Insights
Perindopril significantly reduced P wave dispersion (PWD) in hypertensive patients, indicating improved atrial electrical activity. This suggests ACE inhibitors may help prevent atrial fibrillation by targeting key electrocardiographic markers.
Area of Science:
- Cardiology
- Pharmacology
Background:
- Angiotensin-converting enzyme inhibitors (ACEIs) are known to prevent atrial fibrillation (AF) by managing blood pressure and improving atrial remodeling.
- Increased P wave dispersion (PWD) serves as a non-invasive electrocardiographic marker for paroxysmal atrial fibrillation.
Purpose of the Study:
- To evaluate the impact of perindopril, an ACEI, on P wave dispersion (PWD) in patients with hypertension.
Main Methods:
- Forty-eight hypertensive patients were enrolled.
- Blood pressure and 12-lead electrocardiograms were recorded at baseline and at multiple time points up to six months during perindopril treatment.
- P wave dispersion was calculated as the difference between maximum and minimum P wave durations.
Main Results:
- Perindopril treatment significantly shortened PWD at one, three, and six months compared to baseline and one-week measurements (p<0.001).
- Baseline PWD correlated with body mass index, and six-month PWD correlated with left atrial volume index.
- Multiple linear regression indicated that six-month PWD was related to baseline PWD.
Conclusions:
- Perindopril treatment demonstrated a significant reduction in P wave dispersion among hypertensive patients.
- These findings suggest perindopril's potential role in mitigating atrial electrical abnormalities associated with hypertension.
Introduction:
Angiotensin-converting enzyme inhibitors prevent atrial fibrillation episodes by effective control of blood pressure and improving electrical and structural remodelling in the atria. Increased P wave dispersion (PWD) is a non-invasive electrocardiographic marker for paroxysmal atrial fibrillation. The aim of the study was to evaluate the effect of perindopril treatment on PWD in hypertensive patients.
Methods:
Forty-eight hypertensive patients (mean age 57.4+/-11.8 years, 18 men) were included. Blood pressure values were determined and 12-lead electrocardiograms were recorded at the beginning and at the first week, first month, third month and sixth month of the perindopril treatment.The difference between maximum and minimum P wave durations was calculated as PWD.
Results:
PWDs were significantly shortened at the first, third and sixth months (41.7+/-8.8 ms, 39.1+/-6.9 ms and 38.3+/-7.1 ms, respectively) compared with baseline and first-week measurements (54.3+/-9.2 ms and 49.0+/-9.1 ms, respectively, p<0.001). Baseline PWD was correlated with body mass index (r=0.32, p=0.026), while PWD at the sixth month of treatment was significantly correlated with left atrial volume index (r=0.30, p=0.042). Multiple linear regression analysis revealed that PWD at the sixth month was related to baseline PWD (p=0.001).
Conclusion:
Perindopril treatment significantly reduced PWD in hypertensive patients.
