Study Notes

Hypertension

Hypertension, indicated by blood pressure readings of 140/90 mmHg or higher over two consecutive readings, is a significant risk factor for many cardiovascular disorders, including kidney disease
The prevalence of hypertension is high, affecting one in three American adults
Its direct and indirect costs amount to $46 billion annually
Primary hypertension is idiopathic, its cause unknown, but lifestyle factors and inflammatory responses likely play a role
Secondary hypertension, caused by another chronic condition.
Specific factors contributing to hypertension: excessive secretion of vasopressin and angiotensin II, smoking, renal disease, and adrenal disorders

Treatment

Effective treatment aims to minimize risk of CVD and renal disease by lowering blood pressure to appropriate levels
A comprehensive plan includes: weight reduction, physical activity, nutrition therapy, and pharmacological interventions such as loop diuretics, thiazides, carbonic anhydrase inhibitors, and potassium-sparing diuretics

Cardiovascular Disease

Cardiovascular diseases (CVD) are the leading cause of death in the United States
An estimated 92.1 million adults in the US live with one or more forms of CVD
The annual costs of CVD, both direct and indirect, amount to $316 billion
The age-adjusted CVD death rate has significantly decreased over the past 40 years due to advancements in treatment and preventive measures

Major Forms of Cardiovascular Disease

Major forms include hypertension, atherosclerosis, ischemic heart disease, peripheral vascular disease, and heart failure

Anatomy and Physiology of the Cardiovascular System

The cardiovascular system plays a crucial role in regulating blood flow to tissues, transporting oxygenated blood and nutrients, removing waste products, and engaging in thermoregulation, hormone transport, fluid volume maintenance, pH regulation, and gas exchange.
The heart, a crucial organ of the cardiovascular system, has three layers: epicardium (outer), endocardium (inner), and myocardium (middle, responsible for muscle contraction)
The heart has four chambers: two upper chambers (left and right atria), and two lower chambers (left and right ventricles).
The electrical activity of the heart originates at the sinoatrial (SA) node and can be measured using an electrocardiogram (ECG).

Atherosclerosis

Atherosclerosis is a thickening of the blood vessel walls due to the presence of plaque and a loss of vascular elasticity, causing a constriction in blood flow, and increasing the risk of myocardial infarction (MI), cerebrovascular accident (CVA; stroke), peripheral vascular disease (PVD), coronary heart disease (CHD), and congestive heart failure (CHF) in severe cases.

Atherosclerosis: Epidemiology

About 630,000 Americans die from heart disease annually with coronary heart disease being the leading cause
Heart disease remains the leading cause of death for most racial and ethnic groups in the United States
The annual cost to the United States associated with heart disease is about $329 billion

Atherosclerosis: Pathophysiology

Atherosclerosis is a complex process that involves endothelial cells, smooth muscle cells, platelets, and leukocytes
It begins as a response to endothelial lining injury, triggering an inflammatory process, and eventually constricting arterial blood flow.

Atherosclerosis: Risk Factors

Atherosclerosis risk factors work additively, meaning their individual contributions combine to increase the overall risk.
Family history of heart disease, age and sex (more prevalent in people over 65, with males developing it at a faster rate), obesity, dyslipidemia (lipids transported via lipoproteins), and certain factors like diabetes, smoking, low physical activity, and hypertension all contribute to the risk of atherosclerosis.
