Insights
Palpitations, alongside chronic heart failure, predict adverse events in hypertrophic cardiomyopathy (HCM) patients. This common genetic heart condition
Area of Science:
- Cardiology
- Genetics
- Clinical Outcomes Research
Background:
- Hypertrophic cardiomyopathy (HCM) is a prevalent genetic heart disease with varied clinical manifestations.
- Identifying novel predictors for clinical outcomes and survival is crucial for managing HCM patients.
Purpose of the Study:
- To investigate palpitation as a potential predictor of major adverse cardiovascular and cerebrovascular events (MACCE) in HCM patients.
- To assess the association between palpitation and specific adverse outcomes such as rehospitalization, cardiac death, and heart failure exacerbation.
Main Methods:
- A study involving 206 HCM patients compared outcomes related to major adverse cardiovascular and cerebrovascular events.
- Multivariable logistic analysis was employed to identify independent predictors of MACCE.
- Kaplan-Meier analysis was used to evaluate prognosis in HCM patients without atrial fibrillation.
Main Results:
- Palpitation, along with chronic heart failure (>1 year), independently predicted MACCE in HCM patients (OR 3.24, P=0.001).
- Palpitation was significantly associated with increased rehospitalization (OR 3.86, P<0.001), cardiac death (OR 2.96, P=0.04), and heart failure exacerbation (OR 4.07, P<0.001).
- Patients with palpitation did not exhibit significant differences in cardiac phenotype or function.
Conclusions:
- Palpitation emerges as a novel and independent predictor of adverse clinical outcomes and overall survival in hypertrophic cardiomyopathy patients.
- The presence of palpitation warrants close monitoring for potential adverse events, particularly in HCM patients without atrial fibrillation.
Abstract:
Hypertrophic cardiomyopathy (HCM) is a common genetic heart disease with diversified clinical presentation and it is important to identify new predictors of clinical outcomes and survival in HCM patients. In our study, 206 HCM patients were compared with respect to major adverse cardiovascular and cerebrovascular events. By multivariable logistic analysis, we determined that palpitation, together with chronic heart failure (CHF) > 1 year, was an independent predictor of major adverse cardiovascular and cerebral events (MACCE) in HCM patients (OR 3.24, 95% CI 1.60-6.57, P = 0.001). Specially, palpitation was related to higher prevalence of rehospitalization (OR 3.86, 95% CI 2.08-7.08, P < 0.001), cardiac death (OR 2.96, 95% CI 1.05-8.32, P = 0.04) and heart failure exacerbation (OR 4.07, 95% CI 2.04-8.13, P < 0.001). However, patients presented with palpitation did not show a significantly different cardiac phenotype and function. Finally, palpitation predicted a poor prognosis in HCM patients without atrial fibrillation by utilizing Kaplan-Meier analysis (P = 0.041). In conclusion, palpitation could be a new predictor of clinical outcomes and overall survival in HCM patients.
