Heart inflammation comes in several forms. Two of these forms are myocarditis and pericarditis. Myocarditis is the most common condition of the two, and roughly 1.5 million cases occur annually around the globe. Its cause is most often a viral infection. Pericarditis, on the other hand, is incredibly rare. Making up only 0.1% of hospital admissions, pericarditis is an inflammation of the sac that surrounds the heart. Both viral and bacterial infections can cause it, as well as heart surgery. Symptoms of heart inflammation include mild chest pain or pressure and heart palpitations.
