The terrifying truth about heart disease, which continues to be one of the leading causes of serious illness and death, is that it develops quietly – for years, even decades, before making itself known. By then, the damage is often irreversible.
Many people remain unaware of the risk for years, often not realising they are at risk of a heart attack or stroke until they are already in an ambulance. Regular screenings can dramatically lower the risk and save lives, says pharmacist Thabo Lephalala of Medipost Pharmacy. He warns that the common belief that heart disease presents obvious early signs is a major barrier to prevention.
“Heart disease is often silent in its early stages. By the time symptoms appear, there may already be significant damage to the arteries,” says Lephalala. “That is why early screening and proactive management are so important. We need to identify risk before it becomes a crisis.”
Heart diseases are caused by risk factors such as age, genetics, high blood pressure, high cholesterol and lifestyle behaviour such as smoking, all of which can damage the delicate lining of the arteries.
Over time, the body responds by forming plaque, a build-up of fat, calcium and inflammatory material that narrows and stiffens the arteries. If plaque becomes unstable and ruptures, it can trigger a clot that blocks blood flow to the heart or brain, causing a heart attack or stroke.
"The arteries are designed to be smooth and flexible,” Lephalala explains. “When that lining is repeatedly damaged, plaque gradually builds up, restricting blood flow and increasing the risk of blockage.”
Routine screening through simple checks – blood pressure readings, cholesterol tests and blood glucose screening – can identify risks long before a crisis occurs.
“You do not need complex diagnostics to spot early warning signs,” Lephalala notes. “Basic routine checks performed consistently can highlight risk before complications develop.”
Treatment can slow progression and, in some cases, partially reverse damage. Medicines such as statins help stabilise plaque, while blood pressure medication reduces strain on the arteries. However, long-term adherence is often a challenge, as patients often stop medication once they feel better or if they encounter side effects or financial obstacles.
“Consistency is what protects the heart over time,” says Lephalala. “A pill organiser, a daily routine and open communication with a healthcare professional can make a real difference.” Consider lifestyle changes which may include healthy eating, regular exercise, quitting smoking, and managing stress to reduce the chances of heart disease.
“Medication helps control the condition, but lifestyle changes address the cause,” Lephalala emphasises. “The two must work together.”
Heart disease is not written in stone. While genetics play a role, the biggest common risk factors, smoking, lack of exercise or movement, eating poorly, carrying extra weight, high blood pressure, cholesterol, and chronic stress, are entirely within our control. Small, consistent changes to daily habits, combined with early screening and treatment when needed, can prevent most cases or greatly change the outcome for those already at risk.
Certain supplements can help protect your heart, with omega-3 fatty acids, coenzyme Q10, magnesium, and vitamin D offering supportive benefits. However, these should only be taken under medical supervision due to possible interactions with prescription medications. “It is essential to keep your healthcare professional informed of any adjustments you wish to make,” Lephalala warns.
“This is where Medipost Pharmacy's expertise comes in. We offer services in 11 official languages to address any challenges you might face. We provide nationwide delivery of chronic medications, such as statins and blood pressure treatments, with delivery included at no additional cost to our clients.
“Heart disease is largely preventable. With early detection, the right treatment and healthy lifestyle choices, people can protect their hearts and their lives,” Lephalala concludes.
