Cardiovascular changes refer to the physiological and pathological alterations in the heart and blood vessels that occur due to aging, disease, or lifestyle factors. These changes can affect cardiac output, blood pressure, and overall cardiovascular health, influencing the risk of conditions such as hypertension, atherosclerosis, and heart failure.

Physiological alterations

Pathological alterations

Heart and blood vessels

Aging is a complex biological process characterized by the gradual decline in cellular and physiological functions, leading to increased vulnerability to diseases and ultimately death. It is influenced by genetic, environmental, and lifestyle factors, and is a major focus of scientific research aiming to extend healthspan and lifespan.

Aging

A disease is when your body isn't working the way it should, and it can make you feel sick or hurt. Sometimes diseases can spread from one person to another, like when you catch a cold from a friend.

Disease

Lifestyle factors encompass the daily habits and behaviors that significantly impact an individual's overall health and well-being. These factors include diet, physical activity, sleep, stress management, and substance use, all of which can influence the risk of developing chronic diseases and affect longevity.

Lifestyle Factors

Cardiac output is the volume of blood the heart pumps per minute and is a critical indicator of cardiovascular health. It is determined by the heart rate and stroke volume, reflecting the heart's efficiency in delivering oxygen and nutrients to tissues.

Cardiac Output

Blood pressure is the force exerted by circulating blood on the walls of blood vessels, crucial for maintaining adequate circulation throughout the body. It is typically expressed as two numbers, systolic and diastolic pressures, which represent the pressure during heartbeats and between beats, respectively.

Blood Pressure

Overall cardiovascular health

Risk of conditions

Hypertension, or high blood pressure, is a chronic medical condition where the force of the blood against the artery walls is consistently too high, potentially leading to serious health complications like heart disease and stroke. It is often asymptomatic, earning it the nickname 'the silent killer,' and requires regular monitoring and management through lifestyle changes and medication.

Hypertension

Atherosclerosis is a condition characterized by the buildup of plaque inside the arteries, leading to reduced blood flow and increased risk of cardiovascular diseases. It involves complex interactions between lipids, inflammatory cells, and the arterial wall, and is influenced by lifestyle factors and genetic predispositions.

Atherosclerosis

Heart failure is a chronic condition where the heart is unable to pump blood effectively to meet the body's needs, often leading to fatigue, shortness of breath, and fluid retention. It is a progressive disease that can result from various underlying conditions, such as coronary artery disease, hypertension, or cardiomyopathy, and requires careful management to improve quality of life and outcomes.
