Recovery of Endothelial Function After Sirolimus-Eluting Stent Implantation: A Pilot Study
Whether endothelial dysfunction after sirolimus-eluting stent (SES) implantation is persistent has not been fully evaluated. Endothelial function was evaluated in 152 lesions that underwent follow-up coronary angiography after SES implantation. Lesions were classified into 2 groups according to the duration between SES implantation and follow-up: ≤12 months (n = 95) and >12 months (n = 57). Changes in coronary diameter in response to 10–8 mol/L (–2.4% ± 6.3% vs –4.9% ± 3.8%, P < .01) and 10–7 mol/L acetylcholine (Ach; –4.6% ± 7.6% vs –10.7% ± 9.1%, P ...

Prevalence of Noncalcified Coronary Plaque in Patients With Calcium Score of 0: The Silent Enemy
Noncalcified coronary artery plaques (NCAPs) are susceptible to rupture, resulting in coronary artery thrombosis. Using computer tomography coronary angiography (CTCA), we evaluated the prevalence and degree of stenosis caused by NCAP in patients without coronary artery calcification (CAC). A retrospective analysis of 447 symptomatic patients with 0 CAC score revealed negative CTCA in 400 (89.5%). Noncalcified coronary artery plaques were demonstrated in 47 (10.5%), with 4 presenting stenosis >50%. Patients with positive CTCA, compared to those with normal CTCA, had significantly higher mean age (56.2 years vs 50.6 year...

Clinical Presentation and Cardiovascular Risk Profiles in Patients With Left Main Coronary Artery Disease in a Middle Eastern Country
We evaluated the prevalence and clinical profile of patients with left main coronary artery disease (LMCA) in Qatar between 2006 and 2010. Patients were divided into 2 groups: patients with LMCA and patients without LMCA but had severe 3-vessel disease (VeD) eligible for surgical revascularization. Among 7000 patients who underwent coronary angiography, 210 patients had significant LMCA and 200 patients with severe 3VeD were matched for age and sex. Diabetes mellitus and hypertension were comparable in the 2 groups. Presentations with myocardial infarction or heart failure were comparable in both groups. Isolated LMCA was ...

Risk Score for the Prediction of Contrast-Induced Nephropathy in Elderly Patients Undergoing Percutaneous Coronary Intervention
We developed a risk score for contrast-induced nephropathy (CIN) in elderly patients (n = 668) before percutaneous coronary intervention (PCI). Another 277 elderly patients were studied for validation. Based on the odds ratio, risk factors were assigned a weighted integer; the sum of the integers was the risk score. Among the 668 elderly patients, 105 (15.7%) experienced CIN. There were 9 risk factors for CIN (with weighted integer): estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 (4), diabetes (3), left ventricular ejection fraction <45% (3), hypotension (2), age >70 years (2), myocardial infarctio...

Renalase, Hypertension, and Kidney -- The Discussion Continues
Hypertension and cardiovascular complications are very common in chronic kidney disease (CKD). Overactivation of sympathetic nervous system is also widely recognized in CKD. Renalase may play an important role in the control of blood pressure (BP) by its regulatory function of catecholamine metabolism. Renalase could be synthesized not only by the kidney but also by cardiomyocytes, liver, and adipose tissue. It probably exerts a hypotensive action, at least in animal models. Whether it metabolizes catecholamines remains to be proved. Another issue that remains to be resolved is the relationship between renalase and renal n...

Association Between Epicardial Fat Thickness and Weight Homeostasis Hormones in Patients With Noncachectic Heart Failure
The relationship between echocardiographically measured epicardial fat thickness (EFT) and plasma concentrations of leptin, ghrelin, and adiponectin has not been evaluated in patients with noncachectic heart failure (HF). Patients with noncachectic HF and age- and sex-matched controls did not differ significantly in EFT, whereas EFT values showed significant positive correlation with body mass index (BMI) in both groups and were negatively related with brain natriuretic peptide and positively with log leptin values in the HF group. In the control group, a positive correlation with high-sensitivity C-reactive protein (hsCRP...

Developing process guidelines for trauma care in the Netherlands for severely injured patients: results from a Delphi study
Conclusions: In this Delphi study, a large expert panel agreed on a set of guidelines describing the optimal process of care for severely injured trauma patients in the Netherlands. In addition to time intervals and appropriate actions, these guidelines emphasise the importance of team competence and interdisciplinary processes in trauma care. The guidelines can be seen as a description of a best practice and a new field standard in the Netherlands. The next step is to implement the guidelines and monitor the performance of the Dutch trauma system based on the guidelines.

Impaired cardioprotective function of transplantation of mesenchymal stem cells from patients with diabetes mellitus to rats with experimentally induced myocardial infarction
Conclusions: hMSCs from patients with CAD+DM and CAD alone both have proliferative properties. Transplantation of hMSCs ameliorate heart function, but proliferative ability and myocardial protection decrease significantly in MSCs obtained from patients with CAD+DM compared with cultures from patients with CAD alone, possibly as a result of differences in Bcl-2 protein expression and reduced anti-apoptosis.

Emergency cholecystectomy and hepatic arterial repair in a patient presenting with haemobilia and massive gastrointestinal haemorrhage due to a spontaneous cystic artery gallbladder fistula masquerading as a pseudoaneurysm
Conclusion: Fistula between the cystic artery and gallbladder has been commonly reported to occur after laparoscopic cholecystectomy. Spontaneous fistulous communication, i.e. in the absence of any prior trauma or intervention, between cystic artery and gallbladder is rare with very few reports in literature. Aetiopathogenesis of the disease, in the context of current literature is reviewed. The diagnostic dilemma posed by the confounding finding of an ulcer in the duodenum, the iconic video angiographic depiction as also the therapeutic challenge of a failed embolization with consequent microcoil migration and primary hep...

Takotsubo Cardiomyopathy: Overrepresentation of Cases
I read the report “Demographic and Co-Morbid Predictors of Stress (Takotsubo) Cardiomyopathy.” The investigators stated that 24,701 cases of stress cardiomyopathy were identified from the 2008 and 2009 Nationwide Inpatient Sample databases using International Classification of Diseases, Ninth Revision, Clinical Modification code of 42983. This number of cases appears too large, considering the rarity of the condition. It probably included admissions for acute myocardial infarction, considering that the 2 conditions have very similar clinical presentations. Although the correct International Classification of Diseases, ...

Usefulness of Frequent Electrocardiographic, Echocardiographic, and Serum Catecholamine Levels in Takotsubo Syndrome
The objective of this note is to gain the attention of clinicians who are destined to manage patients presenting with suspected TTS. Although the diagnosis of TTS is eventually made after a few hours to days of ambivalence in its differentiation from acute coronary syndromes (ACSs), we miss the opportunity to make a dent in our understanding of its pathophysiology, because of the varied and temporally haphazard application of our diagnostic techniques. We need to change our modus operandi.

Prevalence, Consequences, and Implications for Clinical Trials of Unrecognized Myocardial Infarction
Patients with myocardial infarction (MI) generally present with chest pain or pressure at rest or minimal exertion and have associated electrocardiographic changes and/or elevation of the biomarkers of myocardial necrosis. A subset of patients, however, experience little chest discomfort or do not present to medical attention despite experiencing symptoms. Unrecognized MI might be detected using electrocardiographic or imaging techniques, such as echocardiography, nuclear imaging, or cardiovascular magnetic resonance imaging. Unrecognized MI is a common clinical entity, with an incidence as great as 35% in high-risk popula...

Echocardiogram Versus Cardiac Magnetic Resonance Imaging for Assessing Systolic Function of Subaortic Right Ventricle in Adults With Complete Transposition of Great Arteries and Previous Atrial Switch Operation
In adults with congenital heart disease and a systemic right ventricle, subaortic ventricular systolic dysfunction is common. Echocardiographic assessment of systolic right ventricular (RV) function in these patients is important but challenging. The aim of the present study was to assess the reliability of conventional echocardiographic RV functional parameters to quantify the systolic performance of a subaortic right ventricle. We compared 56 contemporary echocardiograms and cardiac magnetic resonance studies in 37 adults, aged 26.9 ± 7.4 years, with complete transposition and a subaortic right ventricle. The fractional...

Utility of Transmural Myocardial Strain Profile for Prediction of Early Left Ventricular Dysfunction in Patients With Duchenne Muscular Dystrophy
Myocardial damage in Duchenne muscular dystrophy (DMD) has lethal outcomes, making early detection of myocardial changes in patients with DMD vital, because early treatment can help prevent the development of myocardial fibrosis. The aim of the present study was, therefore, to test the hypothesis that transmural strain profile (TMSP) analysis can predict future left ventricular (LV) dysfunction in patients with DMD with preserved ejection fraction. We studied 82 consecutive patients with DMD without LV wall motion abnormality, with an ejection fraction of 60 ± 5% (all ≥55%) and age 11 ± 3 years. Echocardiography was pe...

Association of Hyponatremia and Elevated Copeptin With Death and Need for Transplantation in Ambulatory Patients With Chronic Heart Failure
In conclusion, marked elevations of copeptin, particularly in serial measurements, are independent predictors of poor outcomes. The combination of elevated copeptin with hyponatremia, when adjusted for BNP and cTnT, is an even stronger predictor. These markers appear to reflect activation of the arginine vasopressin system present even in the absence of overt clinical changes. A strategy of serial monitoring of copeptin in combination with hyponatremia may be valuable in identifying higher risk patients with heart failure.
