Insights
Atrioventricular plane displacement is a strong predictor of mortality in heart failure patients. Higher displacement values correlate with increased risk, highlighting its prognostic value.
Area of Science:
- Cardiology
- Clinical Medicine
- Diagnostic Imaging
Background:
- Heart failure (HF) is a complex clinical syndrome with significant morbidity and mortality.
- Accurate prognostic markers are crucial for managing heart failure patients.
- Atrioventricular plane displacement (AVPD) is a measure of cardiac function that may hold prognostic significance.
Purpose of the Study:
- To evaluate the prognostic capability of atrioventricular plane displacement in predicting mortality among patients diagnosed with heart failure.
- To establish a relationship between varying degrees of AVPD and one-year mortality rates.
Main Methods:
- Prospective observational study involving 181 heart failure patients.
- Measurement of atrioventricular plane displacement at baseline.
- One-year follow-up for mortality assessment, stratified by AVPD categories.
Main Results:
- Overall mortality was 22.7% (41/181) over one year.
- A highly significant association (P = 0.001) was found between AVPD and mortality.
- Mortality rates increased progressively with decreasing AVPD: 0% for >= 10.0 mm, 10.3% for 8.2-9.9 mm, 19.4% for 6.4-8.1 mm, and 36.6% for < 6.4 mm.
Conclusions:
- Atrioventricular plane displacement is a potent and independent predictor of mortality in heart failure.
- This echocardiographic parameter can effectively stratify risk in heart failure populations.
- AVPD measurement offers valuable prognostic information for clinical decision-making in heart failure management.
Objective:
To assess the prognostic value of atrioventricular plane displacement in heart failure patients.
Design:
Patients were followed prospectively for one year after atrioventricular plane displacement determination.
Setting:
Malmö University Hospital, with a primary catchment area of 250,000 inhabitants.
Patients:
181 patients with a clinical diagnosis of heart failure; age 75.7 (SD 5.2) years, duration of heart failure 2.7 (5.7) years; 100 men, 81 women.
Main Outcome Measures:
Mortality in relation to atrioventricular plane displacement.
Results:
Total mortality was 22.7% (41/181), and was highly significantly (P = 0.001) related to atrioventricular plane displacement. Mortality within prospectively defined categories of displacement was: > or = 10.0 mm, 0% (0/19); 8.2 to 9.9 mm, 10.3% (3/29); 6.4 to 8.1 mm, 19.4% (12/62); and < 6.4 mm, 36.6% (26/71). The groups were similar in age, sex, angiotensin converting enzyme inhibitor and beta blocker treatment, and cause and duration of heart failure.
Conclusions:
Mortality in heart failure is strongly related to atrioventricular plane displacement.
