Title: Response of coronary circulation to cutaneous cold
Abstract: The coronary and systemic hemodynamic responses to cutaneous cold stimulation were investigated in 25 patients. Nineteen had coronary heart disease and six had no evidence of coronary heart disease. Cutaneous cold increased systemic arterial and left ventricular end-diastolic blood pressures. Coronary blood flow increased in proportion to the increase in myocardial oxygen consumption, and there was no significant change in coronary blood arteriovenous oxygen difference. Cold provoked angina pectoris in five patients and chemical evidence of myocardial hypoxia in seven patients. We detected no difference in systemic or coronary circulatory responses in patients with a history of cold intolerance, and myocardial hypóxia appeared to be related to restricted coronary reserve rather than to a special effect of cold on myocardial metabolism or coronary vasomotion.
