ABSTRACT

Although neurohormones and Renin-Angiotensin-Aldosterone-System (RAAS) components are important predictors of cardiovascular mortality (CVM), their importance for predicting outcomes in patients with/without RAAS-blockers and different degrees of arterial stiffness is less understood. We therefore analyzed long-term data from the Ludwigshafen Risk and Cardiovascular Health (LURIC) study in 3316 patients subdivided according to pulse pressure (PP) and RAAS-blocker use. Patients on RAAS-inhibition had higher renin and noradrenaline, lower aldosterone and aldosterone/renin quotient (ARQ). Renin and noradrenaline significantly predicted CVM in patients without RAAS-blocker (HR = 1.17, 1.15) and in patients receiving angiotensin-converting-enzyme (ACE) inhibitors (HR = 1.17, 1.29), whereas aldosterone predicted CVM only in patients receiving ACE-inhibitors (HR = 1.13). CVM was predicted independently from PP by renin, noradrenaline and angiotensin II. Independently from RAAS inhibition renin decreased and ARQs increased with rising PP. Furthermore, noradrenaline increased with PP, but only without ACE-inhibition. The HR for CVM in the ACE-inhibitor group were 1.29, 1.28, 1.29 for renin in the first, second and third PP quartiles and 1.22, and 1.19 for aldosterone in the second and fourth quartile. Furthermore, we showed that noradrenaline predicts CVM in all PP quartiles in patients with ACE-inhibition. In the RAAS-blocker-free group, the HR for renin for CVM were 1.36 and 1.18 in the third and fourth PP quartiles, but neither aldosterone nor noradrenaline were predictive for CVM within the PP quartiles. Renin and noradrenaline are strong predictors of CVM regardless of RAAS blockade, whereas aldosterone is predictive only in the ACE-inhibitor group. Catecholamines but not renin are associated with rising PP.

ABSTRACT

BACKGROUND: In patients with coronary artery disease (CAD), risk stratification remains a challenge. Recently, epicardial adipose tissue (EAT) assessed by cardiovascular magnetic resonance imaging (CMRI) has emerged as a new marker in patients with CAD. Thus, we aimed to investigate the association of CMR parameters with all-cause and cardiac mortality in patients with CAD. PATIENTS AND METHODS: CMRI examination was performed in 260 patients with CAD. RESULTS: In the 40 patients who died, left ventricular (LV) ejection fraction, right ventricular fractioning shortening, LV remodeling index and indexed EAT were significantly reduced, whereas LV mass index, LV end-diastolic volume index, LV end-systolic volume index, LV end-diastolic diameter and the extent of late gadolinium enhancement expressed as a percentage of the maximum possible score to estimate the extent of LGE relative to LV mass (LGE %), were significantly elevated. Using multivariate analysis, age, LV mass index, extent of LGE % and indexed EAT proved to be independently associated with all-cause and cardiac mortality. CONCLUSION: Age, LV mass index, the extent of LGE % and indexed EAT are independent predictors of mortality that might contribute to a more accurate risk stratification of patients with CAD.
