Abstract

Abstract Chili peppers are rich in capsaicin. The potent vasodilator calcitonin gene-related peptide (CGRP) is stored in a population of C-fiber afferents that are sensitive to capsaicin. CGRP and peptides released from cardiac C fibers have a beneficial effect in myocardial ischemia and reperfusion. It has been reported that capsaicin pretreatment deplete cardiac C-fiber peptide stores. Furthermore, it has also been reported that capsaicin-treated pigs significantly increase mean arterial blood pressure compared with controls and that the decrease in CGRP synthesis and release contributes to the elevated blood pressure. It has also been reported that sub-clinical hypothyroidism is associated with a significant risk of coronary heart disease (CHD). We present a case of arterial hypertensive crisis and acute myocardial infarction in a 59-year-old Italian man with high levels of thyroid stimulating hormone and with an abundant ingestion of peppers and of chili peppers which occurred the day before.
