Cardiac implantable devices, including pacemakers and defibrillators, have revolutionized the management of heart rhythm disorders. These devices, which are surgically implanted to help regulate the heart's electrical system, play a crucial role in saving lives and improving the quality of life for millions of people worldwide. Although both pacemakers and defibrillators are used to address heart rhythm issues , they serve different functions and are tailored to treat specific heart conditions. This article examines the distinctions between pacemakers and defibrillators, their applications, and the technological advancements that continually enhance patient outcomes. Pacemakers: Restoring Normal Heart Rhythms A pacemaker is a small, battery-powered device that is implanted under the skin, typically near the collarbone. Its primary function is to help regulate slow heart rhythms, a condition known as bradycardia. When the heart’s natural pacemaker (the sinoatrial node) fails to gene...

Heart disease continues to be one of the most prevalent and deadly health conditions globally. As medical technology progresses, new treatments are emerging to offer better outcomes for patients. One such innovation is the biodegradable stent, a device designed to support arteries during recovery from a heart procedure temporarily. Unlike traditional metal stents, which remain in the body permanently, biodegradable stents gradually dissolve, offering unique advantages. In this article, we will explore the rise of biodegradable stents, their benefits, and the future they hold in heart disease treatment. What Are Biodegradable Stents? A biodegradable stent is a small, tube-like structure inserted into a blocked or narrowed artery to provide support during the healing process. It is typically used in procedures such as angioplasty, where the artery is dilated using a balloon catheter. Traditional stents are made of metals, such as stainless steel, and remain in the body indefinitely. How...

Cardiovascular disease (CVD) is a leading cause of illness and death among adults globally. This broad category includes various conditions that affect the heart and blood vessels, such as coronary artery disease, heart failure, arrhythmias, and stroke. Gaining a deeper understanding of how cardiovascular diseases are diagnosed, treated, and prevented is crucial for enhancing patient outcomes and mitigating the significant health burden associated with these disorders. The Landscape of Adult Cardiovascular Disease Cardiovascular disease in adults often stems from the gradual damage or dysfunction of the heart and vascular system. The most prevalent form, coronary artery disease, occurs when plaque accumulates inside the coronary arteries, limiting blood flow to the heart muscle and potentially causing chest pain or heart attacks. Other common cardiovascular conditions include hypertension, heart valve diseases, cardiomyopathy, and electrical disturbances of the heart, such as atrial f...
