    SummaryA 49-year-old woman was referred to our hospital for uncontrollable heart failure. She had never been diagnosed as having sarcoidosis. Chest X-ray showed cardiomegaly without bilateral hilar lymphadenopathy. Echocardiography showed diffuse hypokinesis of the left ventricle mimicking idiopathic dilated cardiomyopathy. No specific manifestations implying sarcoidosis were observed. On cardiac catheterization, coronary angiograms were normal, whereas concurrent routine endomyocardial biopsy showed foci of non-caseating granuloma, indicating sarcoidosis. Pathological finding was the only clue to diagnose cardiac sarcoidosis among our standard examinations for heart failure. No other additional investigations found any extracardiac features of sarcoidosis. All serological and immunological examinations were within normal range. This is a challenging case of biopsy-proven cardiac sarcoidosis without any other extracardiac involvement

    Stent Graft for Rapidly Growing Thoracic Mycotic Aneurysm in a Patient with Advanced Lung Cancer

    We report a compromised patient with mycotic aneurysm, who was successfully treated by urgent placement of a stent graft. A man in his seventies was admitted to our hospital with relapsing high fever and back pain during chemotherapy for advanced squamous cell carcinoma of the lung. Contrast CT demonstrated a saccular aneurysm of the thoracic aorta and left pleural effusion. Blood cultures were positive for Escherichia coli producing extended spectrum beta-lactamase (ESBL). Therefore, thoracic mycotic aneurysm was diagnosed. Because of rapid growth on consecutive examinations, absolute bed rest was required. Therefore, we performed antibiotic therapy combined with stent graft placement, which achieved complete exclusion of the aneurysm. He was discharged in an ambulatory state, and his quality of life remained good at home until just before death from terminal state of the cancer

    BACKGROUND The selective cardiac myosin activator omecamtiv mecarbil has been shown to improve cardiac function in patients with heart failure with a reduced ejection fraction. Its effect on cardiovascular outcomes is unknown. METHODS We randomly assigned 8256 patients (inpatients and outpatients) with symptomatic chronic heart failure and an ejection fraction of 35% or less to receive omecamtiv mecarbil (using pharmacokinetic-guided doses of 25 mg, 37.5 mg, or 50 mg twice daily) or placebo, in addition to standard heart-failure therapy. The primary outcome was a composite of a first heart-failure event (hospitalization or urgent visit for heart failure) or death from cardiovascular causes. RESULTS During a median of 21.8 months, a primary-outcome event occurred in 1523 of 4120 patients (37.0%) in the omecamtiv mecarbil group and in 1607 of 4112 patients (39.1%) in the placebo group (hazard ratio, 0.92; 95% confidence interval [CI], 0.86 to 0.99; P = 0.03). A total of 808 patients (19.6%) and 798 patients (19.4%), respectively, died from cardiovascular causes (hazard ratio, 1.01; 95% CI, 0.92 to 1.11). There was no significant difference between groups in the change from baseline on the Kansas City Cardiomyopathy Questionnaire total symptom score. At week 24, the change from baseline for the median N-terminal pro-B-type natriuretic peptide level was 10% lower in the omecamtiv mecarbil group than in the placebo group; the median cardiac troponin I level was 4 ng per liter higher. The frequency of cardiac ischemic and ventricular arrhythmia events was similar in the two groups. CONCLUSIONS Among patients with heart failure and a reduced ejection, those who received omecamtiv mecarbil had a lower incidence of a composite of a heart-failure event or death from cardiovascular causes than those who received placebo.
