Symptoms usually include one or more of the following: orthopnea (difficulty breathing while lying flat), dyspnea (shortness of breath) on exertion, pitting edema (swelling), cough, frequent night-time urination, excessive weight gain during the last month of pregnancy (1-2+ kg/week; two to four or more pounds per week), palpitations (sensation of racing heart-rate, skipping beats, long pauses ...
[27] [28] [29] High troponin T levels have also been reported in patients with inflammatory muscle diseases such as polymyositis or dermatomyositis. [30] [31] Troponins are also increased in rhabdomyolysis. In hypertensive disorders of pregnancy such as preeclampsia, elevated troponin levels indicate some degree of myofibrillary damage. [32] [33]
Differential diagnosis of troponin elevation includes acute infarction, severe pulmonary embolism causing acute right heart overload, heart failure, myocarditis. Troponins can also calculate infarct size but the peak must be measured in the 3rd day. After myocyte injury, troponin is released in 2–4 hours and persists for up to 7 days.
Seen as elevated troponin and inflammation on imaging Since myocarditis is often due to a viral illness, many patients experience symptoms consistent with a recent viral infection including a fever, rash, loss of appetite, abdominal pain, vomiting, diarrhea , joint pains , and easily becoming tired.

High sensitive troponin I test can help to proactively identify individuals at high cardiovascular risk long before symptoms appear. [21] [22] The higher the troponin I level in asymptomatic individuals, the higher the likelihood of subclinical myocardial injury. It provides greater accuracy in identifying persons at low CVD risk. [22] [21]
Signs and symptoms of pregnancy are common, benign conditions that result from the changes to the body that occur during pregnancy. Signs and symptoms of pregnancy typically change as pregnancy progresses, although several symptoms may be present throughout. Depending on severity, common symptoms in pregnancy can develop into complications. [1 ...
Troponin T binds to tropomyosin and helps position it on actin, [2] and together with the rest of the troponin complex, modulates contraction of striated muscle. [3] The cardiac subtype of troponin T is especially useful in the laboratory diagnosis of heart attack because it is released into the blood-stream when damage to heart muscle occurs. [4]
Variant angina should be suspected by a cardiologist when a) an individual's symptoms occur at rest or during sleep; b) an individual's symptoms occur in clusters; c) an individual with a history of angina does not develop angina during treadmill stress testing (variant angina is exercise tolerant); d) an individual with a history of angina ...
