Abstract

BACKGROUND: Left ventricular hypertrophy constitutes a powerful independent risk factor for heart failure, sudden death and ventricular dysrhythmia. Experimental data suggest that, apart from increased cardiac work load, noradrenaline may be one of the factors triggering myocardial hypertrophy. OBJECTIVE: To test the hypothesis that the extent of left ventricular hypertrophy is coupled to cardiac noradrenaline independently from the magnitude of arterial blood pressure. PATIENTS AND METHODS: Following exclusion of coronary artery disease by cardiac catheterization, cardiac noradrenaline release was measured in relation to left ventricular mass in 25 patients with arterial hypertension (HT), of whom five had left ventricular hypertrophy (HT + LVH) and 20 had normal left ventricular mass (HT - LVH), seven normotensive patients with hypertrophic cardiomyopathy (HCM) and a normotensive control group (n = 7). Noradrenaline was measured in arterial and coronary venous plasma using high-performance liquid chromatography. Coronary blood flow was quantified using the gas chromatographic argon method. Indices of left ventricular mass were calculated from the end-diastolic thicknesses of the interventricular septum and the posterior wall determined by echocardiography. RESULTS: The coronary venous plasma concentration of noradrenaline was significantly higher in HT - LVH, HT + LVH and HCM than it was in normotensives. Whereas in normotensives there was a net uptake of noradrenaline (17 +/- 10 pmol/min) across the coronary circulation, a net release of noradrenaline was observed in HT - LVH (69 +/- 26 pmol/min), in HT + LVH (121 +/- 55 pmol/min) and in HCM (341 +/- 96 pmol/min). In a multivariate linear regression analysis model, left ventricular mass correlated significantly with the net noradrenaline release rate (r = 0.64, P < 0.001), whereas arterial blood pressure as an additional independent variable did not correlate with left ventricular mass. CONCLUSION: The present data demonstrate that an increased left ventricular mass in normotensive and in hypertensive patients is closely coupled to an increased cardiac sympathetic activity, supporting the need for additional studies to determine whether adjunctive sympatholytic therapy is beneficial in patients with left ventricular hypertrophy and increased cardiac noradrenaline release.

  • In human studies, indexes of left ventricular mass have tended to correlate with plasma norepinephrine values and cardiac noradrenaline spillover.

    “Also, in human studies, indexes of LVM have tended to correlate with plasma norepinephrine values (37)and cardiac noradrenaline spillover (38).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
