Karachi: Cardiovascular disease continues to be the leading cause of death worldwide, claiming approximately 19 million lives annually. In a recent podcast hosted by the Preventive Cardiovascular Nurses Association, Dr. Salim Virani, Vice Provost of Research at the Aga Khan University, offered insights into the evolution of heart health over the past 30 years and projected future challenges.

Dr. Virani highlighted a concerning trend where high-income countries have experienced a decrease in heart disease and stroke mortality, while low- and middle-income regions, including South Asia and sub-Saharan Africa, are witnessing an increase. He attributed this disparity to weaker healthcare systems, limited access to medications, and insufficient preventive screening in these regions.

The podcast also touched upon the impact of climate change and air pollution on cardiovascular health. Dr. Virani pointed out that environmental factors like air quality and temperature extremes significantly affect heart health, emphasizing that these are not merely ecological issues but critical health concerns.

Dr. Virani stressed the importance of early prevention, citing evidence that maternal health affects lifelong heart outcomes. He suggested that addressing conditions such as high blood pressure and diabetes during pregnancy could lead to better cardiovascular health for future generations.

To achieve lasting progress, Dr. Virani emphasized the need to address the root causes of poor heart health, including poverty, education, and inequity. He called for collective action, noting that heart disease is a societal issue requiring comprehensive solutions.

The insights shared in the podcast underline the urgent need for global efforts to tackle cardiovascular disease by focusing on prevention, addressing environmental factors, and reducing healthcare disparities.
