Isolated calcium-tolerant rat ventricular cardiomyocytes were used to characterize the effects of atrial natriuretic peptide (ANP), Angiotensin II (AII) and their interaction on the myocardial contraction-/relaxation pattern free of interference from other types of cardiac cells. Binding of 125I-ANP showed a KD of 12 pM and approximately 600 binding sites per cell. At 37 degrees C (rate 140 bpm) ANP decreased the contraction maximum with an EC50 of about 70 pM, maximal decrease was 35%. ANP (10(-7) M) raised cellular cyclic-GMP from 0.76+/-0.12 to 1.32+/-0.13 pmole/10(6) cells (73%, p less than 0.05). Angiotensin II increased contractility by a maximum of 32% at 10(-7) M; the EC50 was 8 x 10(-10) M. AII markedly delayed relaxation (reduction of maximum relaxation velocity from 0.092 to 0.063 mm/s; p less than 0.05). ANP (10(-7) M) increased the effect of AII (10(-8) M) on contractility by 66% without changing relaxation parameters significantly. This unexpected interaction may be relevant in pathological conditions where both AII and ANP are stimulated, such as heart failure or secondary hypertension. [less ▲]

Relaxation delay is an important feature of hypertensive heart disease which impairs diastolic coronary flow and ventricular filling and therefore contributes to heart failure. We investigated the hypothesis that impaired relaxation is a property of the myocardium, rather than the consequence of ischaemia or interstitial fibrosis. A new videomicroscope system was used to define the contraction-relaxation cycle of isolated cardiac myocytes from spontaneously hypertensive rats (SHR) and normotensive control (Wistar-Kyoto, WKY) rats. The SHR cells showed a marked relaxation delay. Angiotensin II (Ang II) increased the contraction maximum by about 35% in WKY rats and induced a relaxation delay. In SHR Ang II greatly potentiated this relaxation delay. Our results demonstrate that impairment of relaxation is a property of the single cardiomyocyte. Angiotensin II induces a relaxation delay that is independent of blood pressure. The combination of hypertrophy and high levels of Ang II potentiates relaxation impairment and may therefore contribute to hypertensive left ventricular failure. [less ▲]

The role of atrial natriuretic peptide (ANP) in the pathogenesis of essential hypertension has not yet entirely been clarified. We investigated whether the increase of ANP in essential hypertension may be explained by elevated right atrial pressures and/or a different relationship between right atrial pressures and ANP secretion. Patients with stable essential hypertension undergoing right and left heart catheterization because of suspected coronary heart disease had significantly higher ANP levels than normotensives: 58.7 +/- 6.7 pg/ml in hypertensives versus 42.0 +/- 4.1 pg/ml in normotensives (p less than 0.01). Matching hypertensives with normotensives at identical levels of left ventricular enddiastolic pressure revealed significantly higher mean pulmonary artery pressures in hypertensives. Right atrial diastolic pressure (v-wave) after matching for LVEDP was 4.8 +/- 0.5 mm Hg in hypertensives and 3.1 +/- 0.2 mm Hg in normotensives (p less than 0.05). In addition, at any given mean right atrial pressure hypertensives showed higher ANP levels than normotensives. These results demonstrate that hypertensives exhibit raised pressures in the pulmonary artery independent of left ventricular pressure load. The elevation in right atrial pressures and the steeper relationship between these pressures and ANP are a suitable explanation for raised ANP levels in hypertension. ANP in essential hypertension may represent a counterregulation against elevated pulmonary resistance. [less ▲]
