Overview of most common cardiovascular diseases Ahmad Osailan
Objectives • Most common cardiac diseases • Signs and symptoms
Most common terms for symptoms of cardiac Disease • Dyspnea: Abnormally uncomfortable awareness of breathing. • PAROXYSMAL NOCTURNAL DYSPNEA: Interstitial or interalveolar pulmonary edema • Orthopnea: Inability to breath comfortably when lying. • Syncope: Loss of consciousness commonly from reduced perfusion to the brain. • Fatigue: Patient with impaired cardiovascular function • - decrease peripheral perfusion
What is Heart Disease • A general term that covers a number of diseases which affect the heart, including coronary artery disease, heart-failure and angina.
Cardiovascular diseases • ACQUIRED HEART DISEASE • CONGENITAL HEART DISEASES • VALVULAR HEART DISEASE • INFECTIVE ENDOCARDITIS • RHEUMATIC FEVER
Acquired Heart Diseases • ISCHAEMIC HEART DISEASE (CORONARY ARTERY DISEASE) • ANGINA PECTORIS • MYOCARDIAL INFARCTION • HYPERTENSION
CORONARY (ISCHAEMIC)HEART DISEASE Occurs when the coronary arteries that supply the heart muscle become blocked. • Partially blocked it causes angina. • Fully blocked it causes a myocardial infarction or a heart attack!
CORONARY (ISCHAEMIC)HEART DISEASE • CAUSE • Atherosclerosis: it is the accumulation of lipids in the arterial walls due to variety of factors. • It can lead to vascular thrombosis (clots)and result in embolism
CORONARY (ISCHAEMIC)HEART DISEASE • Signs and symptoms: • Cardiac ischemia in itself is symptomless. Its presence is manifested only by its dramatic complications namely:- • ANGINA PECTORIS • MYOCARDIAL INFARCTION • IHD often comes without warning or history of heart disease.
Angina Pectoris • It is a severe paroxysmal chest pain caused due to higher myocardial oxygen demand. • Cause: Partial blockage of coronary artery by atheroscelerosis.
Angina Pectoris • Signs and Symptoms: • Strangling, or tightness, • heaviness, • compression of the chest • Pain radiating to the left arm or jaw. • Exaggerated by physical exertion especially in cold weather and emotional stress. • Pain is relieved by rest
Myocardial infarction • when blood flow to a part of your heart is blocked for a long enough time that part of the heart muscle is damaged or dies.
MYOCARDIAL INFARCTION • Also called ( Heart attack ) • Signs and symptoms: • Strangling, or tightness, • heaviness, • compression of the chest • Pain radiating to the left arm or jaw. • Precipitated by physical exertion and emotional stress. • Pain is NOT relieved by rest. Unlike angina • Persist for a few hours if death does not supervene.
What differ Angina form MI • Signs and symptoms: • The pain of MI may sometimes start at rest and is not relieved by nitrates. • Vomiting, facial pallor • sweating, restlessness, apprehension are common. • Restlessness, cough , loss of consciousness may also occur.
HYPERTENSION • When either or both systolic or diastolic pressure are persistently raised, & on remeasurement , with systolic pressure >140 &diastolic >90 mm Hg
Features of advanced hypertension • SYMPTOMS • Headaches • Visual disorders • Tinnitus • Dizziness • Angina
CONGENITAL HEART DISEASE • Signs and symptoms: • Most striking feature: CYANOSIS • Passage of deoxygenated blood from the right ventricle directly into the left side of the heart & systemic circulation leads to chronic hypoxemia. Chronic hypoxemia causes severely impaired development & often gross clubbing of fingers & toes.
Clubbing • One of the most common Signs of congenital heart disease
Heart valves disease • Caused mainly by: • Infective endocarditis • Causative organisms: streptococci • It results from two main predisposing factors: • bacteraemia • cardiac lesion
Heart Valve diseases • Signs and symptoms: • Shortness of breath • Weakness or dizziness. • Discomfort in your chest. • Palpitations. This may feel like a rapid heart rhythm, irregular heartbeat, skipped beats or a flip-flop feeling in your chest. • Swelling of your ankles, feet or abdomen. This is called edema. Swelling may occur in your belly, which may cause you to feel bloated. • Rapid weight gain. A weight gain of two or three pounds in one day is possible.
HEART FAILURE • Heart failure is when the pumping actionof the heart is insufficient to meet the body¶s demand. • Signs and symptoms: • Shortness of Breath • Generalized Oedema • Easy fatigability
