24 LV thrombus is common in PPCM patients, and some patients presenting with peripheral embolic episodes including cerebral and coronary embolism have been described in the literature.25, 26 The diagnosis of PPCM involves a high index of Dasatinib manufacturer suspicion as symptoms may be similar to those of physiological changes that occur during pregnancy. It also is a diagnosis of exclusion, and a thorough investigation must be done to rule out an alternative etiology of heart failure.22 Initial investigation usually involves routine blood tests to rule out anemia, electrolyte disturbances, and liver, renal, and thyroid

Electrocardiogram (EKG) findings may be Inhibitors,research,lifescience,medical nonspecific. Sinus tachycardia, atrial fibrillation, atrial flutter, and ventricular tachycardia have been reported in patients with PPCM. An EKG QRS time of ≥120 ms has been identified as a predictor for mortality, indicating a potential impact of QRS time on the mortality of patients with PPCM.27 Echocardiogram is used to rule out other causes of heart failure such as valve disease and to establish reduced ejection fraction.

Among patients with LVEF >30% at diagnosis, restoration of normal LVEF is more likely. The left ventricle may not always be dilated; however, an initial left ventricular end-systolic Inhibitors,research,lifescience,medical diameter of ≤5.5 cm has been shown to predict recovery of left ventricle function.27 LV thrombus has been found on initial echocardiography in 10–17% of patients.28,29 PPCM also is associated with an increased incidence of thromboembolism compared with DCM from other etiologies. Other imaging modalities such as cardiac MRI do not show any specific pattern

One of the study’s objectives is to investigate the frequency of myocardial injury or inflammation on cardiac MRI and the ability of tissue characteristics to predict subsequent recovery of LVEF.31 Endomyocardial Astemizole biopsy is not routinely recommended or a part of the typical diagnostic work up of PPCM. If a biopsy seems warranted based on suspicion of other infiltrative cardiomyopathies or treatable causes, it should be undertaken with caution. A variable proportion of patients with PPCM may have evidence of myocarditis, and since there are no pathognomonic findings in PPCM, there is an inherent risk in performing a biopsy of a dilated right ventricle. Management A multidisciplinary approach involving a cardiologist, obstetrician, intensivist, anesthesiologist, and pediatrician is essential and should be engaged as early as possible.
