Acute Atrial Infarction
Acute Atrial Heart Attack

Presentation

Patients with myxomas most frequently present with embolism, intracardiac obstruction, constitutional symptoms, and arrhythmia [3]. [ajronline.org]

Conversely, there are cases of left atrial myxoma presenting as acute MI but with normal coronary arteries. [hindawi.com]

We present a case report and review of the literature on this disease association. A 57-year-old woman was admitted to our coronary care unit with a diagnosis of non-ST elevation acute myocardial infarction. [elsevier.pt]

Case report An 80-year-old woman with a history of hypertension, dyslipidaemia and previously treated localised breast cancer, presented to a regional hospital with central chest heaviness. [tandfonline.com]

    Objective: To compare the incidence of predicted significant coronary lesions by DTS among various risk factors for coronary heart disease. [175.111.88.38]

    Myocardial Infarction The most frequent heart disease in western countries is coronary heart disease. Every second patient with coronary heart disease suffers acute myocardial infarction (12, 13). [coaguchek.com]

  • Chest Pain

    Rates for other chest pain presentations were not significantly increased ( figure 4 ). [journals.plos.org]

    Chest pain related to coronary ischemia without MI is known as angina. The chest pain of angina is typically of lesser severity and shorter duration than that of acute MI. [calshipleymd.com]

    Also, women are less likely to experience the classic symptoms of chest pain ; rather, they may feel a sense of fullness in their chest or pain in their arm, neck, back or jaw. [webmd.com]

    Because of the continuous chest pain associated with a rapid rate of AF, electrical cardioversion to sinus rhythm was carried out with 50 J monophasic synchronized cardioversion. [ncbi.nlm.nih.gov]

  • Retrosternal Chest Pain

    chest pain during sexual intercourse. [ajronline.org]

    A 53-year-old man with known diabetes mellitus and hypertension and no reported history of ischemic heart disease presented to the emergency department complaining of severe retrosternal chest pain. [ncbi.nlm.nih.gov]

  • Slow Pulse

    MIs involving the inferior (lower) wall of the left ventricle may result in abnormally slow pulse (bradycardia) and low blood pressure (hypotension). [calshipleymd.com]

  • Skipped Beats

    Rapid and irregular heart rates may be perceived as the sensation of the heart beating too fast, irregularly, or skipping beats (palpitations) or exercise intolerance and occasionally may produce anginal chest pain (if the high heart rate causes the heart's [en.wikipedia.org]

Workup

The patient's hypercoagulation workup returned with antithrombin III of 89, total protein S of 98, free protein S of 60, and protein C of 110, and was negative for both lupus anticoagulant and a prothrombin gene mutation. [n.neurology.org]

The results of the diagnostic workup included: 1) chest X-ray: an enlarged left ventricle (LV) and a bilateral alveolar infiltrate in pulmonary bases; 2) electrocardiogram (ECG): atrial fibrillation, necrosis and ST segment elevation in the lateral wall [scielo.br]

The stroke unit handles all stages of acute care, workup, and all stages of rehabilitation in all patients, regardless of the age of the patient, the severity of the stroke, and the condition of the patient prior to the stroke. [ahajournals.org]

  • Premature Atrial Contractions

    Arrhythmias are quite common in the setting of atrial infarctions and include paroxysmal AF, wandering atrial pacemaker, premature atrial contractions and runs of atrial tachycardia (9). [ncbi.nlm.nih.gov]

    In previous studies, echocardiographic left atrial diameter (LAD) and premature atrial contractions on Holter monitoring were the predictors of PAF in patients with acute ischemic stroke [4, 5]. [medsci.org]

T Wave

  • Biphasic T Wave

    The other normal variant that may be associated with prominent T wave inversion is the early repolarization pattern. Some subjects with this variant have prominent, biphasic T wave inversion in association with the ST elevation. [angelfire.com]

After a risk/benefit analysis, we started treatment with anticoagulants 3 days after admission; this treatment was continued for 15 days, until surgical resection of the left atrial mass was possible. [elsevier.es]

Once diagnosed, treatment approach should be decided to restore intestinal perfusion as quickly as possible [ 10 ]. [e-jnc.org]

Prognosis

However, the long-term prognosis is still unknown. We aimed to assess 1-year prognosis in patients experiencing silent AF in AMI. [heart.bmj.com]

Outcome was assessed by modified Rankin Scale (mRS) which was obtained 180 days after stroke by telephone interview (mRS ≤ 2 reflected good prognosis, and mRS>2 reflected unfavorable prognosis), and death defined as all-cause mortality. [ncbi.nlm.nih.gov]

Etiology

Conclusion: Of the many etiologies that cause bradycardia, there is the most dangerous etiology. Two different rhythms are AV degree II and AV block III (total AV block). [bikinflipchart.wordpress.com]

The imaging techniques described above can demonstrate the presence of an area of decreased perfusion but not the etiology of the infarction. The specific etiology is apparent from the history, physical examination, and laboratory investigations. [journals.lww.com]

Its etiology may include left ventricular dysfunction with hemodynamic disturbances [1–6], pericarditis [7], metabolic abnormalities, excess catecholamine release or iatrogenic factors (e.g., use of sympathomimetic drugs) [8]. [onlinejacc.org]

A comprehensive report was published by Lazar et al1, with an excellent review of the history, incidence, anatomy, pathology and etiological, clinical and diagnostic aspects of acute atrial infarction. [scielo.br]

They may account for up to 20% of acute strokes and have been reported to have the highest 1-month mortality. [6] (See Pathophysiology.) [emedicine.medscape.com]

Prevention

In the ENGAGE AF-TIMI 48 trial (n=21,105), edoxaban was noninferior to warfarin with respect to the prevention of stroke or systemic embolism. [emedicine.medscape.com]

This is done, in part, by administering beta blockers to prevent damage caused by the excessive production of adrenaline and high-dose statins to stabilize ruptured plaque and reduce arterial inflammation. [verywell.com]

And in some of these persons, strokes have been found which were then treated with thrombolytic medication.[65] Prevention Given the disease burden of strokes, prevention is an important public health concern.[67] Primary prevention is less effective [en.wikipedia.org]

Effective medications are available to prevent the spread of thrombosis and the consecutive occurrence of potentially fatal pulmonary embolism. [coaguchek.com]
