Cardiovascular Disease

For decades, rest was prescribed after a cardiac event. The evidence has entirely reversed that position. Structured, supervised exercise is now one of the most powerful interventions available for cardiovascular health.

What Is Cardiovascular Disease?

Cardiovascular disease (CVD) is an umbrella term covering a range of conditions affecting the heart and blood vessels. The most common presentations include coronary artery disease (CAD) — narrowing or blockage of the arteries supplying the heart — which can lead to angina, myocardial infarction (heart attack), and heart failure. Other common conditions include hypertension (chronically elevated blood pressure), post-bypass or post-valve surgery recovery, peripheral arterial disease, and arrhythmias.

Cardiovascular disease remains the leading cause of death in Australia and globally, despite substantial advances in pharmacological and surgical management. What is increasingly understood is that the long-term trajectory of CVD — quality of life, functional capacity, rate of disease progression, and survival — is profoundly influenced by lifestyle factors, and exercise is the most powerful of them.

The shift away from post-cardiac rest and toward active, supervised rehabilitation was one of the most significant evidence-based changes in cardiovascular medicine of the past three decades. Exercise physiologists are specifically trained and credentialled to prescribe exercise safely and effectively in this population — accounting for the clinical complexity, medication interactions, and monitoring requirements that cardiovascular conditions demand.

How Exercise Physiology Helps

The mechanisms by which exercise benefits cardiovascular health are extensive and well-established. Regular aerobic training improves cardiac output, reduces resting heart rate, lowers blood pressure, improves endothelial function, reduces arterial stiffness, and favourably alters lipid profiles. Over time, these adaptations reduce the load on the heart and reduce the inflammatory and atherosclerotic processes that drive CVD progression.

Resistance training, once viewed with caution in cardiac populations, is now supported by strong evidence. It improves muscular strength and endurance, reduces the cardiovascular demand of daily activities, and contributes to better body composition and metabolic health. Current guidelines recommend both aerobic and resistance training for most cardiac patients, with intensity and volume calibrated to individual capacity and risk.

For post-event and post-surgical clients, structured cardiac rehabilitation — of which exercise is the central component — is associated with substantial reductions in mortality and readmission. The evidence base here is among the strongest in all of clinical medicine: exercise rehabilitation works, and the people who participate in it live longer and function better.

What to Expect

Medical clearance and liaison with your cardiologist or GP is the first step — understanding your diagnosis, current medications, recent investigations (ECG, echocardiogram, stress test), and any restrictions or precautions. From there, exercise intensity is prescribed using appropriate targets: heart rate zones, rating of perceived exertion (RPE), and where relevant, metabolic equivalents (METs) from stress testing.

The program begins conservatively and progresses as tolerance and fitness improve. Blood pressure monitoring before and after exercise, symptom monitoring during sessions, and clear education on warning signs that require stopping are standard components of every program. Sessions can be delivered face-to-face in Brisbane or via online remote delivery, depending on clinical suitability and preference.

• Medical clearance and liaison with your cardiologist or GP
• Safe intensity prescription — appropriate heart rate and exertion targets
• Progressive aerobic conditioning (walking, cycling, light resistance)
• Education on exertion warning signs and when to stop
• Blood pressure monitoring and tracking exercise response over time
