Overview
Nocturnal angina is the occurrence of anginal discomfort either during the initial few hours of sleep or during the early morning hours. It is speculated that discomfort caused during the first hour of sleep is due to increased venous return, whereas the discomfort caused during the early morning hours is due to increased vascular tone.
Treatment
Medical Therapy
The treatment of nocturnal angina pectoris is same as the chronic stable angina. If increased coronary vascular tone is felt to be the underlying mechanism, the calcium channel blockade may be of benefit.
