Study Notes

Cardiology: An Overview

Introduction to Cardiology

In the field of medicine, cardiology focuses on disorders related to the heart and vasculature. It involves diagnosing, treating, preventing, and managing various heart-related issues. Cardiologists specialize in maintaining heart health, providing comprehensive care for those suffering from cardiovascular diseases, while also contributing to research and development in the field.

Heart Anatomy Basics

At its core, the human heart is a muscular organ responsible for pumping blood throughout the body. Comprised of four chambers, it consists of the left and right atria and ventricles. Deoxygenated blood enters the right side via the superior and inferior vena cava, passes through the tricuspid valve into the right ventricle, and is then propelled into the lungs via the pulmonary artery. Once enriched with oxygen, oxygenated blood returns to the heart's left side through the pulmonary veins, passing through the bicuspid mitral valve into the left atrium. Lastly, oxygenated blood moves into the left ventricle, where it is pumped out of the heart through the aorta.

Cardiovascular Diseases

There are several types of cardiovascular diseases that can affect individuals differently. Some examples include arrhythmias, infective endocarditis, congenital heart defects, peripheral artery disease, aortic aneurysms, and venous thrombosis. Early detection and appropriate management are crucial for improving patient outcomes and reducing complications.

Electrocardiography (ECG)

An ECG is a non-invasive test used to evaluate the electrical activity of the heart. By placing electrodes on the skin, medical professionals can monitor and analyze the heart's rhythm patterns, making it an essential tool for diagnosing various cardiac abnormalities such as heart attacks, arrhythmias, and other forms of heart disease.

Heart Failure

Heart failure refers to the inability of the heart to effectively pump blood due to weakened muscle fibers or structural damage. Symptoms may include rapid breathing, fatigue, and shortness of breath. Treatment options range from lifestyle changes, medications, and advanced therapies like transcatheter aortic valve replacement (TAVR).

Interventional Cardiology

Interventional cardiologists specialize in performing minimally invasive procedures to treat heart-related issues. These non-surgical treatments include angioplasty and stent placement for blocked arteries, catheter ablation of irregular heartbeats, and transcatheter valve replacement.

As the field continues to evolve, advancements in cardiovascular medicine hold promise for better understanding, diagnosing, and managing various heart-related conditions.
