49 Possible Causes for Acute Myocardial Infarction, Cardiomegaly, Pulsus Alternans

  • Cardiomyopathy

    Electrocardiogram showed right axis deviation, poor R-wave progression, and diffuse ST-segment elevation in the anterior leads, and cardiomegaly was observed by roentgenogram[ncbi.nlm.nih.gov] Acute myocarditis may clinically mimic an acute myocardial infarction with chest pain.[radiologyassistant.nl] In very few people with cardiomegaly and severe congestive heart failure, a heart transplant may be recommended.[m.webmd.com]

  • Heart Failure

    Pleural effusion and cardiomegaly were observed. A laboratory analysis revealed anemia with iron deficiency and elevated human parvovirus B19 (B19V) immunoglobulin M.[ncbi.nlm.nih.gov] alternans (alternating large and small pulse pressures) and a raised JVP.[patient.info] […] on Management of Acute Myocardial Infarction).[doi.org]

  • Congestive Heart Failure

    Autopsy showed mild cardiomegaly with microscopic foci of myocardial fibrosis and extensive contraction band necrosis.[ncbi.nlm.nih.gov] alternans (alternating large and small pulse pressures) and a raised JVP.[patient.info] […] failure acute myocardial infarction angina pectoris cardiac arrest cardiovascular disease chest pains congestive heart failure coronary coronary infarction coronary thrombosis[thesaurus.com]

  • Acute Myocarditis

  • Ischemic Cardiomyopathy

    Pulmonary venous congestion No cardiomegaly No or mild cardiomegaly Hemodynamics Normal or high EDP, low EF, diffusely dilated hypokinetic ventricles AV valve regurgitation[merckmanuals.com] The patient was subsequently readmitted with an acute myocardial infarction, and the coronary angiogram again failed to demonstrate significant stenosis.[ncbi.nlm.nih.gov] Related: Enlarged heart (cardiomegaly): Causes, symptoms, diagnosis and treatment Silent heart attack (silent ischemia): Symptoms, causes, and treatments [adstoappear][belmarrahealth.com]

  • Bacterial Myocarditis

    Cardiomegaly and diminished systolic function occur due to myocardial damage. Typical signs of CHF occur which may progress to shock,arrythmias and sudden death. 6.[slideshare.net] As with viral myocarditis, this disease can present with signs and symptoms of acute myocardial infarction, complicating the diagnosis.[ncbi.nlm.nih.gov] Narula J, et al: Recognition of acute myocarditis masquerading as acute myocardial infarction. NEJM 1993;328:100–104.[karger.com]

  • Hypersensitivity Myocarditis

    CXR: Normal cardiac silhouette but pericarditis or overt clinical congestive heart failure is associated with cardiomegaly. Vascular redistribution.[patient.info] In one case, death was directly attributed to myocarditis; in the second case, the patient died of an acute myocardial infarct, but myocarditis may have played a contributory[ncbi.nlm.nih.gov] Her pulse was weak and thready, and she had an enlarged, tender liver, cardiomegaly, and S 3 and S 4 gallops.[nejm.org]

  • Secondary Cardiomyopathy

    Common abnormalities seen on the chest radiograph include cardiomegaly, interstitial edema, pleural effusion(s), and evidence of previous sternotomy (sternal wires).[clevelandclinicmeded.com] Aneurysmal subarachnoid hemorrhage may induce Takotsubo cardiomyopathy that can present as an acute ST-elevation myocardial infarction.[link.springer.com] A comparison of immediate angioplasty with thrombolytic therapy for acute myocardial infarction. ‎[books.google.es]

  • Myocardial Fibrosis

    Therefore, most of these cases may be a sequela of myocarditis, and more correctly termed post-myocarditic cardiomegaly.[link.springer.com] Increased syndecan-4 levels were previously detected after acute myocardial infarction and in subjects with heart failure.[ncbi.nlm.nih.gov] Myocardial Gd-DTPA kinetics determine MRI contrast enhancement and reflect the extent and severity of myocardial injury after acute reperfused infarction .[nature.com]

  • Dilated Cardiomyopathy

    Chest radiograph showed cardiomegaly; electrocardiogram showed left ventricular hypertrophy and echocardiography revealed dilated cardiomyopathy.[ncbi.nlm.nih.gov] Pulsus alternans is an infrequent, complex pathophysiologic sign often associated with severe heart failure.[ncbi.nlm.nih.gov] Research is underway into progenitor cell therapy following initial pilot trials of intracoronary stem cell infusion in acute myocardial infarction.[patient.info]
