TCT-361 Heart Team Approach to CAD Management in Patients Undergoing Elective Vascular Surgery Who Have Asymptomatic Ischemia-producing Coronary Sten…
2018
Patients undergoing peripheral vascular surgery (PVS) are at increased risk of post-op MI/death due to unrecognized CAD. Coronary CTA-derived fractional flow reserve (FFRCT) reliably identifies lesion-specific ischemia (LSI) in stable chest pain patients but has not been used in PVS patients. We

Pulmonale Thrombendarteriektomie bei thromboembolischer pulmonaler Hypertonie: Indikationen und Frühergebnisse
2008
Pulmonary thrombendarterectomy was performed in 32 patients (14 men and 18 women; mean age 38 +/- 15 years) with thromboembolic pulmonary hypertension (New York Heart Association stage III: n = 22; stage IV: n = 10). The preoperative arterial pO2 averaged 59 +/- 11 mm Hg; pulmonary vascular resistance (PVR) and mean pressure (MPAP) were increased to 1,045 +/- 430 dyn.s.cm-5 and 53 +/- 12 mm Hg, respectively. The perioperative death rate was 22% (7 of 32). In the 25 survivors the pulmonary hypertension was reduced to a PVR of 194 +/- 75 dys.s.cm-5, MPAP of 28 +/- 6 mm Hg. Subsequent re-examination in 15 patients (NYHA stage I: n = 14, stage II: n = 1) after a mean of 17 +/- 5 months demonstr…
Spectral decomposition of RR-variability obtained by an open loop parametric model for the diagnosis of neuromediate syncope
2002
The role of the cardiovascular regulatory mechanism in patients with neuromediate syncope (NS) is poorly understood. The aim of this study was to accomplish continuous non-invasive analysis of the baroreflex mechanism in patients during a head-tip tilt-table test (HTT) using an open-loop autoregressive model with exogenous input. The model describes the causal dependence of the RR interval on the systolic arterial pressure (SAP) variability. Thus, RR variability results as the linear composition of SAP-dependent (Pdep) and SAP-independent parts of the RR power (P). Further, the model allows the estimation of the baroreflex gain using the modulus of the transfer function (G) from SAP to RR i…
Body Mass Index and Cardiac Events in Elderly Patients
2009
Body Mass Index has been challenged as an anthropometric measurement in elderly patients. Recent data, even in elderly patients, has demonstrated that elevated body mass index affords a worse long-term prognosis, although the magnitude of this relationship weakens as one ages. Underweight patients, possibly due to elements of sarcopenia and/or frailty, are also at a higher risk of overall mortality. A number of inflammatory mediators may be responsible for such factors which likely contribute to the increased risk of cardiovascular events observed. Although body mass index has been implicated in the development of heart failure, coronary artery disease and mediates its effects through other…
Summary of the Effects of Exercise Therapy in Non-Communicable Diseases: Clinically Relevant Evidence from Meta-Analyses of Randomized Controlled Tri…
2021
There is strong evidence that exercise therapy leads to better measured and self-reported physical fitness and function in patients with chronic diseases, along with improvements in body composition. The evidence for other health benefits has not been summarized as systematically across different chronic diseases. Given the volume of research that has appeared in the past decade, this review of meta-analyses of randomized controlled trials (RCTs) in patients with specific chronic diseases summarizes the evidence regarding exercise therapy for various outcomes to help practitioners in prescribing exercise therapy for their patients. Meta-analyses published before Jan 1, 2021, based on at lea…

Serum Heat Shock Protein 60 in Acute Heart Failure: A New Biomarker?
2012
Heat shock protein 60 (HSP60) is a mitochondrial protein constitutively expressed in the majority of cells, and its expression is up-regulated by a variety of stressors. In heart failure, HSP60 is released from cardiomyocytes. The authors speculate that increased serum HSP60 (sHSP60) may be related to the severity of heart failure. This investigation sought to assess the association between sHSP60 and the composite end point of death ⁄ readmission in patients with acute heart failure (AHF). A total of 132 consecutive patients were admitted for AHF. The independent association between sHSP60 and the end point was assessed with Cox regression. During a median follow-up of 7 months (interquart…
