Insights
Antihypertensive therapy trials often focus on cardiovascular events, neglecting lesion prevention. New methods can assess if certain drugs, like calcium-channel blockers, better prevent or regress atherosclerotic plaques.
Area of Science:
- Cardiology
- Pharmacology
- Hypertension Research
Context:
- Major randomized trials for antihypertensive therapy primarily use cardiovascular events as endpoints.
- This focus has limited understanding of therapy's role in preventing underlying cardiovascular lesions.
- Current understanding is insufficient regarding the prevention or regression of atherosclerotic plaques by antihypertensive agents.
Purpose:
- To evaluate the effectiveness of antihypertensive therapy in preventing cardiovascular lesions.
- To determine if specific drug classes, such as calcium-channel blockers, are more effective than traditional agents in managing atherosclerotic plaques.
- To explore the potential for regression of atherosclerotic plaques using antihypertensive treatments.
Summary:
- Quantitative evaluation methods for organ damage in hypertension are now available.
- Non-invasive techniques like quantitative ultrasonography of carotid artery walls can be utilized in large trials.
- These methods allow for assessing the impact of antihypertensive drugs on atherosclerotic plaque development and regression.
Impact:
- Provides crucial data on the primary goal of therapy for mild to moderate hypertensives: prevention of cardiovascular lesions.
- Offers insights into whether specific antihypertensive drug classes offer superior benefits in managing atherosclerosis.
- Enables more targeted and effective therapeutic strategies for hypertension management and cardiovascular disease prevention.
Abstract:
All major randomized trials of antihypertensive therapy have used cardiovascular events as endpoints. This approach has provided important information, but has also led to a few inappropriate conclusions. In particular, no sound information is available on the ability of antihypertensive therapy to prevent the cardiovascular lesions upon which events are superimposed. However, particularly in mild to moderate hypertensives, the primary goal of therapy is prevention of cardiovascular lesions rather than prevention of premature death. Sensitive and quantitatively reliable methods for evaluation of organ damage in hypertension are now available. For instance, the quantitative evaluation of coronary plaques has recently been employed in therapeutic trials of coronary artery disease; non-invasive methods (such as quantitative ultrasonography of carotid artery walls) can be employed in large trials of antihypertensive therapy to answer the question whether some class of antihypertensive drugs, such as calcium-antagonists) may be more effective in prevention and/or regression of atherosclerotic plaques than traditional antihypertensive agents.
