Cardiovascular system also called as “circulatory system or blood vascular system”. It consists of heart, which is muscular pumping action, and closed system of blood vessels named as arteries, Veins, and capillaries
The main function of the cardiovascular system is transport oxygen and nutrients to the tissues and other organs in our body. Angiotensin is a peptide hormone that regulates blood pressure and maintains body fluids in the body. The main function of angiotensin is vasoconstrictor and increase blood pressure. Angiotensin system consists of two enzymes – Angiotensin1, Angiotensin2. Angiotensin 2 is used for heart strokes.
Hypertension can leads to heart diseases. High blood pressure causes thickening of the blood vessel walls. When combined with cholesterol it leads to deposition in the blood vessels. Insufficient oxygen supply to the heart leads to myocardial infraction.
Obesity can leads to hypertension and cardiovascular diseases. The risk of obesity in cardio vascular diseases involves changes in body composition that leads to alteration in heart structure.
Echocardiography is a cardiac test also called as “echocardiogram or cardiac echo”.
Echocardiography is a test that produces ultrasound of the heart; it is a type of medical imaging of the heart .The image is called “echocardiogram”.
Echocardiogram is used to know information about:
-
Blood clots in the heart chambers
-
Pressure in the heart
-
The image shows any problems that related to heart problems.
TYPES:
-
Transthoracic echocardiography
-
Trans esophageal Echocardiography
-
Stress echocardiography
-
Three dimensional echocardiography
-
Fetal echocardiography
CARDIAC CT:
Cardiac CT (COMPUTED TOMOGRAPHY) is a test that uses x-rays to get detailed information about our heart and blood vessels. It is a painless imaging test that provides 3-dimensional model of the whole heart.
MRI SCAN:
Magnetic resonance imaging scan is a type of body scan that uses radiology and powerful magnetic field to examine the whole body. MRI scan provides information about internal structure of the body. MRI scan gives information about:
-
Coronary heart diseases
-
Congenital heart failure
-
Heart stroke or heart attack
Track: 4 HEART FAILURE AND MYOCARDIAL INFRACTION
HEART FAILURE
Heart failure is chronic condition that result’s heart muscles are not able to pump enough blood to the body organs. Insufficient blood leads to poor oxygen supply to the body. It leads to “heart failure”.
TYPES OF HEART FAILURE:
-
Right –sided heart failure
-
Left –sided heart failure
-
Systolic heart failure
-
Diastolic heart failure
MYOCARDIAL INFRACTION
Myocardial infraction otherwise called as “HEART ATTACK”. Myocardial infraction occurs due to blockage of blood flow to the heart muscles. Myocardial infraction occurs when blood clot bocks the blood flow to the muscles, lack of blood, tissue loses oxygen and leads to “ISCHEMIA”.
SYMPTOMS:
-
Shortness of breath
-
Tightness in the neck, back or arms
-
fatigue
RESUSCITATIONS:
Cardiac pulmonary Resuscitation (CPR) is a life-saving technique and it is an emergency procedure that combines chest compression or providing artificial ventilation to the people who is in cardiac arrest or heart attack for restore spontaneous blood circulation.
TYPES OF CARDIAC PULMONARY RESUSCITATIONS:
-
High frequency chest compression
-
Prone CPR
-

Life-style changes
Heart transplantation also called as “cardiac transplant “. Heart transplantation is a surgery that performed on patients with last stage heart failures or coronary heart diseases.
Diseased heart is removed and replaces it with healthy heart from donor. Most hearts compulsory transplanted within 4 hours.
SOME COMPLICATIONS MAY OCCUR WITH HEART SURGERY, RISK OF HEART TRANSPLANTATION MAY INCLUDE:
-
Kidney failure
-
Bleeding
-
Infection after surgery
-
Breathing problems
-
Formation of blood clots
Genetics may influence the risk for developing cardiac diseases in many ways. A sudden change in gene (mutation) can leads to heart diseases.

Geriatric cardiology improved outcomes in health, social well-being, and care to adults.
Track: 11 CIRCULATION AND ARRYTHMIA
The circulation of heart involves three types:
-
SYSTEMIC CIRCULATION
-
CORONARY CIRCULATION
-
PULMONARY CIRCULATION
SYSTEMIC CIRCULATION: The process involved in systemic circulation is carried oxygenated blood from the left ventricle through the blood vessels of arteries and capillaries to the tissues of the body and returns deoxygenated blood through veins in the right atrium of the heart.
CORONARY CIRCULATION: Blood vessels supply blood to the heart muscles. Coronary arteries supply oxygenated blood to the heart muscles and coronary veins carries deoxygenated blood drains away from the tissue of the heart.
PULMONARY CIRCULATION: pulmonary circulation involves circulation of blood between heart and lungs.
ARRYTHMIA:
Irregular heart beat or improper heart beat i.e. too fast or too slow.
Arrhythmia is due to improper working of electrical impulse in heart.
SYMPTOMS: Chest pain, dizziness.
Electrophysiology study is a test that uses electrical system or activities used to detect abnormal heartbeats or arrhythmia.
Electrophysiology of heart involves using catheters placed into the heart and detects arrhythmia or abnormal heart beat.
RISK FACTORS:
-
Infection
-
Dizziness
-
Blood clots some times
Coronary heart disease is caused by formation of plaque in the walls of the arteries i.e. coronary arteries (the major blood vessel) or build-up of plaque in the walls of arteries. Plaque is made up of cholesterol or fat which causes narrowed arteries. It leads to insufficient blood supply to the heart.
SYMPTOMS:
-
Shortness of breath
-
Chest pain
-
Calcium channel blockers
-
Beta blockers
-
