Insights
Primary hyperaldosteronism (PHA) significantly contributes to hypertension and cardiac damage. This study found 6% of hypertensive patients had PHA, showing greater left ventricular hypertrophy and mass compared to other hypertensive groups.
Area of Science:
- Cardiology
- Endocrinology
- Hypertension Research
Context:
- Primary hyperaldosteronism (PHA) is increasingly recognized as a cause of secondary hypertension.
- Cardiovascular complications are a significant concern in hypertensive patients.
Purpose:
- To determine the prevalence of PHA in a cohort of hypertensive patients.
- To assess the cardiac damage associated with PHA compared to other forms of hypertension.
Summary:
- 183 hypertensive patients underwent a secondary hypertension work-up, including ECG and echocardiography.
- 11 patients (6%) were diagnosed with PHA.
- PHA patients exhibited higher systolic blood pressure, increased left ventricular hypertrophy on ECG (45.5% vs 11.6%), and greater left ventricular mass (145.5 g/m² vs 97.52 g/m²) compared to non-PHA hypertensives.
Impact:
- PHA is a significant, often undiagnosed, contributor to hypertension prevalence.
- PHA is associated with more severe cardiac damage, specifically left ventricular hypertrophy and increased mass, than other hypertensive causes.
- Highlights the importance of screening for PHA in hypertensive individuals to mitigate cardiovascular risk.
Abstract:
Primary hyperaldosteronism (PHA) is thought to have a harmful effect on the cardiovascular system and, in recent years, the number of cases of hypertension due to PHA has been increasing. The aims of this study were to determine the prevalence of PHA and to assess cardiac damage associated with the condition in 183 consecutive hypertensive patients. A full secondary hypertension work-up was performed, and included ECG and echocardiography. In total, 11 (6%) patients were diagnosed with PHA. Compared with other hypertensives, those with PHA had higher systolic blood pressure, more frequently had evidence of left ventricular hypertrophy on ECG (45.5% vs 11.6%; P< .01), and had a larger left ventricular mass on echocardiography (145.5 g/m(2) vs 97.52 g/m(2); P< .0001). In conclusion, PHA is a significant contributor to the increasing prevalence of hypertension and its effect on the heart is greater than that of other causes of hypertension.
