Background . While only a small minority of patients undergo coronary artery bypass surgery (CABG) in the setting of cardiogenic shock (CS), these patients face a high risk for mortality and morbidity. There exist few studies that characterize clinical features and outcomes in CS patients undergoing CABG in contemporary community practice. Methods . We evaluated data of 14,956 patients with CS in comparison with 693637 without CS undergoing CABG between 2002 and 2005 at hospitals participating in the Society of Thoracic Surgeons National Database. Clinical, angiographic and operative features and in-hospital outcomes were studied in patients with and without CS. Results . Patients with preoperative CS constituted 2.1% of patients undergoing CABG yet accounted for 16% of all CABG deaths. These patients had greater comorbid conditions and left main disease and lower left ventricular ejection fraction. In-hospital events and length of hospital stay (median 96 vs. 36 days) were significantly higher in CS patients. Operative mortality was high (rising from 20% for isolated CABG, to 33% for CABG+ valve surgery, to 58% for CABG+ ventricular septal repair). While mortality for CABG surgery overall has declined significantly overtime (p for trend< .0001), mortality for CS patients have not changed significantly over the 4 year study period (p= .07, Figure ). Conclusions . Patients with CS represents minority of patients undergoing CABG, yet with persistently high operative risks. These patients in fact account for 1 of every 7 deaths in patients undergoing CABG. Ongoing efforts are warranted to continuously develop and evaluate new strategies to improve outcomes of these patients.

Aim. To develop novel strategies of patients selection and risk stratification after coronary artery bypass surgery before starting aerobic cardiorespiratory training programs. Material and methods. One hundred thirty seven patients 4 weeks after coronary artery bypass surgery were included in our study. RARE scale (risk of activity related events), ergospirometric test, FIT treadmill score and certain laboratory parameters like hemoglobin and alaninaminotransferase were used. Results. Logical interdependence is revealed between certain indicators of cardiorespiratory capacity and risk of developing unfavorable events due to aerobic training activities. Comprehensive protocol is developed based on multifactorial regression analysis, which allows to differentiate patients into low and high class of readiness to physical activities, including aerobic cardiorespiratory training programs. Conclusion. The protocol includes following variables METs, RARE scale, FIT treadmill score, left ventricular ejection fraction, hemoglobin and alaninaminotransferase levels. It is very userfriendly, easy, practical and efficient.

Background: Neuropeptide Y (NPY) and its receptors, NPY1R, NPY2R, and NPY5R, Substance P (SP) and its receptor Neurokinin 1R (NK1R) and calcitonin gene related peptide (CGRP), are important regulators of cardiac physiology, including: vasomodulation, cardiomyocyte hypertrophy, ischemia-induced angiogenesis, modulation of Protein Kinase C activity and calcium homeostasis.[[Unable to Display Character: ]] Objective: To determine the relationship between cardiac function and neuropeptide expression in human subjects. Methods: 38 consecutive patients undergoing elective, on pump, coronary artery bypass surgery (CABG) for coronary artery occlusive disease were studied. A Transesophageal Echo was performed immediately following induction of anesthesia and Left Ventricular Ejection Fraction (LVEF) was determined by AHA criteria as Normal, >55% (NLVEF, n = 26) or Low, <50% (LLVEF, n = 12). Patients with HbA1c>6.0 were considered diabetic. Right atrial tissue was obtained at the time of cannulation and the mRNA expression of Pre-Pro-NPY, NPY1R, NPY2R, NPY5R, Pre-Pro-SP, NK1R and CGRP was determined with qRT-PCR. Data are expressed as fold change relative to the NLVEF group. Results: The results of this study are summarized in the table below. Conclusions: 1. There is a strong association of LLVEF with diminished expression of SP, NK1R and NPY5R, with a similar trend for NPY2R. 2. LLVEF was not associated with HbA1c or diabetes status. 3. The consequences of diminished cardiac neuropeptide expression, the mechanisms involved, the relationship to cardiac autonomic neuropathy, with or without diabetes, warrant priority as an investigational initiative.
