Heart disease describes a range of conditions that affect the heart. Diseases under the heart disease includes blood vessel diseases, such as coronary artery disease; heart rhythm problems (arrhythmias); and heart defects you're born with (congenital heart defects), among others. Heart disease term is often used interchangeably with the cardiovascular disease. It generally refers to conditions that involve narrowed or blocked blood vessels that can lead to a heart failure, chest pain (angina) or stroke. Other heart conditions, such as those that affect your heart's muscle, valves or rhythm, also are considered forms of heart disease. Many forms of heart disease can be prevented or treated with healthy lifestyle choices.

Cardiac nursing is a nursing specialty which deals with the patients who suffer from various conditions of the cardiovascular system. Cardiovascular nurses handle the people with heart diseases and interact with their patients’ families. They may monitor and treat acutely ill patients, or they may focus on cardiac rehabilitation—helping patients make lifestyle changes to prevent the worsening of their disease.

Cardiovascular surgery is the main surgery on the heart vessels. It is employed to treat the complications of valvular heart disease, ischemic heart disease or to correct congenital heart disease from various causes, endocarditis, atherosclerosis and rheumatic heart disease. It also includes heart transplantation.

The interventional cardiology is the main branch of cardiology that refers the specific Cather based techniques to various structural heart diseases, non-surgical procedures for treating cardiovascular disease. Interventional cardiologists use catheters; it is thin, flexible tube to repair damaged vessels or other heart structures, often avoiding the need for surgery. The most commonly procedures can be perform on heart by Catheterization. It involves the insertion of a sheath into the femoral artery and cannulating the heart under X-ray visualization. Cardiac catheterization is a test which used to evaluate the coronary arteries and heart valve function.

Pediatric Cardiology is also called Pediatric Cardiopulmonary disease which involves the childhood disorder includes both the heart and lungs problems. Pediatric cardiologist is a pediatrician who has gotten broad preparing in diagnosis and treatment of kids' cardiovascular issues. Assessment and treatment may start with the embryo since heart issues can now be identified before birth.

Cardiovascular pharmacology is the main study of the effects of drugs on the entire cardiovascular system, which includes the heart and blood vessels.

Coronary heart disease is also known as the Coronary artery disease which means that the narrowing of the coronary arteries or it is a common term for the buildup of plaque inside the arteries which resize the coronary arteries. After the heart supplies blood with oxygen and nutrients, blood is carried by arteries to different body parts. The coronary arteries are vital: as coronary arteries carry blood to the heart muscle. So, when the coronary arteries become narrower then blood supply reduced to the heart muscles.

The regrowth of organs and tissues of the heart that are lost in an injury are called Cardiac Regeneration. This is in disparity to wound healing, which involves closing of the injury site by forming a scar. Few tissues like skin and large organs such as liver regrow quite readily, whilst others have been seen with little or no capacity of regeneration. Nevertheless in the present research, it suggests that particularly in the Lungs and heart, there is hope for a variety of organs and tissues will eventually develop and the capacity to regenerate.

Molecular Cardiology is the study of genetic heart disorders. It is a new and fast-growing area of cardiovascular medicine that aims to apply molecular biology techniques for the mechanistic investigation, diagnosis, prevention and treatment of cardiovascular disease. Gene analysis and transgenic techniques have provided a new understanding of cardiovascular disease pathogenesis.

Cardiac remodeling or Ventricular remodeling is generally accepted as a determinant of the clinical course of heart failure (HF). It defines as genome expression resulting in molecular, cellular and interstitial changes and manifested clinically as changes in shape, structure, size, and function of the heart. Cardiac remodeling can happen as a result physiological remodelling or pathological remodeling (injury to the heart muscle) and from cardiac load or injury, cardiac remodeling is influenced by hemodynamic load, neurohormonal activation. Congenital heart disease, chronic hypertension, with intra-cardiac shunting, and valvular heart disease may also lead to remodeling. Mostly the cardiac myocyte is the major cell involved in cardiac remodeling. Due to this, the myocardial necrosis (cell death) and disproportionate thinning of the heart occurs.

The Vascular Biology exists as a wide-ranging discipline that includes study of vascular function, structure, growth as well as development.  This field comprises investigation at essentially all levels, including studies of molecules, cells, organs also intact organisms.  Perturbations of vascular function be there involved in various pathophysiological states, with neoplasia, inflammation, aging, neurological diseases, metabolic disorders pulmonary diseases also hypertension.

Myocardial infarction (MI) or acute myocardial infarction (AMI), is the medical name for a heart attack. Myocardial infarction occurs when the flow of the blood stops to a part of the heart causing damage to the heart muscle. This is usually the result of a blockage in one or more of the coronary arteries. A blockage can develop due to a buildup of plaque, a substance mostly made of cholesterol, fat, and cellular waste products and the other risk factors are like smoking, obesity, diabetes, alcohol intake, high blood pressure and poor diet etc. Aspirin is an appropriate immediate treatment for a suspected myocardial infarction.

High blood pressure is also called hypertension and it is a serious medical condition. It happens when the force of the blood pumping through your arteries is too strong. Blood pressure is the force exerted by the blood against the blood vessels walls, and the magnitude of this force only depends on the cardiac output and the resistance of the blood vessels. The high blood pressure usually does not cause any symptoms but the long term high blood pressure, however, is a major risk factor for stroke, coronary artery disease, peripheral vascular disease, heart failure, vision loss, and chronic kidney disease. Hypertension can strain the heart, damage blood vessels, kidney problems, and increase the risk of stroke, heart attack, and death.

Cardiology is the branch of medicine which deals with the dysfunctions of the heart in humans or animals. The field includes diagnosis and treatment of heart failure, congenital heart defects, coronary artery disease, valvular heart disease and electrophysiology. It is a specialization of Physicians and internal medicine that specialize in this field of medicine are called cardiologists.  The Cardiothoracic surgeons or Cardiac surgeons are the ones who specialize in cardiology from general surgery. Clinical Cardiology an American journal about Cardiology founded in 1978. Clinical Cardiology forum which helps in coordinating the researches in medical diagnosis, cardiovascular medicine and cardiovascular surgeries.

Heart rhythm issues commonly called heart arrhythmias happens when the electrical motivations that arrange the heartbeats don't work appropriately, bringing about the heart to pulsate too quick, too moderate or unpredictably. Heart arrhythmias may feel like a vacillating or hustling heart and might be safe. Some heart arrhythmias may bring about annoying now and then even life-debilitating indications and signs. Heart arrhythmia treatment can regularly control quick, moderate or sporadic heartbeats. Likewise, in light of the fact that troublesome heart arrhythmias are frequently provoked or are even brought on by a harmed heart or frail, the person might have the capacity to lessen your arrhythmia hazard by receiving a heart-sound way of life.

Cardiomyopathy is a most common group of diseases that affect the heart muscles. In this, the heart muscle becomes rigid, enlarged or thick. In this condition, heart is less able to circulate the blood to all the body parts and maintain a normal electrical rhythm. This can lead to heart failure or irregular heartbeats called arrhythmias. In turn, heart failure can cause fluid to build up in the legs, ankles, lungs, feet or abdomen. The Typical perilous danger in patients with cardiomyopathies is sporadic heart rate.

The demonstrative tests in cardiology are techniques for determining the  heart conditions connected with sound versus unfortunate, pathologic, heart capacity. Numerous intrusive and noninvasive tests can depict cardiovascular structure and capacity. Additionally, medications can be regulated amid certain intrusive indicative tests (e.g, percutaneous coronary intercession amid heart catheterization, radiofrequency removal amid electrophysiologic testing).

Cardiology is the main part of medicine dealing with dysfunctions or malfunctioning and disorders of the heart. Heart is an important muscular organ that pumps blood to the body via circulatory system. Drugs that are used to treat all the disorders in body have a great impact on heart causing various adverse effects. Therefore, case reports on diseases and cardiac arrest  have a great significance and help in development and advancing of treatment strategies. 20^th European Cardiology conference or rather all conferences of cardiology help in networking, B-2-B partnering between academicians and professionals.
