Hello, I understand and appreciate your question. Brief Answer: Thrombocytopenia is associated with cardiovascular problems. Detailed Answer: If your blood platelet count falls below normal, you have thrombocytopenia. Thrombocytopenia is a common problem in cardiovascular patients, particularly those who are in critical care units. Thrombocytopenia is a condition characterized by abnormally low levels of thrombocytes. Patients with thrombocytopenia had more episodes of major bleeding, increased incidence of acute kidney injury, and infection like staph infection. Atherosclerosis, aortic stenosis, or other vascular pathologies that predispose to heightened platelet consumption. Alternatively, right-sided heart failure (associated with hepatic congestion and resultant hypersplenism) could predispose to low platelet count levels. Discomfort in jaw maybe is a sign of angina pectoris. Thank you for asking your query on health care magic. If you have more questions, feel free to ask. Thank you. Kind regards.
