Understanding Cardiovascular Health and Disease
The heart, a muscular organ, pumps blood throughout the body and:
- Delivers oxygenated blood from the lungs to the body (via the left side of the heart).
- Pumps deoxygenated blood from the body to the lungs for oxygenation (via the right side).
- Maintains blood pressure and ensures continuous circulation.
Blood Vessels
The blood vessels form a network that carries blood throughout the body:
- Arteries: Carry oxygen-rich blood away from the heart.
- Veins: Return oxygen-poor blood to the heart.
- Capillaries: Enable the exchange of oxygen, carbon dioxide, nutrients, and waste.
Blood
Blood performs vital functions, including:
- Transport: Carries oxygen, nutrients, hormones, and waste.
- Regulation: Maintains body temperature, pH balance, and fluid levels.
- Protection: Provides immune defense and clotting ability.
Together, these components sustain life, deliver essential substances, and remove waste.
Understanding Cardiovascular Disease
Cardiovascular disease (CVD) refers to conditions that affect the heart and blood vessels. It is the leading cause of death globally, but understanding its causes and prevention can significantly reduce risk.
Coronary Artery Disease (CAD)
CAD occurs when arteries supplying blood to the heart narrow or become blocked due to plaque buildup (atherosclerosis). This can result in:
- Chest pain (angina): Reduced blood flow to the heart.
- Heart attack: Complete blockage of blood flow to the heart muscle.
- Heart failure: Long-term damage from an inadequate blood supply.
For more, visit the Heart and Stroke Foundation of Canada or the American Heart Association (AHA).
Stroke
A stroke happens when the brain’s blood supply is interrupted:
- Ischemic stroke: Blockage in a blood vessel.
- Hemorrhagic stroke: Rupture of a blood vessel, causing bleeding.
Strokes can cause brain damage, disability, or death. Early intervention is critical—learn the signs of stroke from the Canadian Stroke Best Practices or the European Stroke Organisation (ESO).
Heart Failure
Heart failure occurs when the heart cannot effectively pump blood to meet the body’s needs. Symptoms include:
- Shortness of breath during mild activity.
- Fatigue and weakness.
- Swelling in legs, ankles, or feet.
For guidance, visit the Canadian Cardiovascular Society (CCS) or the American College of Cardiology (ACC).
Risk Factors for Cardiovascular Disease
Understanding risk factors empowers you to take control of your heart health.
Non-Modifiable vs. Modifiable Factors
- Non-Modifiable: Age, sex, and genetics.
- Modifiable: Lifestyle choices, such as controlling blood pressure, managing diabetes and cholesterol, quitting smoking, and staying active.
For more, visit the Heart and Stroke Foundation of Canada or the American Heart Association (AHA).
Specific Risk Factors
High Blood Pressure (Hypertension)
Hypertension is a major risk factor for heart disease and stroke. Nearly half of American adults have high blood pressure, according to the AHA.
What You Can Do: Monitor blood pressure, reduce sodium, and follow your doctor’s advice.
Learn more from the CDC.
DIABETES
Diabetes increases heart disease risk 2-4 times. High blood sugar damages blood vessels and heart-controlling nerves.
What You Can Do: Maintain healthy blood sugar levels with diet, exercise, and medication.
Visit the Canadian Diabetes Association.
HIGH CHOLESTEROL
Elevated LDL cholesterol leads to arterial plaque buildup. Adults 20+ should check cholesterol every 4-6 years, per the CDC.
What You Can Do: Eat healthier, exercise, and take medications if needed.
See the American College of Cardiology.
SMOKING
Smoking damages blood vessels, increases clot risk, and reduces oxygen in blood. Smokers are 2-4 times more likely to develop heart disease, per the WHO.
What You Can Do: Quit smoking.
Many resources, such as SmokeFree.gov, can help.

Advanced Treatment Options and Research Innovations
Exciting advancements are transforming cardiovascular care.
Recent Cardiovascular Research
PCSK9 Inhibitors
These medications lower LDL (“bad”) cholesterol by enhancing the liver’s ability to remove it.
Clinical Evidence: Reduced cardiovascular events by 15-20%, per the New England Journal of Medicine. PCSK9 inhibitors are particularly effective for individuals who do not respond well to traditional statin therapy or have genetic conditions like familial hypercholesterolemia.
For more information, visit trusted sources like AHA.
SGLT-2 Inhibitors
Initially developed for diabetes, these drugs now treat heart failure and protect heart function.
Clinical Evidence: SGLT-2 inhibitors block the reabsorption of glucose in the kidneys, leading to increased glucose excretion. This process has been shown to improve heart function, reduce fluid overload, and protect the heart against further damage.
Large trials such as DAPA-HF and EMPEROR-Reduced have demonstrated that SGLT-2 inhibitors significantly reduce the risk of hospitalization and death from heart failure. They are now considered a cornerstone therapy for patients with heart failure with reduced ejection fraction (HFrEF).
