Impact of percutaneous coronary intervention on patients with impaired baseline renal function.

ABSTRACT: BACKGROUND:Acute kidney injury (AKI) frequently co-prevails with acute coronary syndromes (ACS), which could improve post percutaneous coronary intervention (PCI). We sought to evaluate the impact of PCI on post-procedural renal function in patients with impaired baseline serum creatinine (Cr). METHODS:Retrospective evaluation of 185 patients undergoing PCI with impaired basal serum Cr (? 1.5 mg/dl) was done, including 88 (47.5%) patients with recent ACS (?2 weeks old) in group I and 97 (52.4%) patients in group II (stable angina or ACS >2 weeks old). Patients were classified into worsening or improving renal function based on a corresponding increase or decrease of ?0.5 mg/dl (?Cr) in serum Cr 24-48 h post PCI. ?Cr < 0.5 mg/dl was termed as no change. RESULTS:A trend towards improving renal function was seen in the study cohort (mean serum Cr: 2.37 ± 1.25 mg/dl vs 2.28 ± 1.59 mg/dl); (p = 0.09) with decrease in group I from 2.28 ± 1.09 mg/dl to 2.12 ± 1.44 mg/dl (p = 0.03) and in group II from 2.45 ± 1.38 mg/dl to 2.43 ± 1.71 mg/dl (p = 0.81). Post PCI, worsening occurred in 20/185 (10.8%) patients in the total study cohort, 5/88 (5.6%) in group I and 15/97 (15.4%) in group II (p = 0.03). Improvement in serum Cr was seen in 49/185 (26.4%) in the total study cohort, 30/88 (34.1%) in group I and 19/97 (19.6%) patients in group II (p = 0.03). CONCLUSION:- Post PCI, only a small proportion of patients with impaired baseline creatinine showed worsening in renal function. Improved renal function was observed in at least one-third of the patients with recent ACS.

Project description:PurposeMalnutrition has been shown to be related to adverse clinical outcomes in patients with heart failure, hypertension, atrial fibrillation and other cardiovascular diseases. However, in the patients with coronary artery disease (CAD) undergoing percutaneous coronary interventions (PCI), especially in the elderly, the association of nutritional state and all-cause mortality remains unknown. We aimed to investigate the association of malnutrition with all-cause mortality in the elder patients undergoing PCI.Patients and methodsBased on the largest retrospective and observational cohort study from January 2007 to December 2017, the Controlling Nutritional Status (CONUT) score was applied to 21,479 consecutive patients with age ≥60 who undergoing PCI for nutritional assessment. Participants were classified as absent, mild, moderate and severe malnutrition by CONUT score. The Kaplan-Meier method was used to compare all-cause mortality among the above four groups. Multivariable Cox proportional hazard regression analyses were performed to examine the association of malnutrition with all-cause mortality.ResultsAccording to the CONUT score, 48.19%, 15.08% and 0.94% patients were mildly, moderately and severely malnourished, respectively. During a median follow-up of 5.16 years (interquartile range: 3.02 to 7.89 years), 3173 (14.77%) patients died. Kaplan-Meier analysis showed that the risk of all-cause mortality was significantly higher in patients with a worse nutritional status. Compared with normal nutritional state, malnutrition was associated with significantly increased risk for all-cause mortality (adjusted hazard ratio for mild, moderate and severe degrees of malnutrition, respectively: 1.20 [95% confidence interval (CI): 1.09 to 1.33], 1.32 [95% CI: 1.17 to 1.49] and 1.76 [95% CI: 1.33 to 2.33]).ConclusionMalnutrition is prevalent among elderly patients with CAD undergoing PCI, and is strongly related to the all-cause mortality increasing. For elderly patients with CAD undergoing PCI, it is necessary to assess the status of nutrition, and evaluate the efficacy of nutritional interventions.

Project description:BackgroundThrombocytopenia was intuitively considered to be associated with higher risk of bleeding and multiple comorbidities after percutaneous coronary intervention (PCI). However, controversial results exist, and the real-world clinical impact of thrombocytopenia in patients undergoing PCI is largely unknown. The aim of this study was to evaluate the influence of baseline thrombocytopenia on the prognosis of patients undergoing PCI.MethodsUsing the West China Hospital Inpatient Sample database, patients who underwent PCI were identified from August 2012 to January 2019. Baseline thrombocytopenia was defined as a preprocedural platelet count of 100 × 109/L or less obtained from a routine blood sample taken within 48 hours before coronary PCI. The clinical effect of the advanced thrombocytopenia group (≤85 × 109/L), according to the median value of platelet count in the thrombocytopenia cohort, was further assessed. The primary outcome was a composite of in-hospital death, bleeding events, and post-PCI transfusion.ResultsOf 9531 patients enrolled in our study, 936 had baseline thrombocytopenia and 8595 patients did not have. There were no significant differences in the primary outcome between the two groups. However, advanced thrombocytopenia was independently associated with higher risk of primary outcome (OR 1.67, 95% CI 1.06 to 2.65, p = 0.029). Acute coronary syndrome (ACS) patients with thrombocytopenia were associated with higher odds of major bleeding (BARC ≥ 2) (OR 2.56, 95% CI 1.24 to 5.44, p = 0.011). Compared with the nonthrombocytopenia group, the thrombocytopenia group with ticagrelor use had higher odds of major bleeding (OR 9.7, 95% CI 1.57 to 60.4 versus OR 0.22, 95% CI 0.03 to 1.69, interaction p = 0.025).ConclusionsIt seems feasible for patients with thrombocytopenia to receive PCI, but close attention should be paid to advanced thrombocytopenia, the risk of postprocedure bleeding in ACS patients, and the use of more potent P2Y12 inhibitor.
