LIVEBETTER: A Trial Comparing Medications in Older Adults With Stable Angina and Multiple Chronic Conditions

Single-blind, randomized (1:1) pragmatic trial comparing Beta-Blocker therapy versus Calcium Channel Blocker therapy in older adults with symptomatic SIHD and MCC with plans to initiate medical treatment with anti-anginal therapy.

Study Aims Aim 1: To compare the effectiveness of anti-anginal medications to improve the symptoms, function, and quality of life among older adults with multiple chronic conditions presenting with stable angina. Aim 2: To compare the tolerability and safety of commonly used anti-anginal medications in older adults with multiple chronic conditions presenting with stable angina. Aim 3 (Exploratory): To compare the long-term effectiveness and safety of specific anti-anginal medicine treatment approaches in older adults with multiple chronic conditions presenting with stable angina. LIVEBETTER consists of 4 study visits during the 12-month follow-up period. Visits are comprised of an interview, six-minute walk, and medical record review. Medication dose and administration will be addressed as part of routine clinical care.

The importance of the knowledge gained includes the following:

1. LIVEBETTER will produce randomized contemporary data on the safety and efficacy of BBs vs CCBs with the goal of filling that gap of evidence in the guidelines and informing clinical practice.

2. LIVEBETTER will generate data on the quality of life, symptomatic, and functional outcomes most pertinent to older adults with multiple chronic conditions and stable angina.

3. LIVEBETTER will provide the first quantitative data on caregiver burden in older adults with stable angina.

Cognition as measured by the Telephone Interview for Cognitive Status (TICS) is an exploratory endpoint included in the parent LIVEBETTER study. In November 2024, additional exploratory neurocognitive study measures were added as part of an ancillary neurocognitive study funded by the National Institute on Aging in September 2024. Additional measures introduced as part of this ancillary study include an extended cognitive battery and instruments to assess depression and functional status. As part of the ancillary neurocognitive study, study follow-up will be extended to 24 months. The exploratory aims of the neurocognitive ancillary study will be to compare the effect of BB vs. CCB on the rate of cognitive decline and incidence of mild cognitive impairment (MCI) and probable dementia among older adults with stable angina and MCC in the LIVEBETTER randomized clinical trial.
