Quit smoking and limit alcohol consumption
Cardiovascular diseases (CVDs) stand as the world's leading cause of death, claiming approximately 17.9 million lives annually, according to 2019 data from the World Health Organization (WHO). These diseases account for a staggering 32% of global deaths, with 85% of these fatalities resulting from heart attacks and strokes. Most alarmingly, the burden of CVDs falls disproportionately on low- and middle-income countries, highlighting a stark global health inequity.
Understanding Cardiovascular Diseases
CVDs encompass a range of disorders affecting the heart and blood vessels, including:
- Coronary heart disease: Blockages in the blood vessels supplying the heart muscle.
- Cerebrovascular disease: Disruptions in blood flow to the brain, leading to strokes.
- Peripheral arterial disease: Restricted blood flow to the limbs.
- Rheumatic heart disease: Damage from untreated streptococcal infections.
- Congenital heart disease: Structural heart abnormalities present at birth.
- Deep vein thrombosis and pulmonary embolism: Dangerous blood clots in the veins.
These diseases often manifest suddenly as acute events like heart attacks or strokes, triggered by blockages due to fatty deposits or, in some cases, bleeding in the brain.
Risk Factors: What Drives the Epidemic?
The key drivers of CVDs are well-documented:
- Behavioural factors: Unhealthy diets, lack of physical activity, tobacco use, and harmful alcohol consumption.
- Environmental factors: Air pollution significantly increases the risk of heart and vascular conditions.
- Intermediate risks: Indicators like high blood pressure, elevated blood glucose, and obesity signal a heightened risk of severe outcomes like heart attacks or strokes.
In addition to these factors, broader determinants like poverty, urbanization, and stress compound the challenge, especially in resource-limited settings.
Addressing Prevention: A Shared Responsibility
The good news is that most cardiovascular diseases are preventable. Measures that can significantly reduce risks include:
- Quitting tobacco use.
- Reducing salt intake and consuming more fruits and vegetables.
- Engaging in regular physical activity.
- Avoiding excessive alcohol consumption.
- Advocating for policies that improve air quality and promote healthy lifestyle choices.
Healthcare systems must focus on early detection and management of risk factors like hypertension, diabetes, and high cholesterol. Universal access to essential medicines, including aspirin, statins, and beta-blockers, alongside affordable diagnostic technologies, is crucial.
Challenges in Low- and Middle-Income Countries
More than 75% of CVD-related deaths occur in low- and middle-income countries. Factors such as inadequate access to healthcare, late-stage detection, and limited availability of essential medicines exacerbate the problem. Additionally, CVDs impose significant financial burdens on households and economies, perpetuating cycles of poverty.
Innovative Interventions and Global Goals
The WHO's Global Action Plan for the Prevention and Control of Noncommunicable Diseases (2013–2020) outlines ambitious targets to combat CVDs:
- Reduce raised blood pressure prevalence by 25% by 2025.
- Ensure 50% of eligible individuals receive preventive drug therapy and counselling for heart attacks and strokes.
- Achieve 80% availability of affordable essential medicines and technologies for NCDs in healthcare facilities.
Reaching these targets demands stronger health systems, investment in public health infrastructure, and innovative policies to tackle the root causes of CVDs.
A Call to Action
The fight against cardiovascular diseases is not just a medical challenge but a global development priority. Governments, healthcare providers, and individuals must work together to implement preventive measures, improve access to care, and ensure that resources are directed to those most in need.
Cardiovascular diseases may be the leading cause of death today, but with concerted effort, they do not have to be the leading cause of death tomorrow.
