Acromegaly is associated with an enhanced mortality, with cardiovascular and respiratory complications representing not only the most frequent comorbidities but also two of the main causes of deaths, whereas a minor role is played by metabolic complications, and particularly diabetes mellitus. The most prevalent cardiovascular complications of acromegaly include a cardiomyopathy, characterized by cardiac hypertrophy and diastolic and systolic dysfunction together with arterial hypertension, cardiac rhythm disorders and valve diseases, as well as vascular endothelial dysfunction...

OBJECTIVE: Patients with end-stage renal disease have multiple comorbidities and are at increased risk for postoperative complications and resource utilization. Our goal was to determine the rate and causes of 30-day and 90-day hospital readmissions after the creation of outpatient hemodialysis access. METHODS: We retrospectively reviewed all outpatient upper extremity hemodialysis access creations performed at our medical center from 2008 to 2015. Readmission was defined as any inpatient status admission ≤30 and 90 days...

A 22-year-old woman presented to the emergency department (ED) with a 24-hour history of nausea, vomiting, diarrhea, generalized abdominal pain, and mild headache. She denied shortness of breath, chest pain, or anxiety, and didn't have a history of cardiac problems. The physical examination revealed tachycardia (heart rate, 135 beats/min) and a respiratory rate of 24 breaths per minute.

A 36-year-old woman was seen with complaints of exertional chest pain and shortness of breath. Her medical history included atrial fibrillation and diabetes. Physical examination was unremarkable except for an irregular cardiac rhythm. Myocardial perfusion imaging revealed the presence of a large area of infarction involving the entire anterior and apical walls and part of the anteroseptal wall with minimal periinfarct ischemia. Computed tomography coronary angiogram revealed an anomalous left main coronary artery arising from the main pulmonary artery...

Hypersensitivity myocarditis is a rare but serious adverse effect of clozapine, a commonly used psychiatric drug. We report the case of sudden cardiac death from clozapine-induced hypersensitivity myocarditis diagnosed at autopsy. A 54-year-old Caucasian male on clozapine therapy for bipolar disorder presented with a sudden onset of shortness of breath. Laboratory studies were significant for elevated N-terminal prohormone of brain natriuretic peptide. During his hospital stay, the patient died of sudden cardiac arrest from ventricular tachycardia...

The recent SERVE HF study concluded that patients with chronic heart failure (CHF) and Cheyne-Stokes respiration (CSR) have increased mortality when treated with adaptive servo-ventilation (ASV). We, therefore, wanted to explore if these patients tolerated discontinuation of ASV treatment. The study was a prospective post-ASV treatment observational design with a 3-month follow-up period. 14 patients from our outpatient clinic, all male, were originally diagnosed with CHF and Cheyne-Stokes respiration, which is a clinical form of central sleep apnea...

BACKGROUND: Use of medications containing the 5-aminosalicylic acid (5-ASA) moiety may cause a rare but potentially lethal side effect involving inflammation of the heart (myocarditis) or pericardium (pericarditis) or both (myopericarditis). Early recognition of 5-ASA as the cause is important to prevent progression of the inflammation. OBJECTIVE: To provide clinicians with information to assist in recognizing the signs and symptoms of 5-ASA-induced cardiac inflammation and the characteristics of the suspected therapy, and in determining the appropriate approach to treatment...

BACKGROUND: Cardiac lipomas are rare benign tumors of the heart. They are usually asymptomatic and are thus most often diagnosed on autopsies. Symptoms, when present, depend upon the location within the heart. Typical locations are the endocardium of the right atrium and the left ventricle. Diagnostic modality of choice is cardiac MRI. Treatment guidelines have not yet been established due to the very low prevalence of these tumors and are thus guided by the patient's symptomatology. CASE PRESENTATION: We describe a case of an invasive cardiac lipoma, wherein the initial symptom of the patient was shortness of breath...

INTRODUCTION: Myocardial perfusion imaging (MPI) is widely used in the evaluation of known and suspected coronary artery disease (CAD). Imaging of heart in stress and rest enables the comparison of myocardial uptake of radiotracer in proportion to the needs and coronary flow, which is used for detection of perfusion defects. Exercise stress and pharmacologic agents are used for the stressing purpose. Novel pharmacologic stressor regadenoson is A2A selective adenosine agonist, which selectively binds to the adenosine receptors in coronary arteries causing coronary dilatation...

BACKGROUND: Segmented cine imaging with a steady-state free-precession sequence (Cine-SSFP) is currently the gold standard technique for measuring ventricular volumes and mass, but due to multi breath-hold (BH) requirements, it is prone to misalignment of consecutive slices, time consuming and dependent on respiratory capacity. Real-time cine avoids those limitations, but poor spatial and temporal resolution of conventional sequences has prevented its routine application. We sought to examine the accuracy and feasibility of a newly developed real-time sequence with aggressive under-sampling of k-space using sparse sampling and iterative reconstruction (Cine-RT)...

BACKGROUND: The clinical features of bacteria endocarditis became atypical when consolidated with other conditions such as tuberculosis (TB). Especially, the symptoms of bacteria endocarditis (BE) which were hidden behind the TB fever often lead to misdiagnosis and missed diagnosis. CASE PRESENTATION: A 56-year-old male with thoracic vertebra bone TB history presented with low-grade fever, shortness of breath and cardiac souffle. After conventional antibiotic therapy and strengthen anti-tuberculosis treatment condition did not be improved...

BACKGROUND: Primary cardiac angiosarcomas are rare, but they are the most aggressive type of primary cardiac neoplasms. When patients do present, it is with advanced pulmonary and/or cardiac symptoms. Therefore, many times the correct diagnosis is not made at the time of initial presentation. These patients have metastatic disease and the vast majority of these patients die within a few months after diagnosis. Currently the treatment choices are limited and there are no targeted therapies available...

PURPOSE: Unlike echocardiography which can quantify both LV filling and ejection, cine steady state free precession sequence (SSFP)-despite its high intrinsic signal and contrast to noise ratio, accuracy and precision of volume measurements-, is mostly relegated to quantifying LV ejection. The steady-state requirement typically constrains SSFP sequence to a breathhold (and limited temporal resolution). We describe: (a) free breathing cine SSFP approach that meets the SS requirement allowing high frame rate acquisition, (b) two MRI indices based on time-LV volume (TV) change during filling and compare against echocardiagraphic diastolic index (E/A ratio), and (c) evaluate the effect of temporal resolution on: LV volumes; ejection and filling rates; and normalized indices of systolic and diastolic function...

Clozapine-related pericarditis is a rare side effect of the drug. We reported the clinical cases of two women, aged 22 and 28 years, affected by schizophrenia with pericarditis symptoms related to clozapine treatment of 200 mg/day. Clozapine was discontinued in both patients, resulting in normalization of the ECG changes, and echocardiography confirmed the progressive disappearance of the pericardial effusion. Interestingly, while inflammatory indices and pro-brain natriuretic peptide (pro-BNP) plasma levels were high in both patients, only one of them showed tachycardia, subjective chest pain, shortness of breath and dyspnea, with a clinical symptomatology suggesting a cardiac involvement...

Delayed cardiac tamponade (DCT) is a rare and life-threatening complication of catheter ablation performed as a treatment of atrial fibrillation, with few cases described in the medical literature. We present the case of a 57year-old man presenting with DCT 61days following a catheter ablation procedure. To the best of our knowledge, this is the most delayed case of cardiac tamponade (CT) following catheter ablation described in the literature. We also discuss the importance of point of care ultrasound (POCUS) in the diagnosis and treatment of CT...

A 78-year-old man was admitted to the authors' hospital with a short history of shortness of breath and pyrexia. He had long-standing moderate mitral regurgitation and stable coronary artery disease. Blood cultures grew Abiotrophia defectiva coccobaccili. Transesophageal echocardiography confirmed the diagnosis of mitral valve endocarditis that necessitated treatment with intravenous benzylpenicillin and gentamicin for six weeks. At nine days after admission the patient developed several episodes of self-limiting monomorphic ventricular tachycardia, without ischemic cardiac pain, associated with hemodynamic compromise requiring treatment with intravenous amiodarone and inotropic support in the Intensive Care Unit...

INTRODUCTION: Troponins are known to be released in response to cardiac damage and therefore are the biomarkers of choice for the early diagnosis of acute myocardial infarction (AMI), improving outcome in patients presenting with chest pain. However, false results can occur due to interference from other substances in the blood. CASE: A 52-year-old male with a past medical history of alcohol abuse, hypertension, and coronary artery bypass graft at age 34 with normal stress test 2 years before presented to the emergency department (ED) complaining of 1 day of non-exertional chest pain with radiation to the neck and left arm...
