In conclusion, patients with heart failure and reduced ejection fraction that are homozygous for ADRB1 Ser49 were significantly more likely to experience LVEF recovery than Gly49 carriers.
For example, GWAS of NT-proBNP levels not only identified variants in the NNPA-NPPB locus but also substantiated data suggesting that natriuretic peptides in itself are associated with a lower risk of hypertension and HF.
However, there were variations in associated aetiological factors between ethnic groups, with diabetes mellitus affecting the majority of Indians-as well as underutilisation of standard drugs for CHF, such as the angiotensin converting enzyme (ACE) inhibitors, which were only used in 43.3%.
The purpose of this study was to examine the association between polymorphisms of ACE and eNOS gene complexes and AF in an unselected series of patients with congestive heart failure (CHF).
Other cardiovascular complications seen in GBS patients were Increased pro-BNP(26.04%), raised troponin T levels(3.12%), acute coronary syndrome(2.08%), heart failure(2.08%) and abnormal 2D echo findings(8.33%).
The risk of sudden death has changed over time among patients with symptomatic heart failure and reduced ejection fraction with the sequential introduction of medications including angiotensin-converting-enzyme inhibitors, angiotensin-receptor blockers, beta-blockers, and mineralocorticoid-receptor antagonists.
Transplantation of either HIF-1α-modified CSCs or single CSCs reduced cardiomyocyte apoptosis in rats with heart failure after MI, promoted vascular regeneration in infarct area, and improved cardiac function.
An association between the DD allele of the angiotensin-converting enzyme gene and a poorer outcome in patients with heart failure has been found in whites.
This study suggested that angiotensinogen gene variants M235T and T174M may provide prognostic information for long-term survival in heart failure patients.
Here, 4-month adult mice, on angiotensin II (Ang II) infusion, show rapid decline in cardiac systolic function, which leads to heart failure and death in 2 weeks.
We evaluated nuclear factor kappa B {NFkB, rs28362491 [-94ins/delATTG (W/D)]} and angiotensin converting enzyme {ACE; rs1799752 [Ins(I)/Del(D)]} gene polymorphisms and their correlation with thyroid function in patients with heart failure (HF).
The deleterious effects of discontinuation of digoxin on outcomes in ambulatory patients with chronic heart failure (HF) with reduced ejection fraction (HFrEF) receiving angiotensin-converting enzyme inhibitors are well-documented.
Angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blockers (ARB) were administered in 68.9% of HF discharged patients, beta-blockers in 84.8%, mineralocorticoid receptor antagonist (MRA) in 57.9%, diuretics in 85.9%, and digoxin in 23%.
Accordingly, using mice with cardiac-specific overexpression of the angiotensin II (ANGII) type 1 receptor (AT1R), we explored male-female differences in the manifestations of hypertrophy and HF.
However, in multivariable regression analysis Cystatin C predicted mortality after the adjustment for baseline renal function, AKI, BNP levels and heart failure risk factors.
Overall, there was a significant association between angiotensinogen (AGT) gene M235T polymorphism and risk of heart failure in the subgroup analysis under the allelic contrast (T vs M: OR = 1.48, 95% CI: 1.04-2.11) and the dominant model (TT+MT vs MM: OR=1.67, 95% CI: 1.13-2.46) in the Caucasian population.
Inhibition of RAAS using angiotensin converting enzyme inhibitors (ACEi) or angiotensin receptor blockers (ARBs) have shown to significantly reduce morbidity and mortality due to HF.
The ACE genotype was determined in 171 patients selected with IDC in New York Heart Association functional class II to III heart failure and with a LV ejection fraction of < or = 40%.
We evaluated 485 patients with chronic HF to see whether the angiotensin receptor type 1 (AT1R) 1166A/C or angiotensin-converting enzyme insertion/deletion (ACE I/D) polymorphisms were associated with a higher rate of ventricular arrhythmias requiring implantable cardioverter defibrillator (ICD) therapies over a 5-year period.
We examined 535 CHF patients (mean 66 years, women 25%) in the control arm of our SUPPORT trial, in which we examined additive impact of olmesartan in hypertensive patients with symptomatic CHF treated with β-blockers and/or angiotensin-converting enzyme inhibitors.
