It is becoming increasingly clear that the intrinsic properties of both the heart and
vasculature exhibit dramatic oscillations over the course of the day. Diurnal variations in the …

The onset of cardiovascular diseases often shows time-of-day variation. Acute myocardial
infarction or ventricular arrhythmia such as ventricular tachycardia occurs mainly in the early …

Time plays a crucial role in the regulation of physiological processes. Without a temporal
control system, animals would be unprepared for cyclic environmental changes, negatively …

The cardiovascular diseases are closely related to circadian rhythm, which is under the
control of the biological clock. Clock genes show circadian oscillation not only in the …

The time of onset of cardiovascular disorders such as myocardial infarctions or ventricular
arrhythmias exhibits a circadian rhythm. Diurnal variations in autonomic nervous activity …

Virtually all aspects of physiology fluctuate with respect to the time of day. This is beautifully
exemplified by cardiovascular physiology, for which blood pressure and electrophysiology …

Cardiovascular functions, including blood pressure and vascular functions, show diurnal
oscillation. Circadian variations have been clearly shown in the occurrence of …

Endogenous nitric oxide (NO) is an important mediator in the processes that control
biological clocks and circadian rhythms. The present study was designed to elucidate if NO …

Cardiovascular functions such as heart rate and blood pressure show 24h variation. The
incidence of cardiovascular diseases including acute myocardial infarction and arrhythmia …

TGR (mREN2) 27 (TGR) rats develop severe hypertension and an inverted circadian blood
pressure profile with peak blood pressure in the daytime rest phase. The present study …
