This is the final article of the mini-series, The Faces of Cardiovascular Disease, looking at the different presentations, symptoms, and root causes of a disease that affects millions of men and women around the world. Be sure to read part 1, 2, 3, and 4 here. In this final installment, we explore the latest research into the treatment and prevention of cardiovascular disease, with a look at what’s to come.
We started this series with a statistic: between 1980 and 2014, 4 in 10 deaths in the United States were a direct result of cardiovascular disease. This statistic obscures the fact that the risk posed by cardiovascular disease was far greater in 1980 than it was 34 years later. By 2014, fewer than 2.5 in every 10 deaths were attributed to cardiovascular disease.
What happened over those 34 years that led to improved outcomes? Two key components have been drug development and the adoption of healthier lifestyles; advances in these complementary areas have contributed to vastly reducing the number of people suffering from cardiovascular disease and improving the quality of life for those who are.
But that is only half the story; changing lifestyles also proved to be a major factor.
Exercise - what a revolution!! In the 70’s, if you were seen running or jogging something had better have been chasing you! But then came Jane Fonda, Arnold Schwarzenegger, Richard Simmons, and Charlene Prickett – the Health Hustle and Body Break with Hal and Joanne. Suddenly everyone was exercising and if you didn’t have leg warmers, you were NOT serious! Trends in diet were also changing around this time, focusing on heart healthy options. The USDA put out guides for healthy eating with the food wheel being released in 1984 and the pyramid in 1992. Use of tobacco products also declined precipitously as a critical eye was turned to what we put into our bodies.
Despite exponential progress in the prevention and management of cardiovascular disease, it remains the number one cause of death worldwide. What more can be done?
The quest continues by focusing on cardiovascular risk reduction. Current advances in research are unlocking the secrets of human longevity and wellness. Every day we develop a better understanding of how genetic, epigenetic, and lifestyle factors work in concert to tip the scales towards either health or disease.
The next generation of medicines will likely target a broader population or be more patient specific. Increasingly, chronic diseases, such cardiovascular disease, diabetes, chronic kidney disease, and dementia are considered to be varying manifestations of similar underlying processes. Yet, an individual’s genetic background can predispose them to disease susceptibility or to successful therapeutic intervention. Broadening our thinking on the nature of diseases and understanding their nuances opens up new doors for treatment.
The revolutionary advances that led to the halving in the rate of cardiovascular disease deaths between 1980 and 2014 have not been enjoyed by everybody. In poorer communities, and especially developing countries, with limited access to education and healthcare, these same kinds of improvements have yet to be seen. The greatest opportunities for reducing the burdens of cardiovascular disease may not lie in futuristic medicines, but in focusing on prevention, health promotion, and access to treatment.
Ultimately, the development of novel therapeutics, health promotion, disease prevention, and increased accessibility to lifesaving interventions have and will contribute to further reducing the risk of cardiovascular disease. Over the last 40 years, we have witnessed unprecedented success in reducing the burden of cardiovascular disease; the next 40 years are poised to surpass even this.
