Study Notes

Cardiovascular Conditions - Overview

Cardiovascular conditions encompass a wide range of diseases affecting the heart and blood vessels.
These conditions can vary significantly in severity and presentation, requiring diverse diagnostic and treatment approaches.
Factors such as age, lifestyle, genetics, and underlying medical conditions influence the likelihood and progression of cardiovascular ailments.

Angina Pectoris

Angina pectoris is characterized by chest pain or discomfort, typically triggered by exertion or stress.
The pain results from insufficient blood flow to the heart muscle, often due to coronary artery disease.
Symptoms range from mild pressure or tightness to severe crushing pain, potentially radiating to the arm, jaw, or back.
Stable angina is predictable, occurring with exertion and relieved by rest or medication.
Unstable angina presents as new or changing symptoms, increased severity, or occurrence at rest, and represents a critical medical concern.
Diagnosis entails a complete medical history, physical examination, and diagnostic tests like electrocardiography (ECG) and cardiac catheterization.
Management includes lifestyle modifications (e.g., diet, exercise), medication (e.g., nitrates, beta-blockers), and potentially procedures like coronary angioplasty or bypass surgery.

Pericarditis

Pericarditis is inflammation of the pericardium, the protective sac surrounding the heart.
It arises from various causes, including viral infections, bacterial infections, autoimmune disorders, or certain medications.
Symptoms commonly include sharp chest pain, worsened by deep breathing or lying down, accompanied by fever, fatigue, and shortness of breath.
A physical examination may reveal a friction rub, a distinctive sound indicative of inflammation.
Diagnostic procedures involve ECG, chest X-rays, and blood tests to identify the causative agent and assess the severity of inflammation.
Treatment focuses on managing symptoms, addressing the underlying cause, and preventing complications.

Heart Valve Disease

Heart valve disease encompasses a range of conditions affecting heart valves, hindering their normal function.
It can lead to narrowing (stenosis) or leakage (regurgitation) of blood flow through the valves.
Symptoms may include shortness of breath, fatigue, palpitations, and edema (swelling).
Diagnosis involves physical examination, echocardiography (ultrasound of the heart) to assess valve structure and function, and potentially cardiac catheterization.
Treatment varies based on the condition's type and severity. Mild cases may be managed medically, while severe cases may require surgical valve repair or replacement.

Arrhythmias

Arrhythmias are irregular heartbeats resulting from disturbances in the heart's electrical conduction system.
They can manifest as palpitations, dizziness, fainting, or shortness of breath; potentially leading to cardiac arrest.
Bradycardia (slow heart rate) and tachycardia (fast heart rate) are two principal types of arrhythmias.
Diagnosis often includes ECG monitoring over extended periods (e.g., Holter monitor) to detect precise rhythm disturbances.
Treatment options include medication, implantable cardiac devices (e.g., pacemakers, implantable cardioverter-defibrillators), or catheter ablation procedures.

Endocarditis

Endocarditis is an infection of the inner lining of heart chambers and valves (endocardium).
Common causative agents are bacterial infections.
Risk factors include pre-existing heart conditions, especially heart valve abnormalities.
Symptoms can be gradual or sudden, including fever, chills, fatigue, and new or changing heart murmurs.
Diagnosis involves blood cultures to identify the causative organism, echocardiography to detect valvular abnormalities, and ECG.
Treatment typically involves intravenous antibiotics administered for an extended period to eradicate the infection and prevent complications.
