Reproduction of previous documented angina, Known history of coronary artery disease, including myocardial infarction, New transient mitral regurgitation, hypotension, diaphoresis, pulmonary edema or rales, New or presumably new transient ST-segment deviation (> 0.05 mV) or T-wave inversion (> 0.2 mV) with symptoms, Elevated cardiac troponin T or I, or elevated CK-MB, ST-segment elevation greater in lead III than in lead II, ST-segment elevation of > 2.5 mm in lead V, ST-segment depression of > 1 mm in leads II, III, and aVF, ST-segment depression of 1 mm or ST-segment elevation in leads II, III, and aVF, Measured 4 hours after onset of chest pain, Measured 10 hours after onset of chest pain. Cardiol J. We hypothesized that he had myocardial ischemia due to increased oxygen demand from uncontrolled GERD symptoms. 1994 Oct;24(4):888-92. doi: 10.1016/0735-1097(94)90846-x. He also denied any nausea, vomiting, or epigastric discomfort. Four patients staffed by one full-time nurse; 4. Linked to ventricular remodeling, elevated cTn in HF should not be discarded as false positive as the prognosis associated with elevated cTn in this setting is poor.7, An important non-ACS diagnosis to consider in a patient presenting with chest pain and elevated cTn is acute aortic dissection (AAD). Rapezzi, C., et al., Risk factors for diagnostic delay in acute aortic dissection. 32, no. Accessibility J. P. Liuzzo and J. Common examples of underlying causes of non-MI troponin elevation include: Some underlying conditions can cause a type 2 MI or a non-MI troponin elevation depending on the clinical context. Y. Liu, S. He, Y. Chen et al., Acid reflux in patients with coronary artery disease and refractory chest pain, Internal Medicine, vol. Chauhan et al. Becattini, C., M.C. The .gov means its official. In a study by Dobrzycki et al., 50 patients with angiographically proven CAD underwent simultaneous continuous ECG and esophageal pH monitoring for 24 hours to assess for ST-segment depression episodes and total duration of ischemic episodes [11]. Thus, it is critically important to recognize this association and initiate treatment with PPIs in appropriate patients with CAD and concomitant GERD as it might improve GERD and prevent future adverse cardiac events. Patients at intermediate risk may be monitored in a telemetry bed in an inpatient setting or a chest pain unit. Vasospastic angina, which was previously referred to as Prinzmetal [ 1] or variant angina, is characterized by episodes of rest angina that promptly respond to short-acting nitrates and are attributable to coronary artery vasospasm. Shave, R., et al., Exercise-Induced Cardiac Troponin Elevation: Evidence, Mechanisms, and Implications. Mohammed, A.A. and J.L. Acute (on chronic) systolic or diastolic heart failure: Usually due to acute ventricular wall stretch/strain. Abnormal Q waves usually develop within the first day, and T-wave inversion and normalization of ST segments occur within hours to days. Occasionally, reciprocal ST-segment depression occurs in leads that are electrically opposite to the area of injury. amyloidosis), systemic hypertension, left ventricular hypertrophy, HF, pulmonary hypertension and chronic kidney disease (CKD).28. A Practical Approach to Invasive Testing in Ischemia With No Obstructive Coronary Arteries (INOCA). University of Florida, Gastroesophageal Reflux Disease, Office of Medical Informatics. Type 2 MI is defined as "myocardial infarction secondary to ischaemia due to either increased oxygen demand or decreased supply, e.g. Isolated small Q waves in leads II, III, and aVF (in the electrically vertical heart) and leads I and aVL (in the electrically horizontal heart) frequently are normal. This is an open access article distributed under the, http://www.worldgastroenterology.org/assets/downloads/pdf/wdhd/2008/events/map_of_digestive_disorders_2008.pdf, http://www.niddk.nih.gov/health-information/health-statistics/Pages/digestive-diseases-statistics-for-the-united-states.aspx. GERD is caused by an impaired antireflux barrier and defective lower esophageal sphincter, leading to reflux of gastric acid into the esophagus. Elevated cTn values outside of ACS are not uncommon and reflect cardiomyocyte necrosis from a wide array of cardiac, pulmonary and systemic diseases. CR524CR529, 2004. 14446, Lippincott-Raven, Philadelphia, Pa, USA, 4th edition, 2009. Gastroesophageal reflux disease , also known as GERD, is a digestive disorder that affects the ring of muscle between your esophagus and stomachthe lower esophageal sphincter, or LES. Of these, 2,344 patients (3.3% overall, or 7.0% of those that had a cTn measured) had an elevated cTn concentration. Squeezing pain in your chest. Serum cardiac marker determinations play a vital role in the diagnosis of acute myocardial infarction. spasm Bastiany A, Pacheco C, Sedlak T, Saw J, Miner SES, Liu S, Lavoie A, Kim DH, Gulati M, Graham MM. 20 Patients with a normal CK-MB level but Morrow, and P. Jarolim, Earlier detection of myocardial injury in a preliminary evaluation using a new troponin I assay with improved sensitivity. An official website of the United States government. The serum CK level rises within three to eight hours after myocardial injury, peaks by 12 to 24 hours, and returns to baseline within three to four days.16 A serum CK level may be used as a screening test to determine the need for more specific testing. Troponin: Elevated troponin levels can indicate heart damage or even a heart attack. The most common signs and symptoms include: Skin changes. Biomarker Development in Cardiology: Reviewing the Past to Inform the Future. Most low-risk patients may undergo early exercise testing or can be discharged with careful outpatient follow-up. The rash, which can be itchy and painful, is often the first sign of dermatomyositis. Of 218 episodes of ST-segment depression, 45 (20.6%) correlated with pathologic reflux. Although GERD classically presents with symptoms of heartburn and regurgitation of food contents, some patients may present with less typical extraesophageal cardiac or respiratory symptoms. However, the CK-MB subform assay is not yet widely available. 2018 Jan;33(1):17-24. doi: 10.1007/s00380-017-1029-9. Physical exam did not reveal evidence of heart failure, wheezing, or crackles. Merck Manual Professional Version. The lab has to be taken in the context of the patients presentation and other supporting findings. According to National Digestive Disease Information Clearinghouse (NDDIC), 20% of the population had reflux symptoms at least once a week in 2004; 8.9 million ambulatory visits in 2009 and 4.7 million hospitalizations in 2010 were attributed to GERD [3]. The pain is often intense, and you might mistake it for heart pain, also known as angina. Sometimes an antidepressant, such as imipramine (Tofranil), may be prescribed. They happen only National Library of Medicine Ohlmann, P., et al., Diagnostic and prognostic value of circulating D-Dimers in patients with acute aortic dissection. Chui Man Carmen Hui and Santosh K. Padala contributed equally to the paper and share first authorship. This widely available marker has low sensitivity and specificity for cardiac damage. and J.J. van de Leur, Elevated troponin T concentrations in critically ill patients. Accessed Oct. 8, 2020. While cTn elevation in CKD necessarily leads to a higher risk for false positive ACS diagnosis, cTn values in this setting are to be taken seriously; a true positive cTn related to ACS in patients with CKD is associated with a heightened risk for mortality29 compared to non CKD patients, while an asymptomatic elevation in cTn in severe CKD is associated with an increased incidence of ACS30 and a 2- to 5-fold increase in mortality.31 Serial measurement, observing for a rise and/or fall of an elevated cTn value in a patient with CKD is recommended to differentiate ACS from non-ACS causes of cTn elevations. Januzzi, Jr., Clinical applications of highly sensitive troponin assays. doi: 10.1371/journal.pone.0271189. In type 2 MI, myocardial injury occurs secondary to an underlying process, and therefore requires correct documentation of the underlying cause as well. Coronary vasospasm (positive ergonovine provocation test) could explain 74% of elevated cTnI levels in patients with insignificant coronary stenosis. Only about 2 percent of patients with cocaine-associated chest pain have acute coronary syndrome.4. 2023 American College of Cardiology Foundation. Troyanov, S., et al., Diagnostic specificity and prognostic value of cardiac troponins in asymptomatic chronic haemodialysis patients: a three year prospective study. 5, pp. Can Troponin Be Elevated Without Heart Attack J Am Coll Cardiol. He denied any associated palpitations, dizziness, nausea, vomiting, or epigastric abdominal pain. Vital signs on admission revealed blood pressure of 146/95mmHg, pulse of 90bpm, respiratory rate of 18 per minute with 100% O2 saturation on 2L of oxygen via nasal cannula. Accessed Oct. 6, 2020. 11, pp. 167173, 2005. M. Swiatowski, B. Jacek, M. Klopocka et al., Suppression of gastric acid production may improve the course of angina pectoris and the results of treadmill stress test in patients with coronary artery disease, Medical Science Monitor, vol. Thompson PD, Klocke FJ, Levine BD, Van Camp SP. Subsequently, patient underwent an early invasive strategy of cardiac catheterization and angiography that revealed chronic, severe, native 3-vessel CAD (Figures 1(a) and 1(b)). Some patients may present without chest pain; in one review,2 sudden dyspnea was the sole presenting feature in 4 to 14 percent of patients with acute myocardial infarction. Unlike troponin I levels, troponin T levels may be elevated in patients with renal disease, polymyositis, or dermatomyositis. Melanson, S.E., D.A. It is well known that pain can cause an increase in myocardial oxygen demand through enhanced adrenergic activity with increased heart rate and blood pressure [9]. Wallace, T.W., et al., Prevalence and determinants of troponin T elevation in the general population. 15, no. A 71-year-old male with a history of coronary artery disease presented to the ED with complaints of acute chest pain and respiratory 1, pp. HHS Vulnerability Disclosure, Help A more recent article on acute coronary syndrome is available. For our patient, high dose of PPI was initiated to control his reflux symptoms along with further optimization of medical therapy for his CAD in order to augment efforts at secondary prevention of future ischemic events. Troponin test Gastroesophageal reflux disease (GERD) is a common gastrointestinal disorder with increasing prevalence worldwide. The same study5 demonstrated that patients presenting with sharp or stabbing pain, pleuritic pain, and positional chest pain had only a 3 percent likelihood of having acute coronary syndrome. doi: 10.7759/cureus.26193. However, these same conditions could cause a non-MI troponin elevation in patients without CAD and could also cause myocardial injury and troponin release by causing acute left ventricular stretch/strain. Accessed Oct. 6, 2020. Pain radiating to the shoulder, left arm, or both arms somewhat increases the likelihood of acute coronary syndrome (likelihood ratio [LR]: 1.6).3, Typical angina is described as pain that is substernal, occurs on exertion, and is relieved with rest.
