HerzKreislaufRisikofaktoren

HerzKreislaufR... is not a standard term in physiology; it appears to be an incomplete or stylized reference to the regulation of the cardiovascular system. In this sense, it can be understood as addressing the coordinated control of heart function and blood flow to sustain tissue perfusion. The study of cardiovascular regulation encompasses neural, hormonal, and local mechanisms that sense metabolic demands and adjust heart rate, contractility, vascular tone, and blood pressure.

Key control mechanisms include the autonomic nervous system, with sympathetic activation increasing heart rate and contractility and vasoconstriction, and parasympathetic activity reducing heart rate. Baroreceptors in the carotid sinus and aortic arch sense blood pressure and trigger reflex adjustments; chemoreceptors respond to chemical changes such as oxygen and carbon dioxide levels. Central command from higher brain centers modulates cardiovascular responses during movement and stress. Endocrine factors such as the renin-angiotensin-aldosterone system, vasopressin, and natriuretic peptides contribute to short-term and long-term regulation of vascular tone and fluid balance.

Physiologically, regulation integrates heart rate, stroke volume, preload, afterload, and peripheral resistance to maintain mean arterial pressure and tissue perfusion across activities. Clinically, impaired regulation is involved in hypertension, orthostatic intolerance, heart failure, and arrhythmias. Methods to study this field include heart rate variability analysis, blood pressure monitoring, and modelling of reflex control.

If the term is used in specific contexts, prefer the standard terms cardiovascular regulation or kardiovaskuläre Regulation.
