BMC Cardiovasc Disord 2024; 24:312. [PMID: 38902636 PMCID: PMC11188237 DOI: 10.1186/s12872-024-03925-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Accepted: 05/06/2024] [Indexed: 06/22/2024] Open
Abstract
BACKGROUND Previous studies have shown the importance of energy deficiency and malfunctioning mitochondria in the pathophysiology of hypertrophic cardiomyopathy (HCM). There has been a little research into the relationship between plasma free fatty acids (FFA), one of the heart's main energy sources, and HCM. We evaluated its clinical importance in HCM to see if there was a link between plasma FFA metabolism and HCM. METHODS In a single-center retrospective observational study, we investigated 420 HCM patients diagnosed at Beijing Anzhen Hospital between January 1, 2018, and December 31, 2022. Meanwhile, 1372 individuals without HCM (non-HCM) were recruited. 391 non-HCM patients were chosen as controls via a propensity score matching (PSM) study with a 1:1 ratio. RESULTS FFA in HCM patients showed statistically significant correlations with creatinine (r = 0.115, p = 0.023), estimated GFR (r=-0.130, p = 0.010), BNP (r = 0.152, p = 0.007), LVEF (r=-0.227, p < 0.001), LVFS (r=-0.160, p = 0.002), and LAD (r = 0.112, p = 0.028). Higher FFA levels were found in HCM patients who had atrial fibrillation and NYHY functional classes III or IV (p = 0.015 and p = 0.022, respectively). In HCM patients, multiple linear regression analysis revealed that BNP and LVEF had independent relationships with increasing FFA (Standardized = 0.139, p = 0.013 and =-0.196, p < 0.001, respectively). CONCLUSIONS Among HCM patients, the plasma FFA concentration was lower, and those with AF and NYHY functional class III or IV had higher FFA levels, and LVEF and BNP were independently associated with increasing FFA. The findings of the study should help inspire future efforts to better understand how energy deficiency contributes to hypertrophic cardiomyopathy (HCM) development.

Sex-Related Differences in the Impact of Systemic Hypertension on Left Ventricular Remodeling in Patients with Hypertrophic Obstructive Cardiomyopathy. Cardiology 2020; 145:203-214. [PMID: 32069453 DOI: 10.1159/000505680] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2019] [Accepted: 12/30/2019] [Indexed: 12/28/2022]
Abstract
BACKGROUND The clinical condition of hypertrophic obstructive cardiomyopathy (HOCM) and concomitant systemic hypertension is growing more and more prevalent, and it brings about a challenging diagnostic and therapeutic dilemma. However, whether systemic hypertension has an impact on HOCM, and whether sex-related differences exist in this impact, remains unclear. METHODS A total of 453 HOCM patients (age 48.7 ± 12.8 years, 252 [55.6%] males) were recruited in this study. There were 150 patients (33.1%, 81 males and 69 females) with a history of controlled systemic hypertension. Cardiac magnetic resonance (CMR) imaging was performed in all patients. Left ventricular (LV) remodeling index (LVRI) was determined by CMR. LVRI >1.3 g/mL was defined as pathological LV remodeling. RESULTS Men had significantly greater LVRI (1.40 ± 0.54 vs. 1.15 ± 0.38 g/mL, p < 0.001) and LVRI >1.3 g/mL (p = 0.002), compared with women. The incidence of syncope and 5-year sudden cardiac death risk score were significantly lower in HOCM with hypertension than those without hypertension. LVRI (p = 0.003) and LVRI >1.3 g/mL (p = 0.007) were significantly smaller in males with hypertension, but not in females with hypertension. However, log cardiac troponin I and log N-terminal pro-B-type natriuretic peptide were positively correlated with LVRI in men and women. On multivariable logistic analysis, hypertension (OR 0.172, 95% CI 0.056-0.528, p = 0.002) remained an independent determinant of pathological LV remodeling in males, whereas not in females. CONCLUSIONS There were significant sex differences in the impact of systemic hypertension on LV remodeling in patients with HOCM. Controlled systemic hypertension may contribute to improving LV remodeling in male patients with HOCM, but not in females.
