Introduction In recent years, drugs like tirzepatide and semaglutide, originally developed for diabetes, have captured global attention for their remarkable weight-loss effects. But scientists are now discovering that the benefits of these medicines extend far beyond the bathroom scale. New studies are revealing powerful effects on the heart, liver, and overall metabolism, suggesting that GLP-1 receptor agonists could reshape the way we treat some of the most common chronic d

Most people think of heartbreak as an emotional ache — something that hurts but eventually fades away. Yet for some, intense stress or grief can literally break the heart. Known as stress-induced cardiomyopathy, or "broken heart syndrome," this rare condition causes the heart muscle to suddenly weaken after a shock, like losing a loved one or experiencing extreme fear. Though it often looks like a heart attack, the cause isn't a blocked artery but the body's own stress respo

While melatonin is widely considered a benign over-the-counter sleep aid, a recent large observational study suggests that chronic use (≥12 months) may be associated with a significantly increased risk of incident heart failure, hospitalisation, and mortality in adults with insomnia. These findings—presented at the American Heart Association (AHA) Scientific Sessions 2025—raise important questions about the long-term cardiovascular safety of melatonin. Given the study’s obs

What is Pulmonary Hypertension? Pulmonary Hypertension (PH) is a disease in which the blood vessels connecting the heart and the lungs develop high blood pressure. This can lead to fluid congestion in the lungs and dysfunction of the right side of the heart, known as Right Heart Failure. Symptoms of Pulmonary Hypertension Symptoms of PH vary from person to person, but commonly include the following: Shortness of Breath (worse with exercise or lying flat) Fatigue Dizziness/lig

The first Sunday in November traditionally marks the end of daylight-saving time. In the United States, clocks are turned back one hour to standard time. This change results in a gain of an hour of daylight at the start o

The Problem: A Heart That Can't Heal Itself Heart disease remains one of the world’s top killers, largely because the human heart has almost no natural ability to repair itself. When heart tissue is damaged, like after a heart attack, the lost cardiomyocytes (the muscle cells that make the heart beat) do not grow back. As a result, many patients face long-term heart failure, and even transplants are limited by donor shortages and rejection risks. Stem Cells Enter The Picture

Pulmonary Arterial Hypertension (PAH)  is a rare condition characterized by high blood pressure in the pulmonary arteries. The pulmonary arteries are the blood vessels that carry blood from the right side of the heart to the lungs. The increased blood pressure can cause blood to back up in the right side of the heart. The right ventricle stretches like a water balloon, crowding out the left ventricle, making that smaller and less effective at pumping blood. A backup of blood

What is a heart attack? A heart attack is also known as a Myocardial Infarction. It is due to blockage to the flow of blood that brings oxygen to a part of the heart muscle. If the heart muscle is not fixed quick enough, the heart muscle will begin to die. Affecting factors Age Lifestyle Habits Other medical conditions can be some of the reasons to a heart happening. Symptoms Chest and upper body pain Shortness of breath Dizziness Sweating Nausea (National Heart, Lung and Blo

What is myocardial infarction?   A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow to the heart muscle (the myocardium) is suddenly blocked, most often by a blood clot. An MI can sometimes go unnoticed, but it may also lead to severe complications such as hemodynamic deterioration—an inadequate supply of oxygen to the body’s organs—or even death. The primary cause of myocardial infarction is coronary artery disease, though genetic factors

Every 40 seconds, someone in the United States has a heart attack or stroke. Yet the most remarkable fact about heart disease is this: more than 80% of premature heart disease and strokes are preventable. Despite this, cardiovascular disease remains the leading cause of death worldwide, claiming more lives each year than all cancers combined. Why is there such a gap between what we know and what we do? The answer lies in how our healthcare system, and often individuals themse

Gestational hypertension is characterized by blood pressure equal to or greater than 140/90 mmHg. It increases risks for both the baby and the mother, such as preterm birth, organ damage, and placental abruption. The diagnosis is made when symptoms such as headaches, swelling, and vision changes are accompanied by blood pressure readings consistently at 140/90 mmHg or higher. Gestational hypertension affects 8-10% of all pregnancies. Studies show that hypertension disorders c

By: Nesredin Hassen Yesuf LinkedIn  | Email Introduction Hypertension, often described as the “silent killer,” remains one of the most important global health challenges of the 21st century. Affecting more than 1.28 billion adults worldwide, hypertension is both a leading cause of cardiovascular disease and a critical driver of chronic kidney disease (CKD) [1,2]. The relationship between blood pressure and renal health is bidirectional: uncontrolled hypertension damages the k

Hypertension, or high blood pressure, is a common cardiovascular condition heavily correlated with hearing loss, although the exact mechanism is not fully understood. Early diagnosis of hypertension can help with early testing and management of hearing loss.

Prenatal yoga is more than gentle stretching but a science-backed practice that supports cardiovascular health, reduces anxiety, shortens labor, and enhances maternal resilience. Grounded in evidence from recent clinical studies, this guide explores how mindful movement benefits both mother and baby, outlines safety tips based on ACOG recommendations, and presents key modified poses for every trimester.
