobutamine Stress Echocardiography: A Case Report
Dobutamine stress echocardiography (DSE) has been widely used as a diagnostic and prognostic modality in the management of stress. DSE is associated with limited complications and adverse effects on the health of patients. In this case report, we described a 42-year-old female patient with dobutamine-induced coronary artery spasm with history of exertional dyspnea, which had deteriorated recent...

was administered directly into the graft with complete relief of pain and resolution of ST segment elevation. Angiography of the graft (Fig. 2, C) now revealed the graft to be patent; there was normal distal runoff from the graft with a 75”; obstructive lesion of the native RCA just distal to the site of graft insertion. Subsequently, pain again developed associated with ST segment elevation. G...
متن کاملFatigue during intermittent-sprint exercise.
1. There is a reversible decline in force production by muscles when they are contracting at or near their maximum capacity. The task-dependent nature of fatigue means that the mechanisms of fatigue may differ between different types of contractions. This paper examines how fatigue manifests during whole-body, intermittent-sprint exercise and discusses the potential muscular and neural mechanis...
