In the latter part of the 20th century, drug development in cardiovascular diseases (CVDs) was a paragon of “modern” therapeutics, bringing about a substantial number of effective, well-tolerated agents targeting some of the most prevalent diseases of the Western world. These drugs were often examples of rational drug development targeting specific pathophysiologic pathways previously elucidated through basic research (e.g., targeting of the renin-angiotensin system or the cholesterol synthesis pathway). The widespread adoption of these ground-breaking medications in practice and into medical guidelines undoubtedly played a role in the fall of morbidity and mortality from CVD in the United States in recent decades. For instance, the combined, age-adjusted rates of death due to heart disease and CVD fell in the United States from an aggregate of 329.6 per 100,000 in 1999 to 203.5 in 2014. Although lifestyle trends (e.g., decreased smoking prevalence) contributed to this decline, the impact of safe and effective medications for common CVD conditions cannot be dismissed. Yet, despite the drop in CVD morbidity and mortality, CVDs remain a leading cause of morbidity and mortality in the United States and, therefore, a large area of unmet medical need.
