Beta-blocker therapy involves the use of medications that block beta-adrenergic receptors, reducing heart rate, blood pressure, and myocardial oxygen demand. This therapy is primarily used to manage cardiovascular conditions such as hypertension, angina, and heart failure, and can also be beneficial in treating anxiety and preventing migraines.

Heart rate is the number of times a person's heart beats per minute, reflecting the heart's ability to meet the body's demands for oxygen and nutrients. It is a crucial indicator of cardiovascular health and can be influenced by factors such as activity level, emotional state, and overall fitness.

Heart Rate

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.

Cardiovascular 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

Angina is a symptom of chest pain or discomfort that occurs when the heart muscle doesn't receive enough oxygen-rich blood, often due to narrowed or blocked coronary arteries. It is a warning sign of an increased risk of heart attack and requires medical evaluation and management to prevent serious cardiovascular events.

Angina

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.
