Cardiovascular Disease Epidemiology and Risk Factors: General Concepts Peter P. Toth

Introduction Cardiovascular disease (CVD) is epidemic throughout the world and includes atherosclerotic disease in its various forms (coronary artery disease [CAD], peripheral arterial disease, carotid artery disease), hypertension, stroke, and heart failure, among others. CVD is the leading etiology for global mortality and the most important source of morbidity. The most significant clinical sequelae of CVD include myocardial infarction (MI), both hemorrhagic and ischemic stroke, claudication and lower limb loss, chronic kidney disease and end-stage renal disease, heart failure, arterial aneurysm formation in the aorta and its tributaries, and, especially for patients with diabetes mellitus (DM) and/or hypertension (HTN), retinopathy and nephropathy. The diagnosis and management of CVD incurs enormous economic costs upon society worldwide and is responsible for considerable disability throughout all regions of the world [1, 2]. The World Heart Federation estimates that over 17.3 million people die of CVD annually, and by 2030 that number is expected to increase to 23 million people [3]. This represents 31% of all deaths annually. The World Health Organization estimates that 85% of deaths due to CV occur from MI and stroke [4].

In the United States, the American Heart Association estimates that: [1] CVD accounted for 840,678 deaths in the US in 2016, equal to approximately 1 of every 3 deaths [2]. CVD mortality exceeded all forms of cancer and chronic lower respiratory disease combined [3]. Between 2013 and 2016, 121.5 million American adults were afflicted with some form of CVD. [4] Between 2014 and 2015, direct and indirect costs of CVD and stroke amounted to $351.2 billion ($213.8 billion in direct costs and $137.4 billion in lost productivity/mortality) [5]. In 2016, CAD was the leading cause (43.2%) of deaths attributable to cardiovascular disease in the US, followed by stroke (16.9%), HTN (9.8%), heart failure (9.3%), diseases of the arteries (3.0%), and other cardiovascular diseases (17.7%) [6]. CVD and stroke accounted for 14% of total health expenditures in 2014–2015. This is more than any major diagnostic group [7]. In addition, total direct medical costs of CVD are estimated to increase to $749 billion in 2035, according to a 2016 study [5]. This chapter focuses on cardiovascular epidemiology. Epidemiology quantifies the distribution and determinants of health and disease. More specifically, epidemiologic investigation evaluates associations between exposures to specific genetic, environmental, and behavioral features and the risk for developing disease or maintaining health. After seven decades of research conducted within large prospective longitudinal cohorts around the world, risk factors for the development of CVD are biologically plausible and have been firmly established. Prospective, double-blind, randomized clinical trials testing specific interventions to treat these risk factors have also established that they are either treatable or reversible, and that these actions reduce risk for CVD. Cardiovascular epidemiology has made possible the prevention of some types of CVD events in the primordial, primary, and secondary prevention settings.

Global Perspective of Cardiovascular Disease Subsequent to World War II, it became clear that efforts to reduce the incidence of CVD were urgently needed. In the United States the Framingham Heart Study (FSH) was initiated in 1948 with the inclusion of 5209 men and women in the original cohort that was free of CVD at baseline [6, 7]. Being a prospective, longitudinal cohort observed over many years, the temporal relationship between numerous risk factors and the incidence (new cases of specific forms of CVD within a defined time frame) as well as causation of disease could be established in a study such as the FHS. The FHS established dyslipidemia, hypertension, diabetes, smoking, and other genetic and behavioral features as risk factors for the development of CVD. In subsequent decades the FHS also evolved an Offspring cohort, a Third-Generation cohort, and a Spouses cohort, all which continue to yield novel insight into the genesis of CVD. The Seven Countries Study lent support to many of the most important conclusions reached by the FHS [8, 9]. In the US numerous other cohorts exploring features that predispose to CVD were also introduced, including the Cardiovascular Health Study, [10] the Atherosclerosis Risk in Communities Study (ARIC), [11] the Multiethnic Study of Atherosclerosis (MESA), [12] Reasons for Geographic and Racial Differences in Stroke Study (REGARDS), [13] and the Jackson Heart Study

(JHS), [14] among others. Similar cohorts were recruited in Europe, [15, 16] South America, [17] Asia, [2, 18–20] India, [21] Africa, [22] and elsewhere [23, 24]. The INTERHEART Study evaluated CVD risk factors in 52 countries and affirmed that nearly 92% of risk for an MI is attributable to treatable/preventable risk factors and that risk factors behave similarly in peoples from around the world [25]. The pooling of data has allowed for the generation of global maps depicting the prevalence of specific forms of CVD, such as ischemic heart disease (IHD. (Fig.  1.1). It is a

easily discerned that IHD is widely prevalent in all nations and continents and that Eastern Europe, the Middle East, the Indian Subcontinent, and Northern Africa are particularly impacted by IHD.

Risk Factors for Atherosclerotic Disease Dyslipidemia Low-Density Lipoprotein After nearly 100 years of experimental investigation, low-density lipoprotein cholesterol (LDL-C) is indisputably established as atherogenic [26]. LDL particles are the most abundant in serum and are scavenged in the subendothelial space by activated macrophages [27]. Lipid-laden macrophages are an important substrate for atheromatous plaque formation and provide pro-inflammatory stimuli to propagate plaque and ultimately render it unstable and prone to rupture, leading to the development of acute tissue ischemia in affected vascular territories [27–29]. There is a log-linear relationship between LDL-C and risk for CAD. (Fig.  1.2.) There is unequivocal evidence that lowering LDL-C with statins (3′-hydroxymethyl-glutaryl coenzyme A inhibitors) [30] and other drugs such as ezetimibe [31] and proprotein convertase/subtilisin kexin type-9 inhibitors [32, 33] beneficially impact risk for acute cardiovascular events (Fig. 1.3). A relatively novel means by which to view the relationship between LDL-C and risk for CAD-related events is by assessing life years of exposure to specific serum levels of this lipoprotein [34]. The higher the level and the longer the exposure, the higher the risk for developing CHD. By lowering LDL-C earlier and more and more aggressively, the age at which an acute CV event may be expected to occur is extended to older and older ages (Fig. 1.4) [34, 35]. Hence, time is of the essence since limiting exposure to LDL-C is akin to limiting exposure to an established
