Definition: Angiasthenia refers to a condition where one's heart rate, blood pressure, or heart beats are too low. Definition: A heart attack can cause angina pectoris or angitis, which is characterized by chest pain that often gets worse when lying down and might be severe enough to stop a person from doing work. This condition also often affects the lower body, making it difficult to walk, use the bathroom, and handle objects. The symptoms typically include fatigue, shortness of breath, nausea or vomiting, chest tightness or pressure, pain in the shoulder or arm, jaw muscles soreness, cold sweats, diarrhea, and weight loss (which can be associated with infection).
