What You Need to Know Before You Apply

What is the purpose of this trial?

To establish the effectiveness and tolerability of standard of care anti-anginal treatment (beta-blocker and calcium channel blocker medications) in older adults with symptomatic Stable Ischemic Heart Disease (SIHD) and multiple chronic conditions (MCC).

Will I have to stop taking my current medications?

If you are currently taking beta-blockers or calcium channel blockers, you cannot participate in this trial. The trial does not specify about other medications, so it's best to discuss with the trial team.

Are beta blockers and calcium channel blockers generally safe for humans?

Beta blockers like metoprolol, bisoprolol, and carvedilol are generally safe with a low risk of serious side effects if used correctly, though they can cause issues like slow heart rate or breathing problems in some cases. Calcium channel blockers are not specifically mentioned in the provided research, but beta blockers have been shown to be safe in large studies for conditions like heart failure. ^{1 2 3 4 5}

What makes the drug for stable angina unique?

The drug for stable angina is unique because it compares beta blockers, which can have additional benefits like vasodilation and antioxidant properties, with calcium channel blockers. Some beta blockers, like nebivolol, also improve blood vessel function by releasing nitric oxide, which can be beneficial for heart health. ^{6 7 8 9 10}

What evidence supports the effectiveness of beta blockers for treating stable angina?

Research shows that beta blockers like carvedilol, metoprolol, and bisoprolol improve survival and symptoms in heart failure patients, suggesting they may also help with stable angina. These drugs have additional benefits like reducing blood pressure and improving heart function, which can be beneficial for angina. ^{4 6 9 11 12}

Published Research Related to This Trial

In a study of 29 heart failure patients, replacing carvedilol with propranolol did not worsen heart function, as measured by ejection fraction, after 6 months, indicating that propranolol can be a safe alternative.

The study found that propranolol led to a significant increase in ejection fraction, suggesting it may be effective in improving heart function in patients previously stabilized on carvedilol.

Beta-adrenergic receptor blockers, such as bisoprolol, metoprolol, and carvedilol, have been proven to significantly improve survival rates and reduce hospitalization in heart failure patients, leading to better overall patient well-being.

While investigational beta-blocker bucindolol showed only mild improvements in survival, the differences in properties among beta-blockers, such as selectivity and vasodilation effects, remain to be fully understood in terms of their impact on treatment outcomes.

Third generation beta-adrenoceptor antagonists, like nebivolol and carvedilol, not only lower blood pressure but also improve vascular function through mechanisms such as nitric oxide-mediated vasodilation and anti-inflammatory effects.

These drugs have been shown to reduce mortality and morbidity in conditions like heart failure and post-myocardial infarction, highlighting their efficacy in treating cardiovascular diseases.

Long-term beta-blocker therapy has shown beneficial effects in over 13,000 patients with chronic heart failure, with metoprolol, bisoprolol, and carvedilol demonstrating positive impacts on prognosis, although they differ in their pharmacologic characteristics.

Carvedilol may offer a more comprehensive blockade of adrenergic receptors compared to selective beta-blockers like metoprolol and bisoprolol, potentially leading to better left ventricular function, but the long-term effects on patient outcomes are still being evaluated in the ongoing COMET trial with over 3,000 participants.

Only three beta-blockers—carvedilol, bisoprolol, and metoprolol succinate—have shown positive effects on prognosis in chronic heart failure patients, highlighting their importance in treatment.

Carvedilol not only blocks beta(1)-adrenergic receptors but also beta(2)- and alpha(1)-adrenergic receptors, and has additional properties that may contribute to its superior mortality reduction compared to metoprolol, as demonstrated in the COMET trial.

Modern beta blockers, including metoprolol, bisoprolol, atenolol, and carvedilol, are generally safe with a low incidence of serious side effects when used appropriately, making them suitable for a variety of medical conditions.

These medications have shown significant prognostic benefits in large clinical trials, particularly for patients recovering from heart attacks and those with heart failure.

Beta-blockers with vasodilating properties, such as nebivolol, are more effective in reducing left ventricular workload and improving arterial health compared to non-vasodilator beta-blockers like propranolol and atenolol, which do not positively affect arterial thickness or rigidity.

Third-generation beta-blockers, including celiprolol, carvedilol, and nebivolol, possess antioxidant properties that may protect endothelial function and minimize harmful metabolic effects, making them potentially safer options for long-term treatment in hypertensive patients.

Chronic heart failure (CHF) is more common in elderly patients, yet most studies on beta-adrenoceptor antagonists have excluded those over 63 years old, raising concerns about the applicability of these treatments to older populations.

Nebivolol, a third-generation beta-adrenoceptor antagonist, has shown significant efficacy in reducing the risk of death or cardiovascular hospitalization in elderly CHF patients, making it the preferred choice for this demographic.

In a comparison of beta-blockers for heart failure, bisoprolol, carvedilol, and metoprolol CR/XL showed similar efficacy in reducing mortality and hospitalization rates among patients with systolic heart failure, regardless of their NYHA class or ejection fraction.

Nebivolol was found to be less effective and not better tolerated than the other beta-blockers, indicating that it may not be the best choice for patients with heart failure.

Recent clinical trials have shown that beta-blockers like carvedilol and metoprolol succinate significantly reduce morbidity and mortality in heart failure, while other beta-blockers lack supporting evidence for their use.

Differences in the pharmacokinetic and pharmacodynamic properties of beta-blockers mean that not all beta-blockers are equally effective in heart failure, highlighting the need for further studies to compare carvedilol directly with metoprolol succinate.

Conventional beta-blockers may lead to poorer clinical outcomes and negatively affect quality of life, lipid, and carbohydrate metabolism compared to other antihypertensive medications, raising concerns about their use in treating hypertension.

Nebivolol, a cardioselective vasodilating beta-blocker, may offer advantages in treating complicated hypertension, especially in patients with diabetes, the elderly, and African Americans, highlighting the importance of considering the mechanism of action when selecting a beta-blocker.

Celiprolol is an effective treatment for angina pectoris, showing significant benefits compared to placebo in multiple studies.

Its efficacy in managing angina and ischemia is comparable to traditional beta-blockers like propranolol and atenolol, while also offering unique hemodynamic properties due to its selective adrenergic-blocking and vasodilator effects.
