Effect of antihypertensive therapy on ventricular-arterial mechanics, coupling, and efficiency
Key result
Antihypertensive therapy decreased systolic blood pressure from 154 to 137 mmHg and significantly improved ventricular-arterial coupling, cardiac work, and LV efficiency (P<0.001).

Implication
May improve ventricular-arterial coupling in early hypertension; hypothesis-generating, requires randomized confirmation before practice change.
Key Points
- The aim is to evaluate how antihypertensive therapy influences ventricular-arterial mechanics and efficiency in early-stage hypertension.
- Analyzed data from two clinical trials with 527 participants aged ≥45 with early-stage hypertension and diastolic dysfunction.
- Assessed left ventricular structure and function using Doppler echocardiography before and after 24-38 weeks of treatment.
- Measured changes in systolic blood pressure, arterial stiffness, and ventricular efficiency.
- Systolic blood pressure decreased from 154 ± 18 to 137 ± 15 mmHg post-treatment (P < 0.001).
- Significant reduction in arterial and ventricular stiffness, with enhancements in systemic arterial compliance (all P < 0.001).
- Women and obese individuals experienced less improvement in ventricular-arterial coupling compared to men and non-obese individuals (P = 0.04 and 0.007, respectively).

Lam et al. (2012) conducted a cohort in early-stage hypertension (n=527). Antihypertensive therapy vs. Baseline (pre-therapy) was evaluated on ventricular and arterial stiffness, systemic arterial compliance and resistance, LV ejection, and cardiac work (p=< 0.001). Antihypertensive therapy decreased systolic blood pressure from 154 to 137 mmHg and significantly improved ventricular-arterial coupling, cardiac work, and LV efficiency (P<0.001).
