  • Troponin
  • As it is only one of the many potential causes of chest pain, the patient usually has a number of tests in the emergency department, such as a chest X-ray, blood tests (including myocardial markers such as troponin I or T, and H-FABP and/or a D-dimer if a pulmonary embolism is suspected), and telemetry (monitoring of the heart rhythm). (wikipedia.org)
  • Commonly used blood tests include troponin and less often creatine kinase MB. (wikipedia.org)
  • heart
  • This study was undertaken to determine whether adaptations to short-term exercise training after myocardial infarction, could affect the response of heart rate, blood pressure and double product at submaximal workload, and the behavior of electrocardiographic ST segment depression.

  • Two methods are currently FDA-cleared to perform MTWA testing in the U.S., namely, the Spectral Method, which was developed by Cohen and Smith at M.I.T. and was commercialized by Cambridge Heart, and the Modified Moving Average (MMA) method, which was developed by Nearing and Verrier at Harvard Medical School, Beth Israel Deaconess Medical Center, and is commercialized by GE Healthcare. (wikipedia.org)
  • The Spectral Method requires a specialized exercise protocol and proprietary electrodes and washout of beta-adrenergic blocking agents to allow the patient to achieve a target heart rate of 105-110 beats/min. (wikipedia.org)
  • This test can be used to diagnose coronary artery disease (also known as ischemic heart disease) and assess patient prognosis after a myocardial infarction (heart attack). (wikipedia.org)
  • A stress test may also use an echocardiogram (ultrasonic imaging of the heart) or a nuclear stress test (in which a radioisotope is injected into the bloodstream). (wikipedia.org)
  • Showing the relative amounts of radioisotope within the heart muscle, the nuclear stress tests more accurately identify regional areas of reduced blood flow. (wikipedia.org)
  • In 2013, in its "Exercise Standards for Testing and Training", the AHA indicated that high frequency QRS analysis during ECG treadmill test have useful test performance for detection of coronary heart disease. (wikipedia.org)
  • The common approach for stress testing by American College of Cardiology and American Heart Association indicates the following: Treadmill test: sensitivity 73-90%, specificity 50-74% (Modified Bruce protocol) Nuclear test: sensitivity 81%, specificity 85-95% (Sensitivity is the percentage of sick people who are correctly identified as having the condition. (wikipedia.org)
  • Exercise temporarily increases the rate, but lowers resting heart rate in the long term, and is good for heart health. (wikipedia.org)
  • Well-trained athletes can have much larger hearts due to the effects of exercise on the heart muscle, similar to the response of skeletal muscle. (wikipedia.org)
  • This causes a lack of oxygen and blood to the heart, which can result in a myocardial infarction (heart attack). (wikipedia.org)
  • This test is painless and it helps detect insufficient blood flow to the heart. (wikipedia.org)
  • This test can also detect any thickening in the walls of the left ventricles as well as any defects in the electrical impulses of the heart. (wikipedia.org)
  • A stress test, is just that, a test to put stress on the heart through exercise. (wikipedia.org)
  • This test uses an ECG to detect the electrical impulses of the heart during physical exertion. (wikipedia.org)
  • Clinically, creatine kinase is assayed in blood tests as a marker of damage of CK-rich tissue such as in myocardial infarction (heart attack), rhabdomyolysis (severe muscle breakdown), muscular dystrophy, autoimmune myositides, and acute kidney injury. (wikipedia.org)
  • Myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to a part of the heart, causing damage to the heart muscle. (wikipedia.org)
  • Play media Myocardial infarction (MI) refers to tissue death (infarction) of the heart muscle (myocardium). (wikipedia.org)
  • There is a weak relationship between severity of pain and degree of oxygen deprivation in the heart muscle (i.e., there can be severe pain with little or no risk of a myocardial infarction (heart attack) and a heart attack can occur without pain). (wikipedia.org)
  • As these may precede a heart attack, they require urgent medical attention and are, in general, treated in similar fashion to myocardial infarction. (wikipedia.org)
  • segment
  • Effect of precordial electrocardiographic electrode placement on ST-segment measurement during exercise. (biomedsearch.com)
  • This investigation sought to determine the influence of varying precordial electrocardiographic (ECG) electrode placement on the detection of exercise-induced ST-segment shifts. (biomedsearch.com)
  • rhabdomyolysis
  • Exertional rhabdomyolysis (ER) - sometimes called exercise-induced rhabdomyolysis - is the breakdown of muscle from extreme physical exertion. (wikipedia.org)
  • Exertional rhabdomyolysis, the exercise-induced muscle breakdown that results in muscle pain/soreness, is commonly diagnosed using the urine myoglobin test accompanied by high levels of creatine kinase (CK). (wikipedia.org)
  • submaximal
  • Twenty-six volunteers underwent a submaximal or symptom-limited cardiopulmonary exercise testing (CPET) on a cycle ergometer and were divided into AMI group (AMIG=12, 56.33±8.65 years) and healthy group (CG=14, 53.33±3.28 years). (scielo.br)
  • In addition, a history of MI and the summed difference score independently predicted submaximal exercise. (medpagetoday.com)
  • underwent
  • Of those who took the test, 12% subsequently underwent bypass grafts surgery compared with 14% of those who did not (p greater than .05). (ahajournals.org)
  • Predictor
  • Being able to exercise was the strongest independent predictor of survival compared to any form of pharmacologic stress," they concluded. (medpagetoday.com)
  • chest
  • A chest radiograph and routine blood tests may indicate complications or precipitating causes and are often performed upon arrival to an emergency department. (wikipedia.org)
  • Chest pain is the most common symptom of acute myocardial infarction and is often described as a sensation of tightness, pressure, or squeezing. (wikipedia.org)
  • They may also cause chest pain, a faint feeling, fatigue, or hyperventilation after exercise. (wikipedia.org)
  • severe
  • BALTIMORE -- The ability to perform a stress exercise test strongly predicts survival, but an inability to complete the test may be diagnostic for severe disease, according to two Brazilian studies. (medpagetoday.com)
  • typically
  • Because V̇ o 2max typically is achieved by exercise that involves only about half of the total body musculature, it is generally believed that V̇ o 2max is limited by maximal cardiac output rather than peripheral factors. (ahajournals.org)
  • Typically, a radiotracer (Tc-99 sestamibi, Myoview or thallous chloride 201) may be injected during the test. (wikipedia.org)
  • Risks
  • Risks that lead to ER include exercise in hot and humid conditions, improper hydration, inadequate recovery between bouts of exercise, intense physical training, and inadequate fitness levels for beginning high intensity workouts. (wikipedia.org)
  • relation
  • This study sought to determine the relation between the magnitude of exercise-induced ST depression and the ischemic burden as determined by quantitative thallium-201 scintigraphy. (biomedsearch.com)
