Safety and efficacy of oxycodone for refractory dyspnea in end-stage heart failure patients with chronic kidney disease: a case series of eight patients.

Background: Morphine is effective in palliative care for patients with end-stage heart failure; however, its use is avoided in patients with impaired renal function because it tends to induce adverse effects. Although oxycodone has been reported to be a useful alternative, the evidence is insufficient. Therefore, we investigated the safety and efficacy of oxycodone in eight patients with end-stage heart failure complicated by chronic kidney disease.

Hematobium schistosomiasis control for health management of labor force generation at Nkhotakota and Lilongwe in the Republic of Malawi-assumed to be related to occupational risk.

Background: In Malawi, hematobium schistosomiasis is highly endemic. According to previous studies, countermeasures have been conducted mainly in school-aged children. In this study, we focused on the age groups, which are assumed to be major labor force generation.

IgA Vasculitis with Simultaneous Cardiopulmonary Involvement.

A 60-year-old man with a history of hypertension, type 2 diabetes, and reflux esophagitis was admitted to our hospital with hemoptysis, dyspnea, and leg edema. We diagnosed him with adult IgA vasculitis based on the presence of purpura, elevated serum IgA fibronectin complexes, pathophysiological findings, a skin biopsy showing leukocytoclastic vasculitis, and immunofluorescence studies demonstrating granular IgA and C3 deposits in the blood vessel wall. He showed concurrent cardiopulmonary involvement without involvement of the gastrointestinal system and kidneys, which are commonly affected in IgA vasculitis patients.

Efficacy of Oxycodone for Dyspnea in End-stage Heart Failure with Renal Insufficiency.

A 67-year-old man with dilated cardiomyopathy and renal insufficiency was admitted to our hospital with dyspnea secondary to end-stage heart failure. We introduced oxycodone for medically refractory dyspnea instead of morphine because of the patient's renal insufficiency. After the administration of oxycodone, his dyspnea was alleviated without any adverse opioid effects, such as respiratory depression.

Nicorandil was an Effective Treatment Option for a Patient with Bland-White-Garland Syndrome.

A 75-year-old woman who had previously been diagnosed with Bland-White-Garland syndrome was admitted to our hospital for acute decompensated heart failure (ADHF). Following her recovery from ADHF, pharmacologic stress myocardial scintigraphy revealed myocardial ischemia in the basal anterior area of the left ventricle. Moreover, myocardial scintigraphy showed the improvement of the myocardial ischemia after 6 months of nicorandil administration.

Thrombectomy and Catheter-Directed Thrombolysis Combined With Antithrombin Concentrate for Treatment of Antithrombin Deficiency Complicated by Acute Deep Vein Thrombosis That Is Refractory to Anticoagulation.

A 22-year-old male was admitted to our hospital with deep vein thrombosis that was complicated by antithrombin deficiency. This deficiency was refractory to anticoagulation therapy. Although catheter-directed thrombolysis could not reperfuse the total occlusion in the left deep vein, a combination of thrombectomy, catheter-directed thrombolysis, and antithrombin concentrate treatment was able to dissolve the clots and ameliorate the blood flow into the left deep vein.

[A Case of Heparin-Induced Thrombocytopenia with Discrepancy in the Results of Anti-Platelet Factor 4/Heparin Antibodies between Latex-Particle-Enhanced Immunoturbidimetric Assay and Enzyme Immunoassay].

A female patient in her seventies with diabetes mellitus, hyper-lipidemia and mitral regurgitation was admitted because of the acute heart failure. She was treated with diuretics and vasodilators, however these were not effective. Therefore the CHDF using heparin was required for the patients.

[Recent trends in the clinical characteristics of infective endocarditis: a survey of 54 consecutive cases from 2006 to 2010].

Background: It has been reported that the clinical characteristics of infective endocarditis are changing during the course of the decades. However, most of the available data are obtained in the early 2000s or earlier. We therefore evaluated the more recent clinical spectrum of infective endocarditis.

Effect of eicosapentaenoic acid on regional arterial stiffness: Assessment by tissue Doppler imaging.

Aim: To evaluate the effects of eicosapentaenoic acid (EPA) on regional arterial stiffness assessed by strain rate using tissue Doppler imaging.

Methods: Nineteen eligible patients were prospectively studied (mean age 62 ± 8 years, 68% men). Subjects with large vessel complications and/or diabetes mellitus were excluded.

Prognostic value of normal stress-only technetium-99m myocardial perfusion imaging protocol. Comparison with standard stress-rest protocol.

Background:  Patients with a normal stress image on technetium-99m (Tc-99m) single-photon emission computed tomography (SPECT) have a good prognosis for diagnosing coronary artery disease. However, current guidelines recommend stress and rest imaging to confirm that a stress image is normal.

Methods And Results:  We determined all-cause of cardiac events (acute coronary syndrome and sudden death) in 1,939 patients undergoing stress myocardial perfusion SPECT with Tc-99m radiotracers.

Pseudoaneurysm with left-to-right shunt in a patient with myocardial infarction: evaluation by three-dimensional echocardiography.

It is often difficult to noninvasively differentiate a post-infarction left ventricular (LV) pseudoaneurysm from a post-infarction true aneurysm. A 66-year-old woman with a past history of inferior acute myocardial infarction was admitted to our hospital because of acute decompensated heart failure. Two-dimensional transthoracic echocardiography showed an aneurysm with a narrow orifice in the inferoposterior basal area.

Obesity as an independent risk for left ventricular diastolic dysfunction in 692 Japanese patients.

Background: Both obesity and left ventricular (LV) diastolic dysfunction are associated with an increased risk of cardiovascular morbidity and mortality. There is a paucity of data as to whether obesity is independently associated with LV diastolic dysfunction.

Methods: Adult patients with sinus rhythm referred for a transthoracic echocardiography between July, 2007, and December, 2007, were prospectively included.

Atypical morphology and myocardial perfusion of mid-ventricular ballooning: A case report.

Although some atypical types of transient left ventricular apical ballooning syndrome have been reported, only a few atypical types of transient mid-ventricular ballooning have been reported. A 70-year-old female underwent surgery for urothelial carcinoma. At day 5 after the surgery, she was admitted to our department without cardiac symptoms because of ST elevation in leads I, II, III, aVF and V1-V6 indicating acute coronary syndrome.

Left ventricular apical ballooning syndrome in a patient with infundibular stenosis of the right ventricle: A case report.

A 73-year-old female patient with a past history of right ventricular infundibular stenosis was admitted to our intensive care unit because of right ventricular dysfunction. On the fifth day of hospitalization, she suddenly experienced dyspnea without chest pain despite the improvement of her condition by initial medical treatment. Although electrocardiography revealed no ST-segment elevation, echocardiography and myocardial perfusion using Tc-MIBI revealed new development of severe symmetrical akinesia and reduced perfusion of the left ventricular (LV) apex and mid-ventricle.

Direct correlation between regional systolic function and regional washout rate of ⁹⁹mTc-sestamibi in patients with idiopathic dilated cardiomyopathy.

Objective: Although a higher washout of ⁹⁹mTc-sestamibi (MIBI) from the ischemic myocardium was reported, little is known about it in idiopathic, nonischemic dilated cardiomyopathy (DCM). Using a quantitative electrocardiographic-gated single-photon emission computed tomography strategy, regional myocardial function may be obtained in conjunction with regional tracer perfusion. The aim of this study was to investigate the significance of regional washout of MIBI compared with regional systolic function in patients with DCM.

Left atrial volume by real-time three-dimensional echocardiography: validation by 64-slice multidetector computed tomography.

Background: Left atrial (LA) enlargement has been acknowledged as a significant predictor of cardiovascular morbidity and mortality.

Methods: To evaluate the accuracy of two-dimensional and three-dimensional echocardiography for determining LA volume, LA volume measurements by echocardiography were compared with those measured by 64-slice multidetector computed tomography (MDCT) as a reference standard.

Results: Fifty-seven consecutive patients (mean age, 66 ± 11 years; 59% men) referred to echocardiography and MDCT on the same day were prospectively evaluated.

Clinical significance of ischemic electrocardiographic changes during stress myocardial perfusion imaging: sub-analysis of the J-ACCESS study.

Objectives: The cardiac event rate among the countries varies according to ethnicity. Some reports have identified that ischemic heart disease often occurs at a low incidence and is often milder in Japan compared to other countries. Therefore, the present study was designed to determine the clinical significance and prediction for cardiac events in patients who showed ischemic ECG changes during stress myocardial perfusion SPECT.

Factors associated with myocardial salvage immediately after emergent percutaneous coronary intervention in patients with ST-elevation acute myocardial infarction.

Objective: The amount of myocardial salvage after percutaneous coronary intervention (PCI) is reported to be a major determinant of functional recovery in patients with ST-elevation acute myocardial infarction (MI). However, factors related to the amount of myocardial salvage remain unknown. The goal of this study was to investigate the factors related to the amount of myocardial salvage after emergent PCI in patients with ST-elevation acute MI by incorporating pre- and post-treatment indices and adjunctive treatments.

Non-invasive detection of ischemic left ventricular dysfunction using rest gated SPECT: expectation of simultaneous evaluation of both myocardial perfusion and wall motion abnormality.

Objective: Although the accurate detection of ischemic etiology is important in the management of patients with severe left ventricular (LV) dysfunction, it is difficult to determine using a non-invasive strategy. The present study investigates whether perfusion and regional functional abnormalities identified by quantitative electrocardiographic gated single-photon emission computed tomography (QGS) at rest can detect ischemic LV dysfunction in patients with severe LV dysfunction.

Methods: Rest QGS with (99m)Tc-tetrofosmin was performed on 54 consecutive patients with LV ejection fraction of View Article and Find Full Text PDF

Different time course of changes in tricuspid regurgitant pressure gradient and pulmonary artery flow acceleration after pulmonary thromboendarterectomy: implications for discordant recovery of pulmonary artery pressure and compliance.

Background: Pulmonary artery pressure (PAP) is reduced dramatically after pulmonary thromboendarterectomy in patients with chronic thromboembolic pulmonary hypertension (CTEPH). However, it is unclear whether pulmonary artery compliance increases in conjunction with the reduction in PAP. Pulmonary artery compliance may affect right ventricular afterload and prognosis.

'Takotsubo' cardiomyopathy in a maintenance hemodialysis patient.

An 84-year-old woman undergoing maintenance hemodialysis presented with chest discomfort lasting several days and electrocardiographic abnormalities. She had stopped smoking 2 weeks earlier and was experiencing irritability. Upon admission, electrocardiography showed ST-segment elevation in leads I, II, aVF, and V2-6 and an abnormal Q wave in leads II, III, and aVF.

Effect of beta-blockers on the mortality of Japanese patients with myocardial infarction.

Background: After a myocardial infarction, a higher prevalence of coronary vasospastic response has been reported in the Japanese population than in the Caucasian population. Beta-blockers may exacerbate coronary vasospasm. However, beta-blockers are given to Japanese patients after an acute myocardial infarction, though the mortality benefit is unknown.
