Introduction : It is estimated that approximately 10–24% of acute ischemic stroke (AIS) patients have comorbid heart failure (HF). However, it is currently unknown if certain clinical risk factors associated with rtPA thrombolytic therapy differ based on HF diagnosis. The purpose of this study is to determine the clinical factors associated with rtPA inclusion in AIS patients with and without heart failure. Methods : Retrospective data for baseline clinical and demographic factors from January 2010 to January 2016 in a regional stroke center were analyzed. Of the 5,469 patients identified with AIS, 590 presented with heart failure while 4,879 did not. Odds ratios and 95% confidence intervals were used to determine which clinical factors were associated with rtPA inclusion. Results : Adjusted multivariate analysis demonstrated that within the AIS population, those without HF who received rtPA were more likely to be associated with Hispanic ethnicity (OR = 0.464, 95% CI, 0.247‐0.87, P = 0.017), coronary artery stenosis (OR = 0.55, 95% CI, 0.366‐0.83, P = 0.004), previous stroke (OR = 0.745, 95% CI, 0.609‐0.91, P = 0.004), previous TIA (OR = 1.447, 95% CI, 1.094‐1.91, P = 0.010), total cholesterol (OR = 1.487, 95% CI, 1.175‐1.88, P = 0.001), lipids (OR = 0.998, 95% CI, 0.996‐1, P = 0.038), serum creatinine (OR = 0.899, 95% CI, 0.854‐0.95, P<0.001), INR (OR = 0.825, 95% CI, 0.73‐0.93, P = 0.002), heart rate (OR = 0.13, 95% CI, 0.071‐0.24, P<0.001), and direct admission (OR = 2.87, 95% CI, 2.432‐3.39, P<0.001). AIS patients with HF who received rtPA were more likely to be associated with increasing age (OR = 0.982, 95% CI, 0.966‐1, P = 0.020), coronary artery disease (OR = 0.618, 95% CI, 0.391‐0.98, P = 0.0.040), INR (OR = 0.326, 95% CI, 0.129‐0.82, P = 0.018), and ambulatory improvement (OR = 1.69, 95% CI, 1.058‐2.7, P = 0.0.028). Conclusions : The results of this study demonstrate that within the AIS population, there are certain clinical risk factors that influence the likelihood of receiving rtPA in patients with and without HF. These findings provide further insight into AIS and HF and suggest the need for further research into the role the identified factors play in influencing clinical outcome.

<strong>Objective:</strong> We aimed to evaluate the risk factors associated with acute renal failure in patients who underwent coronary artery bypass surgery.<br /><strong>Methods:</strong> One hundred and six patients who developed renal failure after coronary artery bypass grafting (CABG) constituted the study group (RF group), while 110 patients who did not develop renal failure served as a control group <br />(C group). In addition, the RF group was divided into two subgroups: patients that were treated with conservative methods without the need for hemodialysis (NH group) and patients that required hemodialysis (HR group). Risk factors associated with renal failure were investigated.<br /><strong>Results:</strong> Among the 106 patients that developed renal failure (RF), 80 patients were treated with conservative methods without any need for hemodialysis (NH group); while <br />26 patients required hemodialysis in the postoperative period (HR group). The multivariate analysis showed that diabetes mellitus and the postoperative use of positive inotropes and adrenaline were significant risk factors associated with development of renal failure. In addition, carotid stenosis and postoperative use of adrenaline were found to be significant risk factors associated with hemodialysis-dependent renal failure (P &lt; .05). The mortality in the RF group was determined as 13.2%, while the mortality rate in patients who did not require hemodialysis and those who required hemodialysis was 6.2% and 34%, respectively.<br /><strong>Conclusion:</strong> Renal failure requiring hemodialysis after CABG often results in high morbidity and mortality. Factors affecting microcirculation and atherosclerosis, like diabetes mellitus, carotid artery stenosis, and postoperative vasopressor use remain the major risk factors for the development of renal failure.<br /><br />
