This case of CPF is unusual with respect to the site of origin showing multiple involvement including the papillary muscle (its prevalence

in the literature is only about 1% in CPF) and the large amount of thrombus in the left atrium.
A reversible form of dilated cardiomyopathy (DCM) can be developed from alcohol drinking, pregnancy, chronic uncontrolled tachycardia, hypothyroidism, hyperthyroidism, drug use and other endocrine dysfunctions.1),2) Thyroid hormone has a great effect on the heart and vascular system.1) The heart is sensitive to changes in thyroid hormones, and Inhibitors,research,lifescience,medical cardiac disorders are commonly associated with both hyper- and hypothyroidism.3),4) Hemodynamic changes caused by hyperthyroidism lead to classic Gemcitabine synthesis hyperdymamic cardiovascular state, and they are associated with increase in cardiac output and reduction in peripheral Inhibitors,research,lifescience,medical vascular resistance.5) On the other hand, hypothyroidism is associated with bradycardia, mild diastolic hypertension, narrow pulse pressure and slightly increased mean arterial pressure.6) According to a review of literatures, diastolic dysfunction is the most common finding seen in patients

with hypothyroidism.7) In addition, it is commonly encountered that the left ventricular systolic function is minimally decreased with slightly reduced ejection fraction Inhibitors,research,lifescience,medical and stroke volume.8) DCM is a rare presentation of hypothyroidism.9) We experienced a case of a 36-year-old man with DCM accompanied by undiagnosed primary hypothyroidism. Here, we report our case with a review of literatures. Case A 36-year-old man presented to the emergency room with dyspnea of New York Heart Association Inhibitors,research,lifescience,medical functional class III/IV and fatigue. The patient had a 1-year-history of chief complaints of weakness of all four extremities, weight gain and bilateral lower extremity edema. For two Inhibitors,research,lifescience,medical months prior to most admission, the patient had a progressive worsening of bilateral lower extremity edema. On physical

examination, the patient had body mass index (BMI) 28.6 kg/m2 and vital signs such as blood pressure 130/90 mmHg, pulse rate 90 beats/min, respiratory rate 20 breaths/min and O2 saturation 96% in room Carfilzomib air. In addition, the patient had pale and dry skin. Heart rate was regular and systolic murmur was heard at the apex. Breath sounds were decreased with inspiratory crackles on bilateral lung bases. The patient also had bilateral presence of non-pitting edema of the foot and ankle. On chest X-ray, the patient had cardiomegaly with perihilar congestion and blunting of both costophrenic angles. These findings are suggestive of pleural effusion (Fig. 1). On electrocardiographic findings, the patient had normal sinus rhythm with low voltage of limb leads, interventricular conduction delay and non-specific ST-segment and T-wave changes (Fig. 2).
