The cohort comprised patients with coronary heart disease (= 823; 81.7%) and myocardial infarction (= 545; 54.1%) with a mean LVEF of 59.9% 9.3%. The mean left ventricular mass index (LVMI) was 52.1 21.2 g/m2.7 and 485 (48.2%) patients had left ventricular hypertrophy. There was no significant association of any investigated SNP (rs619824, rs743572, rs1004467, rs11191548, rs17115100) with mean 24 h systolic or diastolic BP. However, carriers of the rs11191548 C allele exhibited a 7% increase in LVMI (95% CI: 1%C12%, = 0.017) compared to non-carriers. The CYP17A1 polymorphism rs11191548 exhibited a significant association with LVMI in patients with arterial hypertension and preserved LVEF.

Left ventricular hypertrophy defined as LVMI 50 g/m2.7 in men and 47 g/m2.7 in women was observed in 485 (48.2%) patients according to de Simone [31]. The mean left ventricular ejection portion (LVEF) was 59.9% 9.3% indicating that overall left ventricular systolic function was well preserved. Left atrium was slightly dilated (41.1 5.4 mm) and internal left ventricular diastolic dimensions were in the normal range (51.1 7.0 mm).

Consequently, aldosterone is considered as one of the important humoral factors in the pathogenesis of LVH [17,47]. Clinical studies consistently indicated positive correlations between plasma aldosterone levels and remaining ventricular mass in hypertensive individuals [48,49,50,51,52]. Moreover, aldosterone receptor antagonists reduced LVMI in hypertensive individuals with remaining ventricular hypertrophy [53]. Cortisol has been described as major determinant of LVH in Cushings syndrome [19]. In untreated hypertensive individuals LVMI correlated significantly with 24 h urinary free cortisol and cortisone [18]. Finally, sex steroids, in particular androgens contribute to higher remaining ventricular mass in males compared to ladies.As a result, screening of individuals may offer the possibility for a more personalized medicine in the future including the early onset of preventive strategies. investigated SNP (rs619824, rs743572, rs1004467, rs11191548, rs17115100) with mean 24 h systolic or diastolic BP.
