Cardiology deals with the study and treatment of disorders of heart and blood vessels. In Greek words cardia means heart and logy means study of. It is one of the branches of medicine and the physicians who specialized in this field are cardiologists. The way in which heart processes oxygen and nutrients in the blood is the basic function of cardio...
View MoreCardio vascular surgery is performed by cardiologists on heart and blood vessels. Cardiologist is a doctor who specialized in finding, diagnosing, preventing and treating of heart diseases. Cardio vascular surgeries are generally done to correct heart valve problems, replacement of diseased heart and restore the blood flow. It includesOpen heart su...
View MoreHeart attack occurs when there is a blockade of blood flow to the heart and it is a medical emergency. It is also called as acute myocardial infarction. One of the most causes of heart attack is atherosclerosis which prevents blood from getting to the heart muscle. The blockade is formed in heart attack is either due to plaque or fat, cholesterol a...
View MoreHypertension is defined as high blood pressure which is a long term force of blood against the artery walls. Blood pressure is determined both by the amount of resistance to blood flow in arteries and the amount of blood that heart pumps. If more amount of blood is pumped it narrows the arteries, high blood pressure. Blood pressure is represented b...
View MoreIschemia restricts the blood supply to the tissues due to damage or dysfunction of tissue causing shortage of oxygen which is needed for cellular metabolism. If damage occurs to the cardiac muscle it is called as Myocardial Ischemia or Cardiac Ischemia. It reduces the blood flow to the heart by partial or complete blockade of coronary arteries. It ...
View MoreArteritis is characterized by inflammation in the walls of arteries. It is caused by damage to blood vessels which reduces blood flow to the organs. It occurs either due to infection or autoimmune response. Major types of arteritis include:Takayasu arteritis: It is an inflammatory disease effects mainly on large vessels such as aorta and its branch...
View MoreCardiomyopathy is a disease of heart muscle. The muscle becomes enlarged, thick and rigid. It is either acquired or hereditary. If the disease worsens the heart becomes weaker and it is unable to pump blood throughout the body and it even causes arrhythmias. The main types of cardiomyopathy are:Dilated CardiomyopathyHypertropic CardiomyopathyArryth...
View MoreAngioplasty is a surgical procedure to open the blocked artery that supply blood to the heart muscle and restores the blood flow to the heart. The blocked artery is opened by inflating a tiny balloon into it. So it is known as balloon angioplasty. This procedure is also called as percutaneous transluminal coronary angioplasty or percutaneous corona...
View MoreVentricular septal defect is generally referred as hole in the heart. It is an abnormal opening between the ventricular septum. Ventricular septum is a wall which divides left and right ventricles of the heart. The hole may vary in size from pin to complete absence of ventricular septum. It is most often seen at birth but it occurs in adults after ...
View MorePacemaker is a small device which uses electrical pulses to prompt the heart to beat at a normal rate. It is placed in the chest or abdomen to control abnormal heart rhythms. Most common reasons for pacemaker recommendation are bradycardia and heart block. Bradycardia is a type of arrhythmia in which the heart beats slower than normal. Heart block ...
View MoreCardiac arrest is a serious heart condition. It is an abrupt loss of blood flow to the heart. It is triggered by an electrical malfunction in the heart which causes arrhythmia. With its pumping action disrupted, the heart cannot pump blood to brain, lungs and the person lose consciousness and the pulse declines. If the victim does not receive treat...
View MoreCongenital is a defect in the structure of heart. It is a type of birth defect. The defect involves the arteries, veins, valves of heart, wall of the heart. The causes of congenital heart diseases are genetic, environmental or a combination of both. The disease is classified as either cyanotic congenital heart disease or acyanotic congenital heart ...
