Prognostic role of stress cardiac magnetic resonance in the elderly

ConclusionsModerate to severe perfusion defects in stress CMR strongly predict cardiovascular events in people older than 70 years, without relevant adverse effects.ResumenIntroducción y objetivosDiferentes estudios han demostrado el valor diagnóstico y pronóstico de la resonancia magnética cardiaca (RMC) de estrés en pacientes con cardiopatía isquémica. No obstante, la evidencia en ancianos es escasa, en parte por las limitaciones de las técnicas diagnósticas disponibles para esta población. El objetivo de este estudio es evaluar la utilidad de la RMC de estrés en pacientes ancianos.MétodosSe estudió de manera prospectiva a los pacientes remitidos a una RMC de estrés para descartar isquemia miocárdica. Se consideró paciente anciano a los mayores de 70 años. El estudio de RMC de estrés se realizó conforme a los protocolos internacionales. La gravedad de la hipoperfusión se clasificó en función de los segmentos afectados: ligera (1-2 segmentos), moderada (3-4 segmentos) o grave (> 4 segmentos). Se analizó la aparición de eventos mayores durante el seguimiento (muerte, síndrome coronario agudo o revascularización). La supervivencia se analizó con el método de Kaplan-Meier y un modelo de regresión multivariante de Cox.ResultadosDe la cohorte inicial de 333 pacientes, 110 eran ...

Abstract Adipose-derived stromal cell (ASC) therapy is currently investigated as a new treatment option for patients with ischemic heart disease (IHD). The aim of this study was to evaluate the effect of ASC therapy in patients with chronic IHD measuring myocardial perfusion and cardiac function using cardiac magnetic resonance imaging (CMRI). Patients were included in MyStromalCell trial, a phase II, randomized, double-blinded, placebo-controlled study investigated the effect of ASCs in patients with chronic IHD with preserved left ventricular ejection fraction (LVEF). In total, 41 of 60 patients underwent cine, ...

AbstractWomen with angina and no obstructive coronary artery disease (CAD) have worse cardiovascular prognosis than asymptomatic women. Limitation in myocardial perfusion caused by coronary microvascular dysfunction (CMD) is one of the proposed mechanisms contributing to the adverse prognosis. The aim of this study was to assess myocardial perfusion in symptomatic women with no obstructive CAD suspected for CMD compared with asymptomatic sex-matched controls using static CT perfusion (CTP). We performed a semi-quantitative assessment of the left ventricular myocardial perfusion and myocardial perfusion reserve (MPR), using...

Surgical treatment to rebuild a dual coronary system is recommended at the time of the diagnosis. However, no effective operative pro...

AbstractCardiovascular computer tomography (CT) in pediatric congenital heart disease (CHD) patients is often challenging. This might be due to limited patient cooperation, the high heart rate, the complexity and variety of diseases and the need for radiation dose minimization. The recent developments in CT technology with the introduction of the third-generation dual-source (DS) dual-energy (DE) CT scanners well suited to respond to these challenges. DSCT is characterized by high-pitch, long anatomic coverage and a more flexible electrocardiogram-synchronized scan. DE provides additional clinical information about vascula...

AbstractPurpose of reviewThere are numerous gender- and sex-based differences that contribute to the increased morbidity and mortality related to atherosclerotic cardiovascular disease (ASCVD) in women. Early detection of risk and targeted management of atherosclerotic disease is fundamental to reduce ASCVD risk and improve outcomes in women. In this review, we examine the utility of cardiac computed tomography (CT) and coronary CT angiography (CTA) in three ASCVD scenarios including coronary artery calcium scoring for risk stratification in asymptomatic women, and coronary CTA for diagnosis and prognosis of stable ischemi...

CONCLUSIONS: Although GORD is common in subjects with ACS, we have not been able to show that GORD may serve as a trigger for ischaemia in these subjects. PMID: 31591635 [PubMed - as supplied by publisher]

This study is used to determine whether the VSD can be closed during surgery. A collateral flow study circuit is also set up for first-time operations to measure the residual collateral flow after all of the MAPCAs have been harvested. Patients who require midline unifocalization will invariably require very lengthy periods of support on cardiopulmonary bypass. We have adapted our perfusion circuitry to prepare for the demands on the bypass circuit to meet the requirements of this patient population. Our institution has developed a systematic approach for the conduct of perfusion to best serve our patients presenting with ...

A 50-something woman with history of CHF of unknown etiology, and of HTN, presented for evaluation of chest pressure.Her BP was 223/125, Sp02 98% on RA. HR 106, RR 18. Here was her ED ECG:There is sinus rhythm with Left Bundle Branch Block (LBBB)There is a large amount of ST Elevation in V2 and V3 (more than 5 mm)Thus, this meets the unweighted Sgarbossa Criteria of 5 mm of discordant ST ElevationBut it does NOT meet the Smith Modified Sgarbossa Criteria, which depend on the ST/S ratio.This ratio is critical because LBBB with very large depolarization voltage (QRS) also has very large repolarization voltage (ST/T).Her...

ConclusionThis study highlights the high prevalence of unidentified or poorly controlled VRF in people with mild cognitive symptoms attending a memory service. Given its importance to brain health and mitigation of future cognitive decline, a structured focus on identifying and managing these VRF in this setting is necessary. Exercise-based lifestyle programs should be embedded in post-diagnostic services for this population.

CONCLUSION: Surgical treatment of infective endocarditis showed good results in our center. The independent predictors of 30-day postoperative mortality for patients who underwent cardiac surgery for infective endocarditis were age, body mass index, ischemic heart disease, prolonged aortic cross-clamp and cardiopulmonary bypass time, Staphylococcus aureus infection, paravalvular abscess, and septic or cardiogenic shock.
