  Pericarditis, an inflammatory condition affecting the pericardium - the thin sac-like membrane surrounding the heart, can be a source of acute chest pain and discomfort. While it is often idiopathic or without a known cause, pericarditis can also be triggered by various factors. Understanding these underlying causes is essential for accurate diagnosis, effective treatment, and prevention of recurrence. Ø   Viral Infections: One of the primary causes of pericarditis is viral infections, particularly those caused by the coxsackievirus and echovirus. These viruses can directly invade the pericardium, triggering an inflammatory response. The immune system's reaction to the viral presence can lead to the release of inflammatory chemicals, causing the pericardium to become irritated and inflamed. Ø   Bacterial Infections: While less common, bacterial infections can also result in pericarditis. Bacteria such as Streptococcus, Staphylococcus, and Mycobacterium tuberculosis can in

  Vitamin D, often referred to as the "sunshine vitamin," is crucial for maintaining bone health and regulating calcium levels. However, according to medical research it has significant impact on cardiovascular health also, specifically in protecting against heart failure. India’s leading cardiovascular surgeon Dr. Ramji Mehrotra says that Vitamin D's protective effect on the heart is due to several mechanisms. Firstly, it plays an important role in modulating the renin-angiotensin-aldosterone system (RAAS), which regulates blood pressure and fluid balance. Adequate Vitamin D levels have been associated with decreased activation of this system, resulting in lowered blood pressure and reduced strain on the heart. Moreover, Vitamin D exhibits anti-inflammatory properties. Chronic inflammation is a key contributor to the development and progression of heart failure. Vitamin D helps to mitigate inflammation by inhibiting the production of inflammatory cytokines and promo
