Abstract

Limited data are available regarding the effect of metabolic syndrome on heart failure (HF) development in young individuals. Utilizing data from the Korean National Health Insurance Service, we included a total of 1,958,284 subjects in their 40s who underwent health screening between January 2009 and December 2009 in Korea. Subjects were classified into three groups: normal, pre-metabolic syndrome (Pre-MetS), and metabolic syndrome (MetS). MetS was identified in 10.58% of males and 5.21% of females. The hazard ratio for HF in subjects with MetS was 1.968 (95% CI: 1.526–2.539) for males and 2.398 (95% CI: 1.466–3.923) for females. For those with Pre-MetS, the hazard ratio was 1.607 (95% CI: 1.293–1.997) in males and 1.893 (95% CI: 1.43–2.505) in females. Additionally, acute myocardial infarction and low hemoglobin levels were identified as significant risk factors for HF in both genders. MetS approximately doubled the risk of developing HF in individuals in their 40s. Pre-MetS was also a significant risk factor for HF in this population. [ABSTRACT FROM AUTHOR]

Abstract

Abstract Background Risk stratification of the early repolarization pattern (ERP) is needed to identify malignant early repolarization. J-point elevation with a horizontal ST segment was recently suggested as a malignant feature of the ERP. In this study, the prevalence of the ERP with a horizontal ST segment was examined among survivors of sudden cardiac arrest (SCA) without structural heart disease to evaluate the value of ST-segment morphology in risk stratification of the ERP. Methods We reviewed the data of 83 survivors of SCA who were admitted from August 2005 to August 2010. Among them, 25 subjects without structural heart disease were included. The control group comprised 60 healthy subjects who visited our health promotion center; all control subjects were matched for age, sex, and underlying disease (diabetes mellitus, hypertension). Early repolarization was defined as an elevation of the J point of at least 0.1 mV above the baseline in at least two continuous inferior or lateral leads that manifested as QRS slurring or notching. An ST-segment pattern of Results The SCA group included 17 men (64%) with a mean age of 49.7 ± 14.5 years. The corrected QTc was not significantly different between the SCA and control groups (432.7 ± 37.96 vs. 420.4 ± 26.3, respectively; p = 0.089). The prevalence of ERP was not statistically different between the SCA and control groups (5/25, 20% vs. 4/60, 6.7%, respectively; p = 0.116). The prevalence of early repolarization with a horizontal ST segment was more frequent in the SCA than in the control group (20% vs. 3.3%, respectively; p = 0.021). Four SCA subjects (16%) and one control subject (1.7%) had a J-point elevation of >2 mm (p = 0.025). Four SCA subjects (16%) and one (1.7%) control subject had an ERP in the inferior lead (p = 0.025). Conclusion The prevalence of ERP with a horizontal ST segment was higher in patients with aborted SCA than in matched controls. This result suggests that ST morphology has value in the recognition of malignant early repolarization.

Abstract

Background: Although a better survival rate in women than in men has been reported in heart failure (HF) with reduced ejection fraction (HFrEF), the sex-specific prognosis has scarcely been addressed in HF with preserved EF (HFpEF). Thus, this study investigated the sex difference in clinical outcomes in patients with HFpEF, as well as in those with HFrEF. Materials and Methods: We studied clinical outcomes of 2,572 hospitalized patients due to HF (66.8 ± 14.4 years, 49.7% women) in the Korean Heart Failure Registry. Patients were divided into two groups by left ventricular EF (LVEF): HFpEF (LVEF ≥50%, n = 764) and HFrEF (LVEF <40%, n = 1,808) groups. Results: During a median follow-up of 1,121 days, there were 693 (28.7%) deaths and 1,073 (44.5%) composite events (death and HF readmission). There were no sex differences in the incidence of death or composite events during follow-up in both HFrEF and HFpEF groups (p > 0.05 for each). In 1:1 age-matched population (n = 1,005 in each sex), the long-term mortality was significantly lower in women than men in HFrEF group (p = 0.005), but not in HFpEF group (p = 0.786), while the incidences of composite events were similar between sex irrespective of LVEF (p > 0.05). However, there were no significant associations between sex and clinical outcomes in multivariable analysis (p > 0.05 for each). Conclusions: Sex per se was not the significant factor determining long-term clinical outcomes in HF patients regardless of the LVEF. [ABSTRACT FROM AUTHOR]
