Facts About Cardiovascular Disease Everyone Should Know

Cardiovascular disease (CVD) is the leading cause of death globally, affecting millions of people every year. The World Health Organization estimates this number at 17.9 million people.

Often, people don’t know they have CVD until they experience a major event like a heart attack or stroke, which account for more than four out of five CVD-related deaths.

Understanding some key facts is a crucial step toward prevention and better health management.

Fact #1:

"Heart disease" is often used interchangeably with CVD, but CVD is a broader term that includes diseases of both the heart and blood vessels (veins and arteries). CDV is responsible for more deaths worldwide than any other cause. 

Fact #2:

The most common forms of CVD include coronary artery disease (which can lead to heart attacks), cerebrovascular disease (strokes), heart failure and arrhythmias (irregular or abnormal heartbeats).

Fact #3:

‍While men are often thought to be more at risk, CVD is the leading cause of death for women as well. It affects people of all ages, genders and ethnicities. Key risk factors include high blood pressure, high cholesterol, smoking, diabetes, obesity, poor diet and physical inactivity. Some factors like age and family history also play a role but can't be controlled. 

Fact #4:

Symptoms of CVD can range from chest pain or discomfort to shortness of breath, fatigue, dizziness and swelling in the legs or ankles. Strokes can cause sudden numbness, confusion or trouble speaking. Women may experience different or more subtle symptoms than men, especially during a heart attack. These symptoms include shortness of breath without chest pain, nausea or vomiting and back, neck or jaw pain. 

Fact #5:

Early detection of a CVD-related health event is possible. Data collected by Apple smart watches and iPhones can be used to calculate individual risk in real time and predict when and how changes in health states may occur. Notifying patients of imminent danger enables timely intervention by healthcare providers, paving the way for personalized medical intervention and treatment. 

The risks of many cardiovascular diseases can be reduced through lifestyle changes such as regular exercise, a balanced diet, avoiding smoking and managing stress. Regular check-ups and monitoring of blood pressure and cholesterol can also help. Understanding these facts can help in recognizing the risks and taking steps to improve heart health.
