Pulsus Alternans: Causes & Reasons

Possible Causes for Pulsus Alternans

Once heart dysfunction sets in, signs of cardiac failure may manifest, such as pulmonary edema (fluid accumulation in the lungs), peripheral oedema, hypoxemia, pulsus alternans [medindia.net]

Alcoholic Cardiomyopathy

Leg elevation promptly reversed the pulsus alternans, and the echocardiographic abnormality. [ncbi.nlm.nih.gov]

Application of a small dose of glyceryl trinitrate paste (0.25 in) resulted in severe left ventricular dysfunction with the appearance of pulsus alternans in a patient with [ncbi.nlm.nih.gov]

Signs There may be a tachycardia at rest, low systolic blood pressure (BP), a displaced apex (LV dilatation) or RV heave (pulmonary hypertension), a narrow pulse pressure or pulsus [patient.info]

Dilated Cardiomyopathy

Pulsus alternans is an infrequent, complex pathophysiologic sign often associated with severe heart failure. [ncbi.nlm.nih.gov]

Evaluation noted pulsus alternans, with beat-to-beat alternations in aortic pulse wave amplitude, both clinically and on diagnostic studies. [ncbi.nlm.nih.gov]

Recognition of pulsus alternans is important as it provides significant clinical information, may suggest suboptimal medical management, and may be the first warning sign [ncbi.nlm.nih.gov]

Heart Failure

Pulsus alternans is usually associated with an S 3 gallop, signifies advanced myocardial disease, and often disappears with treatment of heart failure. [emedicine.medscape.com]

Cardiomyopathy

Cardiomyopathy is a complicated disease of the heart muscle that compromises the muscle's "contractility" for efficiently delivering blood to the body. There are a number of possible causes, ranging from bacterial and viral infections to metabolic disorders, drugs and toxins, and connective tissue disorders,[…] [aopa.org]

Myocardial Infarction

Myocardial infarction Other names Acute myocardial infarction (AMI), heart attack A myocardial infarction occurs when an atherosclerotic plaque slowly builds up in the inner lining of a coronary artery and then suddenly ruptures, causing catastrophic thrombus formation, totally occluding the artery and preventing[…] [en.wikipedia.org]

Acute Myocardial Infarction

We herein report the case of a 25-year-old Japanese woman with left-main-trunk acute myocardial infarction (LMT-AMI). She had cardiogenic shock, so emergency percutaneous intervention was performed. Intravascular ultrasound of LMT-AMI showed that the three-layered structure of the intima, tunica media, and[…] [ncbi.nlm.nih.gov]

Acute Myocarditis

AIM: Cardiac magnetic resonance (CMR) can visualize inflammatory tissue changes in acute myocarditis. Several quantitative image-derived parameters have been described to enhance the diagnostic value of CMR, but no direct comparison of these techniques is available. METHODS AND RESULTS: A total of 34 patients with[…] [ncbi.nlm.nih.gov]

Primary Cardiomyopathy

PURPOSE OF REVIEW: Noncompaction of the left ventricle is a descriptive anatomical term and recently recognized primary cardiomyopathy. Cardiac imaging now allows for prompt detection. The specific etiology remains poorly understood, however, and the major genetic determinants are unknown. This review describes[…] [ncbi.nlm.nih.gov]

Toxic Myocarditis

We report the case of an 18-year-old woman with personality disorders who was hospitalized a few hours after suicidal ingestion of acetaminophen, quetiapine, acetylsalicylic acid, and ethanol. Twelve hours after admission, severe liver damage was evident, but the patient was stable and awaiting hepatic transplantation.[…] [ncbi.nlm.nih.gov]

Lymphocytic Myocarditis

OBJECTIVE: Although lymphocytic myocarditis (LM) clinically can mimic myocardial infarction (MI), they are regarded as distinct clinical entities. However, we observed a high prevalence (32%) of recent MI in patients diagnosed post-mortem with LM. To investigate if LM changes coronary atherosclerotic plaque, we[…] [ncbi.nlm.nih.gov]

Myocardial Fibrosis

BACKGROUND: Adverse fibrotic remodeling is detrimental to myocardial health and a reliable method for monitoring the development of fibrotic remodeling may be desirable during the follow-up of patients after heart transplantation (HTx). Quantification of diffuse myocardial fibrosis with cardiovascular magnetic[…] [ncbi.nlm.nih.gov]

Hypersensitivity Myocarditis

Eosinophilic myocarditis is an inflammatory condition of the heart in which the infiltrate is composed predominately of eosinophils. We identified three cases of eosinophilic myocarditis in which the infiltrating eosinophils showed a remarkable intimate association with bundles of collagen. Two of the hearts examined were[…] [ncbi.nlm.nih.gov]

Viral Myocarditis

AIMS: Viral myocarditis (VM) is an important cause of heart failure and sudden cardiac death in young healthy adults; it is also an aetiological precursor of dilated cardiomyopathy. We explored the role of the miR-221/-222 family that is up-regulated in VM. METHODS AND RESULTS: Here, we show that microRNA-221[…] [ncbi.nlm.nih.gov]

Bacterial Myocarditis

Bacterial myocarditis is an inflammatory condition of the heart, caused by a bacterial infection. It is an uncommon occurrence in the western world and is mostly diagnosed as a complication of sepsis or a specific syndrome involving a bacterial infection.
