Cardiovascular Diseases comprise a group of disorders of the heart and circulation that is characterized by high morbidity and mortality rates globally. Such diseases include coronary artery disease that leads to heart attacks, cerebrovascular disease which leads to strokes, and peripheral artery disease that affects blood flow to the limbs. There are other types of CVDs for example, heart failure in which the heart is incapable of pumping blood and arrhythmias which is a disturbance of the heartbeat. There are several modifiable and non-modifiable risk factors which predispose an individual to CVDs, they include; hypertension, high cholesterol, diabetes, smoking, obesity and lack of exercise. Prevention and management include change of behavior, use of drugs, and in serious cases, surgery.
Cardio-Oncology is a specialty care that is dedicated to the relationship between heart disorders and cancer therapy. Since cancer treatments like chemotherapy and radiation are toxic to the cardiovascular system, cardio-oncology focuses on the early identification of such issues and their management. This field deals with the interaction of cardiologists, oncologists and other practitioners in order to provide complete care to a cancer patient including their cardiovascular health. Specific focus in cardio-oncology includes assessment of the heart during cancer therapy, management of cardiovascular diseases before cancer treatment and studying on how to avoid cardiovascular problems in cancer patients.
Pediatric Cardiology is a sub-discipline of cardiology that deals with the diagnosis and management of cardiac disorders in children. This is diseases that affect children at birth and those that develop at some point during their childhood, for instance, congenital heart diseases. Some of the conditions that may be managed by pediatric cardiologists include: the basic congenital anomalies that need continuous observation to severe cases which require surgery. The aim of pediatric cardiology is to provide the child with the best quality of life that he or she can have knowing that he or she has a heart problem.

Fetal Cardiology deals with the diagnosis and treatment of heart diseases in the unborn child (fetuses) during pregnancy. Fetal cardiologists are able to diagnose congenital heart defects as well as other anomalies in the fetal heart using imaging techniques such as fetal echocardiography. This is because early diagnosis enables planning of the right care as well as interventions to be made during pregnancy, during delivery and even after the baby is born hence improving the outcome of babies who are affected.

This sub-discipline guarantees the treatment of the cardiovascular system and developing fetus of women with the consideration of peculiarities.
Diabetes, Obesity, and Stroke are interconnected health issues that significantly impact cardiovascular health.

Diabetes is a chronic disorder characterized by high blood glucose levels that can cause long-term damage to blood vessels and neurons. Diabetes patients are more likely to develop atherosclerosis (artery narrowing) and other vascular problems, which increases their chance of having a stroke. Obesity: Being overweight is a significant risk factor for a variety of health issues, including cardiovascular disease and stroke. Stroke: A medical emergency in which blood flow to a portion of the brain is disrupted, resulting in brain damage. Uncontrolled diabetes, obesity, high blood pressure, smoking, and high cholesterol all increase the risk of a stroke.

The interaction of diabetes, obesity, and stroke emphasizes the significance of a comprehensive approach to cardiovascular health, with an emphasis on prevention and treatment techniques to lower risk and improve outcomes.
