We describe a patient with acute myocardial infarction, which was thought to result from plaque rupture or thrombosis because of coronary artery spasm. The vasospasm was most likely induced by stimulation of the α-adrenergic receptors during alternating heat exposure during sauna bathing and rapid cooling during cold water bathing. This report emphasizes the dangers of rapid cooling after sauna bathing in patients with coronary risk factors.

Objective —We assessed the reflection pressure wave using noninvasive measurement of wave intensity (WI) in patients with cardiomyopathy. Methods and results — Subjects included 8 patients with hypertrophic cardiomyopathy (HCM group) and 10 patients with dilated cardiomyopathy (DCM group).Twelve healthy subjects were used as a control group. By using a combined Doppler and echo-tracking system, changes in vascular diameter (dD) and blood flow velocity (dV) were recorded simultaneously at the common carotid artery and dD x dV was measured as WI. In the components of WI, the positive component of early systolic phase (FE) and the negative component following FE (B) were significantly reduced in the DCM group. There was a significant positive correlation between FE and B in all 3 groups.The appearance time of B was significantly shorter in the HCM group and significantly longer in the DCM group compared with the control group. Conclusions — It was suggested that the value of the reflection pressure wave was influenced by the left ventricular contractility, and that the effect of the reflection pressure wave appeared earlier in patients with HCM and later in patients with DCM compared with the control subjects.
