A 61-year-old man asks whether he can continue TRT with a bifascicular right bundle branch block, and Dr. O’Connor explains that a stable conduction abnormality does not automatically exclude testosterone therapy.

01:30

Dr. O’Connor emphasizes obtaining a transthoracic echocardiogram to evaluate cardiac structure, valves, ejection fraction, and other abnormalities in men on testosterone with cardiovascular concerns.

03:10

The discussion expands to A1C, blood pressure, cardiac function, diastolic dysfunction, heart failure with preserved ejection fraction, and early kidney disease as part of the broader evaluation.

04:30

Dr. O’Connor recommends coronary calcium imaging and advanced lipid assessment with ApoB and Lp(a), then explains that a cardiologist-confirmed stable heart condition should not automatically prohibit TRT.

Video Summary

A 61-year-old man asks whether TRT is safe with a stable right bundle branch block. Dr. O’Connor explains that the conduction abnormality itself does not automatically rule out testosterone therapy, particularly when it has been stable and appropriately evaluated by cardiology.

He emphasizes determining whether underlying cardiovascular disease is present through blood pressure, A1C, coronary calcium scoring, stress testing when appropriate, electrocardiography, and a transthoracic echocardiogram. The evaluation should also consider cardiac structure, valves, ejection fraction, diastolic function, kidney disease, and proteinuria.

Dr. O’Connor also recommends assessing coronary risk with ApoB, Lp(a), and imaging rather than relying only on LDL cholesterol. If cardiology considers the heart condition stable, he does not view the bundle branch block alone as a reason to automatically exclude TRT.

Drug Callouts

Testosterone

Testosterone is the therapy being questioned because the member has a cardiac conduction abnormality. Dr. O’Connor does not consider a stable right bundle branch block an automatic contraindication to TRT but emphasizes evaluating coronary disease, blood pressure, cardiac structure and function, kidney health, and the broader cardiovascular risk profile.

Condition Callouts

Right Bundle Branch Block

A right bundle branch block is the primary conduction abnormality discussed in this 61-year-old man considering TRT. Dr. O’Connor explains that a stable finding does not automatically prevent testosterone treatment but should be interpreted with cardiology evaluation and the patient’s complete cardiovascular status.

Coronary Artery Disease

Dr. O’Connor considers underlying coronary artery disease more important to the TRT decision than the bundle branch block alone. He recommends assessing men on testosterone with cardiovascular concerns using risk factors, coronary calcium imaging, ApoB, Lp(a), and additional testing when clinically appropriate.

Diastolic Dysfunction

Diastolic dysfunction is discussed as an early abnormality that can be identified on echocardiography before more advanced heart failure develops. Dr. O’Connor includes cardiac relaxation and structure among the issues worth evaluating in older men using testosterone.

Chronic Kidney Disease

Early kidney disease and proteinuria are discussed as cardiovascular risk factors that may coexist with heart abnormalities in men on testosterone. Dr. O’Connor includes kidney assessment within the broader preventive evaluation rather than considering TRT in isolation.

Key Takeaways

A stable right bundle branch block does not automatically mean a man cannot use testosterone therapy.
Cardiology evaluation should determine whether underlying coronary disease or structural heart disease is present before making TRT decisions.
A transthoracic echocardiogram can evaluate cardiac structure, valves, ejection fraction, and diastolic function.
Blood pressure and A1C remain important cardiovascular risk markers when evaluating an older man on testosterone.
Coronary calcium imaging, ApoB, and Lp(a) can provide cardiovascular information beyond a standard LDL cholesterol measurement.
If the conduction abnormality is stable and the cardiovascular evaluation is reassuring, Dr. O’Connor does not consider it an automatic reason to withhold TRT.
