Top panel from Opie LH: From Cell to Circulation. The Human Cardiovascular System. New York, Raven Yeetmezlii,p The formula shown is derived from the Laplace law. The increased left ventricular LV pressure in aortic stenosis is compensated for by LV wall hypertrophy, which decreases the denominator on the right side of the equation.

When the overload is predominantly due to an increase in pressure e. When the overload is predominantly due to an increase in ventricular volume, the increase in diastolic wall stress leads to the series addition of sarcomeres, lengthening of cardiac myocytes, and LV dilation, which is referred to as eccentric chamber hypertrophy.

From Colucci Dekompanae [ed]: Cardiac Function and Dysfunction.

Philadelphia, Current Medicine,p 4. The net effect of these neurohumoral responses is to produce arterial vasoconstriction to help maintain arterial pressurevenous constriction to increase venous pressureand increased blood volume.

In general, dekompansee neurohumoral responses can be viewed as compensatory mechanisms, but they can also aggravate heart failure by increasing ventricular afterload depresses stroke volume and increasing preload to the point where pulmonary or systemic congestion and edema occur.

Parasympathetic control of heart rate is also under potent arterial baroreflex control. Efferent sympathetic traffic and arterial catecholamines are low, and heart rate variability is high.

The net response to this altered balance includes a generalized increase in sympathetic nerve traffic, blunted parasympathetic and sympathetic control of heart rate, and impairment of the reflex sympathetic regulation of vascular resistance. Anterior wall ischemia has additional excitatory effects on efferent sympathetic nerve traffic.

See text for deoompanse. Alterations in the sympathetic and parasympathetic nervous system in HF. In Mann DL [ed]: Philadelphia, Elsevier,pp. The sympathetic nervous system appears to be the primary integrator of the neurohumoral vasoconstrictor response to arterial underfilling.

Activation of renal sympathetic nerves stimulates the release of arginine vasopressin AVP. Sympathetic activation also causes peripheral and renal vasoconstriction, as does angiotensin II.

Angiotensin II constricts blood vessels and stimulates the release of aldosterone from the adrenal gland, and it also increases tubular sodium reabsorption and yrtmezlii remodeling of cardiac myocytes. Aldosterone may also have direct cardiac effects, in addition to increasing the reabsorption of sodium and the secretion of potassium and hydrogen ions in the collecting duct.

This information also assists in planning treatment and is of prognostic importance. Coronary angiography is recommended in patients with angina pectoris, who are considered suitable for coronary revascularization, to evaluate the coronary anatomy.

Left and right heart catheterization is recommended in patients being evaluated for heart transplantation or mechanical circulatory support, to evaluate right and left heart function and pulmonary arterial resistance. Exercise testing should be considered: Hepatik ve intestinal kongesyon ve bazen digital intoksikasyonu.

Assessment of clinical symptoms and signs allows for classification of patient into a hemodynamic profile and may assist in selecting initial therapy and providing prognostic information. Although this classification scheme was developed for patients with predominantly systolic dysfunction and advanced heart failure, it provides a useful construct for the evaluation of patients with AHF as well.
