OBJECTIVE: This study aimed to investigate the prevalence, characteristics, and associated clinical factors of arrhythmias-particularly atrial fibrillation (AF) and high-grade premature ventricular contractions (PVCs)-as detected by 24-hour Holter ECG monitoring in hospitalized elderly patients with diagnosed heart failure with ejection fraction ≤ 50%.
METHODS: A cross-sectional study was conducted between May 2023 to March 2024 at the Cardiovascular Institute, 108 Central Military Hospital, Hanoi, Vietnam. A total of 72 hospitalized patients aged ≥ 65 years with confirmed heart failure (LVEF < 50%) were enrolled. Clinical characteristics, laboratory data, echocardiographic parameters, and 24-hour Holter monitoring results were collected. Multivariable logistic regression with stepwise forward selection (p-entry < 0.2) was used to identify predictors of AF and high-grade PVCs (Lown grade III-V).
RESULTS: The mean age was 73.7 ± 8.9 years, and 66.7% were male. AF was detected in 19.4% of patients, while a high PVC burden was common, with a median (25th -75th ) of 1955 (54-38514) and 58.3% falling into Lown grades III-V. Multivariable analysis identified increased body mass index (OR = 1.71, 95% CI: 1.18-2.48, p = 0.005) and elevated systolic pulmonary artery pressure (sPAP) (OR = 1.06, 95% CI: 1.00-1.13, p = 0.049) as independent predictors of AF. For high-grade PVCs, significant predictors included elevated sPAP (OR = 1.06, 95% CI: 1.01-1.12, p = 0.024), lower creatinine (OR = 0.99, 95% CI: 0.98-1.00, p = 0.014).
CONCLUSION: AF and high-grade PVCs are common in hospitalized elderly patients with diagnosed heart failure and are associated with distinct clinical and laboratory parameters. Elevated sPAP was a shared predictor of both arrhythmias. These findings support the use of integrated echocardiographic and Holter monitoring for risk stratification and management in this population.
