Background: Contrast-induced acute kidney Injury (CIAKI) also called nephropathy is one of the recurrent complications with very high mortality and morbidity rate amongst the patients undergoing percutaneous coronary intervention (PCI). The purpose of this research was to validate the incidence, risk factors, and correlation of various comorbidities with CIAKI.Methods: The study was conducted on 308 patients who had undergone PCI procedures. All patients were recruited following all ethical guidelines. All patients were treated as per the hospital protocol. All patients were followed up for 7 days post PCI. Out of 308 patients, 35 developed CIKAI while remaining was classified as control for post-hoc analysis comparison. Evaluation of the patients was done using Mehran’s risk score, ODD analysis and RADHIKa method.Results: The incidence of CIAKI was found in 35 (11.37%) out of 308 patients. No patients required dialysis within 1 week of the procedure. The use of the ionization optimized contrast medium (IOCM) is linked with the reduction of +CIAKI. The obvious relationship between the volume of contrast media, MRS, and CIAKI was reestablished. Post-hoc analysis of CIAKI and non-CIAKI revealed that the CIAKI is closely linked with heart failure as a risk factor. Congestive heart failure (CHF) increases the risk of CIAKI and that results in an increased risk of heart failure.Conclusion: In conclusion, the pre-existing multiple co-morbidities, volume, and ionization value of the contrast media were found to be directly associated with CIAKI.

Background: Contrast induced nephropathy remains important cause of hospital-acquired acute kidney injury and affects between 2% of the general population to 50% of high-risk subgroups following coronary intervention. Objectives: To determine the incidence and to study the various risk factors associated with CIN. Patients and Methods: In our study, total of 212 patients (154 males and 58 females) who received non ionic iso osmolar contrast media during percutaneous transluminal coronary intervention (PCI) were included. We diagnosed CIN by a relative increase of >25% or an absolute increase of >0.5 mg/dl in serum creatinine levels two days after procedure. Results: The incidence of CIN in our study was 15.1%. In univariate analysis: age >75 years, hypertention diabetes mellitus (DM), heart failure, hypotension, CKD [creatinine  >1.5mg/dl] and increased contrast volume were associated with increased  risk of CIN whereas,  gender, anemia and use of IABP failed to reach statistical significance. As the number of risk factor and/or volume of contrast increases, the incidence of CIN increases exponentially. Conclusion: Since there is no established treatment for CIN, all possible efforts should be taken to prevent it from occurring by identifying patients at risk. CIN is related with many risk factors, so whenever multiple risk factors are present in an individual patient, lowest dose of contrast should be used and adequate hydration should be given. Key Words: Contrast-induced nephropathy, Non ionic iso-osmolar contrast media, percutaneous coronary intervention.

Background: CIN has gained increased attention in the clinical setting, particularly during cardiac intervention but also in many other radiological procedures in which iodinated contrast media are used. There is at present good clinical evidence from well-controlled randomized studies that CIN is a common cause of acute renal dysfunction.Methodology: This was a prospective study conducted among the patients who underwent coronary angiography and percutaneous coronary intervention in the Department of Cardiology, Dhaka Medical College Hospital during January 2010 to December 2010. A total of 111 patients age range from 25 to 75 years were included in the study. Serum creatinine level at baseline and at the end of 48 hours was done in all these patients. Study population was divided into two groups according to development of acute kidney injury (AKI). Group-I = AKI, Group II = Not developed AKI. Results: AKI developed 11.7% of the study patient. DM and Preexisting renal insufficiency were significantly higher in group I patients. HTN was (61.5% Vs 44.9%) higher in group I but not significantly. History of ACE inhibitor/ARB, NSAID intake and LVEF <40% were significantly higher in group I patients. The mean±SD volume of CM (Contrast Media) were 156.9±44.8 ml and 115.4±30.0 ml in group I and group II respectively, which was significant. The mean±SD of serum creatinine after 48-72 hours of CAG/PCI was 1.4±0.37 mg/dl and 1.1±0.2 mg/dl in group I and group II respectively. The serum creatinine level increased significantly (p<0.05) after 48-72 hours of CAG/PCI in group I. In group II, S. creatinine level increased but not significant (p>0.05). Impaired renal function was found 76.9% and 2.0% in group I and group II respectively. DM, HTN, preexisting renal insufficiency, ACE inhibitor/ARB, NSAIDs, contrast volume (>150 ml), eGFR (<60 ml/min/ 1.73m2) and LVEF (<40%) are significantly (p0.05) associated for CIN development.Conclusion: CIN is an iatrogenic but preventable disorder results from the administration of contract media. Although rare in the general population, CIN occurs frequently in patients with underlying renal dysfunction and diabetes. In patients with pre angiographic normal renal function, the prevalence is low but in pre-existing renal impairment it may pose a serious threat. Thus risk factors are synergistic in their ability to predispose to the development of CIN. A careful risk-benefit analysis must always be performed prior to the administration of contrast media to patients at risk for CIN.

Whether contrast-associated acute kidney injury (CA-AKI) is only a bystander or a risk factor for mortality in older patients undergoing percutaneous coronary intervention (PCI) is not well understood. Data from FRASER (NCT02386124) and HULK (NCT03021044) studies have been analysed. All patients enrolled underwent coronary angiography. The occurrence of CA-AKI was defined based on KDIGO criteria. The primary outcome of the study was to test the relation between CA-AKI and 3-month mortality. Overall, 870 older ACS adults were included in the analysis (mean age 78 ± 5 years; 28% females). CA-AKI occurred in 136 (16%) patients. At 3 months, 13 (9.6%) patients with CA-AKI died as compared with 13 (1.8%) without it (p < 0.001). At multivariable analysis, CA-AKI emerged as independent predictor of 3-month mortality (HR 3.51, 95%CI 1.05–7.01). After 3 months, renal function returned to the baseline value in 78 (63%) with CA-AKI. Those without recovered renal function (n = 45, 37%) showed an increased risk of mortality as compared to recovered renal function and no CA-AKI subgroups (HR 2.01, 95%CI 1.55–2.59, p = 0.009 and HR 2.71, 95%CI 1.45–5.89, p < 0.001, respectively). In conclusion, CA-AKI occurs in a not negligible portion of older MI patients undergoing invasive strategy and it is associated with short-term mortality.

Background: An increasing number of cardiac centres are using immediate percutaneous coronary intervention (PCI) and extracorporeal cardiopulmonary resuscitation (ECPR) in patients with refractory out of hospital cardiac arrest (r-OHCA). Published evidence regarding PCI in OHCA has been mainly reporting to patients with early return of spontaneous circulation and the influence of PCI and ECPR on survival in the population of patients with r-OHCA and acute coronary syndrome (ACS) remains unclear. Methods: In this post hoc analysis of the randomized r-OHCA trial, all patients with ACS as a cause of r-OHCA were included. The effect of successful PCI and ECPR on 180-days survival was examined using Kaplan-Meier estimates and multivariable Cox regression. Results: In total, 256 patients were evaluated in Prague OHCA study and 127 (49.6 %) had ACS as the cause of r-OHCA constituting current study population. The mean age was 58 years (46.3-64) and duration of resuscitation was 52.5 minutes (36.5-68). ECPR was used in 51 (40.2 %) of patients. Immediate PCI was performed in 86 (67.7%) patients and TIMI flow 2 or 3 was achieved in 75 (87.2%) patients. The overall 180-days survival of patients with successful PCI was 40 % compared to 7.7 % with no or failed immediate PCI (log-rank p < 0.001). After adjustment for confounders, successful PCI was associated with a lower risk of death (HR 0.47, CI 0.24-0.93, p = 0.031). Likewise, ECPR was associated with a lower risk of death (HR 0.11, CI 0.05-0.24, p< 0.001). Conclusion: In this post hoc analysis of the randomized r-OHCA trial, successful immediate PCI as well as ECPR were associated with improved 180-days survival in patients with r-OHCA due to ACS.

Purpose: Septic shock (SS) manifests with profound circulatory and cellular metabolism abnormalities and has a high in-hospital mortality (25%-50%). Congestive heart failure (CHF) patients have underlying circulatory dysfunction and compromised cardiac reserve that may place them at increased risk if they develop sepsis. Outcomes in patients with CHF who are admitted with SS have not been well studied. Materials and Method: Retrospective cross sectional secondary analysis of the Nationwide Readmission Database (NRD) for 2016 and 2017. ICD-10 codes were used to identify patients with SS during hospitalization, and then the cohort was dichotomized into those with and without an underlying diagnosis of CHF. Results: Propensity match analyses were performed to evaluate in-hospital mortality and clinical cardiovascular outcomes in the 2 groups. Cardiogenic shock patients were excluded from the study. A total of 578,629 patients with hospitalization for SS were identified, of whom 19.1% had a coexisting diagnosis of CHF. After propensity matching, 81,699 individuals were included in the comparative groups of SS with CHF and SS with no CHF. In-hospital mortality (35.28% vs 32.50%, P < .001), incidence of ischemic stroke (2.71% vs 2.53%, P = .0032), and acute kidney injury (69.9% vs 63.9%, P = .001) were significantly higher in patients with SS and CHF when compared to those with SS and no CHF. Conclusions: This study identified CHF as a strong adverse prognosticator for inpatient mortality and several major adverse clinical outcomes. Study findings suggest the need for further investigation into these findings’ mechanisms to improve outcomes in patients with SS and underlying CHF.

Protein-energy wasting (PEW) is particularly common in patients with acute kidney injury (AKI). It is correlated, at least in part, with specific factors of the reduction of renal function and is associated with significant increase in mortality and morbidity. In this clinical condition, the optimal nutritional support remains an open question due to its qualitative composition in terms of macro- and micronutrients. In fact, data on critically ill patients have confirmed that nutritional support targeting the real protein and energy needs is associated with improvement of clinical outcome. However, data available in AKI patients are still scarce. AKI is characterized by increased risk of both under- and overfeeding because of the coexistence of many factors that can influence the evaluation of nutrient needs, such as a rapid change in body weight due to alterations in fluid balance, loss of nutrients during renal replacement therapy (RRT), and the presence of hidden calories in the RRT (ie, calories derived from anticoagulants and/or from solutions used in the different dialysis methods). As AKI comprises a highly heterogeneous group of patients, with oscillatory nutrient needs during patients’ clinical course, nutritional requirements should be frequently reassessed, individualized, and carefully integrated with RRT. Nutrient needs in patients with AKI can be difficult to estimate and should be directly measured, especially in the intensive care unit setting.

The prevention of symptomatic heart failure represents the treatment of patients in the A and B stages of AHA/ACC heart failure classification. Stage A refers to patients without structural heart disease but at risk to develop chronic heart failure. The major risk factors in stage A are hypertension, diabetes, atherosclerosis, family history of coronary artery disease and history of cardiotoxic drug use. In this stage, blockers hypertension is the primary area in which beta blockers may be useful. Beta blockers seem not to be superior to other medication in reducing the development of heart failure due to hypertension. Stage B heart failure refers to structural heart disease but without symptoms of heart failure. This includes patients with asymptomatic valvular disease, asymptomatic left ventricular (LV) dysfunction, previous myocardial infarction with or without LV dysfunction. In asymptomatic valvular disease no data are available on the efficacy of beta blockers to prevent heart failure. In asymptomatic LV dysfunction only few asymptomatic patients have been enrolled in the trials which tested beta blockers. NYHA I patients were barely 228 in the MDC, MERIT and ANZ trials altogether. The REVERT trial was the only trial focusing on NYHA I patients with LV ejection fraction less than 40%. Metoprolol extended release on top of ACE inhibitors ameliorated LV systolic volume and ejection fraction. A post hoc analysis of the SOLVD Prevention trial demonstrated that beta blockers reduced death and development of heart failure. Similar results were reported in post MI patients in a post hoc analysis of the SAVE trial (Asymptomatic LV failure post myocardial infarction). In the CAPRICORN trial about 65% of the patients were not taking diuretics and then could be considered asymptomatic. The study revealed a reduction in mortality and a non-significant trend toward reduction of death and hospital admission for heart failure. Conclusions: beta blockers are not specifically indicated in stage A heart failure. On the contrary, in most of the stage B patients, and particularly after MI, beta blockers are indicated to reduce mortality and, probably, also the progression toward symptomatic heart failure.

Background.Uric acid can acutely activate various inflammatory transcription factors. Since high levels of oxyradicals and lower antioxidant levels in septic patients are believed to result in multiorgan failure, uric acid levels could be used as a marker of oxidative stress and poor prognosis in patients with sepsis.Design.We conducted a prospective cohort study on Medical Intensive Care Unit (MICU) patients and hypothesized that elevated uric acid in patients with sepsis is predictive of greater morbidity. The primary end point was the correlation between hyperuricemia and the morbidity rate. Secondary end points were Acute Kidney Injury (AKI), mortality, Acute Respiratory Distress Syndrome (ARDS), and duration of stay.Results.We enrolled 144 patients. 54 (37.5%) had the primary end point of hyperuricemia. The overall morbidity rate was 85.2%. The probability of having hyperuricemia along with AKI was 68.5% and without AKI was 31.5%. Meanwhile the probability of having a uric acid value <7 mg/dL along with AKI was 18.9% and without AKI was 81.1% (pvalue < 0.0001).Conclusion.We report that elevated uric acid levels on arrival to the MICU in patients with sepsis are associated with poor prognosis. These patients are at an increased risk for AKI and ARDS.

Background. The early detection of wearing-off in Parkinson disease (DEEP) observational study demonstrated that women with Parkinson’s disease (PD) carry an increased risk (80.1%) for wearing-off (WO). This post hoc analysis of DEEP study evaluates gender differences on WO and associated phenomena.Methods. Patients on dopaminergic treatment for ≥1 year were included in this multicenter observational cross-sectional study. In a single visit, WO was diagnosed based on neurologist assessment as well as the use of the 19-item wearing-off questionnaire (WOQ-19); WO was defined for scores ≥2. Post hoc analyses were conducted to investigate gender difference for demographic and clinical features with respect to WO.Results. Of 617 patients enrolled, 236 were women and 381 were men. Prevalence of WO was higher among women, according to both neurologists’ judgment (61.9% versus 53.8%,P=0.045) and the WOQ-19 analysis (72.5% versus 64.0%,P=0.034). In patients with WO (WOQ-19), women experienced ≥1 motor symptom in 72.5% versus 64.0% in men and ≥1 nonmotor symptom in 44.5% versus 36.7%, in men.Conclusions. Our results suggest WO as more common among women, for both motor and nonmotor symptoms. Prospective studies are warranted to investigate this potential gender-effect.
