Article Synopsis
  • Acute kidney injury (AKI) is a significant concern for patients undergoing primary percutaneous coronary intervention (PCI) due to its impact on long-term outcomes in those suffering from STEMI.
  • This study analyzed data from the SAFARI-STEMI trial, comparing the incidence of AKI in patients who underwent PCI via radial artery (RA) versus femoral artery (FA) access.
  • The results showed no significant difference in AKI rates between the two access methods, suggesting that the choice of access site may not influence AKI occurrence in STEMI patients as previously thought.

In clinical practice, cancer management does not consistently encompass screening and identification of cardiovascular (CV) risk. The use of androgen deprivation therapy (ADT) in prostate cancer has been associated with increased CV risk and development of metabolic syndrome, necessitating identification of patients at risk in this population (e.g.

Aims: Cardiac allograft vasculopathy (CAV) is a leading cause of death in orthotopic heart transplant (OHT) survivors. Effective non-invasive screening methods are needed. Our aim was to investigate the added diagnostic and prognostic value of myocardial blood flow (MBF) to standard myocardial perfusion imaging (MPI) with positron emission tomography (PET) for CAV detection.

There is variability in guideline recommendations for assessment of the right ventricle (RV) with imaging as prognostic information after acute pulmonary embolism (PE). The objective of this study is to identify a clinical scenario for which normal CT-derived right-to-left ventricular (RV/LV) ratio is sufficient to exclude RV strain or PE-related short-term death. This retrospective cohort study included 579 consecutive subjects (08/2003-03/2010) diagnosed with acute PE with normal CT-RV/LV ratio (<0.

Chemotherapy-induced cardiomyopathy (CCMP) is a significant cause of morbidity and mortality. Compared to cardiomyopathy due to other causes, anthracycline-induced cardiomyopathy is associated with a worse survival. As cancer survival improves, patients with CCMP can be expected to comprise a significant proportion of patients who may require advanced therapies such as inotropic support, cardiac transplantation, or left ventricular assist device (LVAD).

We report the case of a 56-year-old woman with no significant medical history who was diagnosed with recurrent Takotsubo cardiomyopathy with variations in ventricular regional involvement including the classic and inverted patterns. She presented on 3 separate occasions with these findings; emotional stressors provoked all presentations. We present echocardiography, cardiac catheterization, and magnetic resonance images from her consecutive presentations.

Purpose: The aim of the study was to compare the prognostic value of right ventricular (RV) dysfunction detected on computed tomography pulmonary angiography (CTPA) and transthoracic echocardiography (TTE) in patients with acute pulmonary embolism (PE).

Materials And Methods: From all consecutive CTPAs performed between August 2003 and May 2010 that were positive for acute PE (n=1744), those with TTE performed within 48 hours of CTPA (n=785) were selected as the study cohort. Multivariate logistic regression analysis was performed to assess the association of CTPA RV/left ventricular (LV) diameter ratio and TTE RV strain with PE-related 30-day mortality, including other associated factors as covariates.

Purpose: To evaluate the correlation between the computed tomography (CT)-derived right ventricle (RV) to left ventricle (LV) diameter ratio and the RV size determined by echocardiography in patients with acute pulmonary embolism.

Materials And Methods: Consecutive CT pulmonary angiography examinations (August 2003 to May 2010) from a single, large, urban teaching hospital were retrospectively reviewed. For a cohort of 777 subjects who underwent echocardiography within 48 hours of the CT acquisition, the qualitative RV size (divided into 5 categories) extracted from the echocardiography report was correlated with the CT-derived RV/LV diameter ratio.

Background: It has been shown that (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET) is useful in identifying inflamed plaque in major arteries. This study evaluated the feasibility of inflamed plaque detection with routinely acquired cardiac FDG-PET viability studies in patients with severe coronary artery disease and left ventricular dysfunction.

Methods: Clinically indicated myocardial viability scans using FDG and PET combined with computed tomography from 103 patients were retrospectively analyzed for FDG uptake in the proximal, ascending, and descending thoracic aorta.

Neurohormonal activation in patients with heart failure is dominated by the deleterious long-term effects of activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system. The natriuretic peptides, including brain natriuretic peptide (BNP) and atrial natriuretic peptide (ANP), are also upregulated in heart failure, and partially counteract these deleterious effects by promoting vasodilation, natriuresis, and diuresis. Although BNP has been established as an important biomarker in the diagnosis and prognosis of heart failure, growing evidence suggests that measurement of plasma ANP, specifically its metabolite mid-regional pro-ANP, has similar diagnostic and prognostic value.

A single imaging modality that can accurately assess both coronary anatomy and mitral valve (MV) anatomy prior to surgery may be desirable. We sought to determine the diagnostic accuracy of cardiac computed tomography (CT) to detect and characterize mitral valve prolapse (MVP) compared to echocardiography. Consecutive patients referred for 'single-source' cardiac CT for investigation prior to non-coronary cardiac sugery were identified.

Purpose Of Review: This review will provide an overview of the genetic basis of cardiomyopathy with an emphasis on the clinically relevant breakthroughs that have occurred recently and their role in the evaluation of patients with cardiomyopathy.

Recent Findings: Recent developments that have occurred in genetic cardiomyopathy include the finding of a shared genetic basis of familial dilated cardiomyopathy in at least a subset of cases of peripartum cardiomyopathy; the increased yield for the diagnosis of arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) when genetic testing is incorporated into Task Force Criteria; and the value of testing a spectrum of implicated genes in hypertrophic cardiomyopathy and ARVC because of the severe phenotype associated with compound mutations.

Summary: Recent progress in genetic cardiomyopathy points to the potential value of genetic testing in shaping the clinician's ability to diagnose and understand the pathogenetic basis of the inherited cardiomyopathies.

Objective: Since evidence-based guidelines for the treatment of acute supraventricular tachyarrhythmia (SVT) in pregnancy are not available, our objective was to document published reports and immediate outcomes in this patient population.

Data Sources: A search of the literature was performed using Medline, Embase, CINAHL, American College of Physicians Journal Club, Database of Abstracts of Reviews of Effects, and Cochrance Central Register of Controlled Trials, using key word searching and citations in the English language literature from January 1950 to March 2010, on the subject of SVT.

Study Selection/data Extraction: We reviewed 38 studies (case-controlled cohort studies, case series, and case reports) using the key words "supraventricular tachycardia," "paroxysmal tachycardia," and "atrial tachycardia," combined with "pregnancy" or "pregnancy complications.

In developed countries, coronary artery disease (CAD) continues to be a major cause of death and disability. Over the past two decades, positron emission tomography (PET) imaging has become more widely accessible for the management of ischemic heart disease. Positron emission tomography has also emerged as an important alternative perfusion imaging modality in the context of recent shortages of molybdenum-99/technetium-99m ((99m)Tc).

Background: Screening echocardiography (ECHO) is commonly performed to determine whether the patient's left ventricular ejection fraction (LVEF) is appropriate for primary prophylactic implantable cardiac defibrillator (ICD) referral. However, radionuclide ventriculography (RNA) is used by many implantation centres for decision making.

Objective: To determine whether current screening ECHO techniques are effective in identifying patients suitable for primary prophylactic ICD referral.

Spontaneous coronary artery dissection is an unusual cause of acute myocardial ischemia. The natural history of spontaneous coronary artery dissection that persists on angiography after the acute event has not been well characterized. A case of a 36-year-old man who presented with monomorphic ventricular tachycardia 12 years following a myocardial infarction that occurred during his last course of bleomycin-etoposide-cisplatin therapy for testicular cancer is reported.
