"Cardiovascular Diseases Most cardiovascular diseases can be prevented by addressing behavioral risk factors such as tobacco use, unhealthy diet and obesity, physical inactivity and harmful use of alcohol using population-wide strategies. People with cardiovascular disease or who are at high cardiovascular risk (due to the presence of one or more risk factors such as hypertension, diabetes, hyperlipidemia or already established disease) need early detection and management using constant monitoring, counselling and medicines, as appropriate.
High Blood Pressure (Hypertension)
High blood pressure (hypertension) affects 20% of the general population and up to half of all individuals, 70 years of age and older. Approximately one billion people currently have high blood pressure, and this number is expected to increase by more than fifty percent by the year 2025. Worldwide hypertension is the third leading cause of death and hypertension-related deaths are expected to rise drastically in the coming decades. High blood pressure places stress on the cardiovascular system. The strain on the heart leads to enlargement of cardiac chambers and causes damage to the blood vessels that supply the heart. In the peripheral circulation, the increased pressure in the vessels can cause intracranial bleeding and can damage vital organs, including the liver, kidneys, brain, and lungs.
Despite all of these health factors, hypertension is often considered “the silent killer” because most patients with high blood pressure do not feel the effects and therefore might not seek treatment until it is too late."
