Chronic kidney disease and the outcomes of fibrinolysis for ST-segment elevation myocardial infarction: A real-world study.

ABSTRACT:

Background

In low-resource regions, fibrinolytic therapy is often the only option for ST-elevation myocardial infarction (STEMI) patients as primary percutaneous coronary intervention (PCI) is often not available and patients are hardly transferred to a medical center with PCI capacity within the first 120 minutes. Chronic kidney disease (CKD) is one of the most frequently encountered complications of STEMI. However, the evidence for the efficacy of fibrinolytic therapy in STEMI patients with CKD is still limited. The aim of this study is to test whether CKD modifies the association between fibrinolytic therapy and short-term major adverse cardiovascular events (MACEs) among patients with STEMI.

Methods and findings

This is a real-world study analyzing the data from 9508 STEMI patients (mean age: 64.0±12.4 years; male: 70.1%) in the third phase of Clinical Pathways in Acute Coronary Syndromes program (CPACS-3), which is a large study of the management of acute coronary syndromes (ACS) in 101 county hospitals without PCI capacity in China. CKD was defined as an estimated glomerular filtration rate of less than 60 mL/min per 1·73 m2 at the admission. The primary outcome is short-term MACEs, including all-cause death, recurrent myocardial infarction, or nonfatal stroke. Patients were recruited consecutively between October 2011 and November 2014. Out of them, 1282 patients (13.5%) were classified as having CKD. Compared with non-CKD patients, CKD patients were less likely to receive fibrinolytic therapy than non-CKD patients (26.4% vs. 38.9%, P<0.001), more likely to experience a failed fibrinolytic therapy (32.8% vs. 16.9%), and had a higher risk of short-term MACEs (19.7% vs. 5.6%). After full adjustment, use of fibrinolytic therapy was associated with a significantly lower risk of short-term MACEs in non-CKD patients (relative risk [RR] = 0.87, 95% confidence interval [CI]: 0.76-0.99), but not in CKD patients (P for interaction = 0.026). Further analysis stratified by the success of fibrinolysis showed that compared with patients who did not receive fibrinolytic therapy, patients with successful fibrinolysis had a lower risk of short-term MACEs that was similar between patients with (RR = 0.71, 95% CI: 0.55-0.82) and without CKD (RR = 0.67, 95% CI: 0.55-0.92), while patients with unsuccessful fibrinolysis had a similarly higher risk in CKD patients (RR = 1.25, 95% CI: 1.09-1.43) and non-CKD patients (RR = 1.30, 95% CI: 1.13-1.50).

Conclusions

CKD reduced the likelihood of successful fibrinolysis and increased the risk of short-term MACEs in patients with STEMI. Attention should be paid to how to improve the success rate of fibrinolytic therapy for STEMI patients with CKD.

Project description:AimsThere are limited contemporary data on the use of initial fibrinolysis in ST-segment elevation myocardial infarction cardiogenic shock (STEMI-CS). This study sought to compare the outcomes of STEMI-CS receiving initial fibrinolysis vs. primary percutaneous coronary intervention (PPCI).MethodsUsing the National (Nationwide) Inpatient Sample from 2009 to 2017, a comparative effectiveness study of adult (>18 years) STEMI-CS admissions receiving pre-hospital/in-hospital fibrinolysis were compared with those receiving PPCI. Admissions with alternate indications for fibrinolysis and STEMI-CS managed medically or with surgical revascularization (without fibrinolysis) were excluded. Outcomes of interest included in-hospital mortality, development of non-cardiac organ failure, complications, hospital length of stay, hospitalization costs, use of palliative care, and do-not-resuscitate status.ResultsDuring 2009-2017, 5297 and 110 452 admissions received initial fibrinolysis and PPCI, respectively. Compared with those receiving PPCI, the fibrinolysis group was more often non-White, with lower co-morbidity, and admitted on weekends and to small rural hospitals (all P < 0.001). In the fibrinolysis group, 95.3%, 77.4%, and 15.7% received angiography, PCI, and coronary artery bypass grafting, respectively. The fibrinolysis group had higher rates of haemorrhagic complications (13.5% vs. 9.9%; P < 0.001). The fibrinolysis group had comparable all-cause in-hospital mortality [logistic regression analysis: 28.8% vs. 28.5%; propensity-matched analysis: 30.8% vs. 30.3%; adjusted odds ratio 0.97 (95% confidence interval 0.90-1.05); P = 0.50]. The fibrinolysis group had comparable rates of acute organ failure, hospital length of stay, rates of palliative care referrals, do-not-resuscitate status use, and lesser hospitalization costs.ConclusionsThe use of initial fibrinolysis had comparable in-hospital mortality than those receiving PPCI in STEMI-CS in the contemporary era in this large national observational study.

Project description:BackgroundEarly reperfusion of the coronary artery has become the first choice for patients with ST-segment elevation myocardial infarction (STEMI). How to deal with patients who miss the time window for early reperfusion is still controversial. Based on real-world data, this study was conducted to explore whether percutaneous coronary intervention (PCI) has an advantage over standard drug therapy in patients who miss the optimal treatment window.MethodsConsecutive patients who were diagnosed with STEMI and met the inclusion criteria between 2009 and 2018 in our center were retrospectively included in this cohort study. The primary endpoint events were major adverse cardiac events (MACEs), including heart failure, sudden cardiac death, malignant arrhythmia, thrombi and bleeding events during the period of admission. Secondary endpoint events were components of MACEs. At the same time, we also evaluated angina pectoris at admission and discharge through Canadian Cardiovascular Society (CCS) grading.ResultsThis study enrolled 417 STEMI patients and divided them into four groups (PCI < 3 days, 14.87%; 3 days<PCI < 7 days, 21.104%; PCI > 7 days, 34.29%; MED, 29.74%). During the period of admission, MACEs occurred in 52 cases. The incidence of MACEs was 11.29, 7.95, 4.20 and 25.81% in the four respective groups (p < 0.0001). The MED group had higher rates of MACEs (OR = 3.074; 95% CI 0.1.116-8.469, p = 0.03) and cardiac death (OR = 3.027; 95% CI 1.121-8.169, p = 0.029) compared to the PCI group. Although both treatments were effective in improving CCS grade at discharge, the PCI group improved more significantly (p < 0.0001).ConclusionsIn the real world, delayed PCI can be more effective in patients with angina symptoms at discharge and reduce the incidence of MACEs and cardiac death during hospitalization. The timing of intervention was independent of the occurrence of MACEs during hospitalization and of improvement in symptoms.

Project description:Background The role of invasive management compared with medical management in patients with non-ST-segment-elevation myocardial infarction (NSTEMI) and advanced chronic kidney disease (CKD) is uncertain, given the increased risk of procedural complications in patients with CKD. We aimed to compare clinical outcomes of invasive management with medical management in patients with NSTEMI-CKD. Methods and Results We identified NSTEMI and CKD stages 3, 4, 5, and end-stage renal disease admissions using International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes from the Nationwide Readmission Database 2016 to 2018. Patients were stratified into invasive and medical management. Primary outcome was mortality (in-hospital and 6 months after discharge). Secondary outcomes were in-hospital postprocedural complications (acute kidney injury requiring dialysis, major bleeding) and postdischarge 6-month safety and major adverse cardiovascular events. Out of 141 052 patients with NSTEMI-CKD, 85 875 (60.9%) were treated with invasive management, whereas 55 177 (39.1%) patients were managed medically. In propensity-score matched cohorts, invasive strategy was associated with lower in-hospital (CKD 3: odds ratio [OR], 0.47 [95% CI, 0.43-0.51]; P<0.001; CKD 4: OR, 0.79 [95% CI, 0.69-0.89]; P<0.001; CKD 5: OR, 0.72 [95% CI, 0.49-1.06]; P=0.096; end-stage renal disease: OR, 0.51 [95% CI, 0.46-0.56]; P<0.001) and 6-month mortality. Invasive management was associated with higher in-hospital postprocedural complications but no difference in postdischarge safety outcomes. Invasive management was associated with a lower hazard of major adverse cardiovascular events at 6 months in all CKD groups compared with medical management. Conclusions Invasive management was associated with lower mortality and major adverse cardiovascular events but minimal increased in-hospital complications in patients with NSTEMI-CKD compared with medical management, suggesting patients with NSTEMI-CKD should be offered invasive management.

Project description:ImportanceChallenges to improving ST-segment elevation myocardial infarction (STEMI) care are formidable in low- to middle-income countries because of several system-level factors.ObjectiveTo examine access to reperfusion and percutaneous coronary intervention (PCI) during STEMI using a hub-and-spoke model.Design, setting, and participantsThis multicenter, prospective, observational study of a quality improvement program studied 2420 patients 20 years or older with symptoms or signs consistent with STEMI at primary care clinics, small hospitals, and PCI hospitals in the southern state of Tamil Nadu in India. Data were collected from the 4 clusters before implementation of the program (preimplementation data). We required a minimum of 12 weeks for the preimplementation data with the period extending from August 7, 2012, through January 5, 2013. The program was then implemented in a sequential manner across the 4 clusters, and data were collected in the same manner (postimplementation data) from June 12, 2013, through June 24, 2014, for a mean 32-week period.ExposuresCreation of an integrated, regional quality improvement program that linked the 35 spoke health care centers to the 4 large PCI hub hospitals and leveraged recent developments in public health insurance schemes, emergency medical services, and health information technology.Main outcomes and measuresPrimary outcomes focused on the proportion of patients undergoing reperfusion, timely reperfusion, and postfibrinolysis angiography and PCI. Secondary outcomes were in-hospital and 1-year mortality.ResultsA total of 2420 patients with STEMI (2034 men [84.0%] and 386 women [16.0%]; mean [SD] age, 54.7 [12.2] years) (898 in the preimplementation phase and 1522 in the postimplementation phase) were enrolled, with 1053 patients (43.5%) from the spoke health care centers. Missing data were common for systolic blood pressure (213 [8.8%]), heart rate (223 [9.2%]), and anterior MI location (279 [11.5%]). Overall reperfusion use and times to reperfusion were similar (795 [88.5%] vs 1372 [90.1%]; P = .21). Coronary angiography (314 [35.0%] vs 925 [60.8%]; P < .001) and PCI (265 [29.5%] vs 707 [46.5%]; P < .001) were more commonly performed during the postimplementation phase. In-hospital mortality was not different (52 [5.8%] vs 85 [5.6%]; P = .83), but 1-year mortality was lower in the postimplementation phase (134 [17.6%] vs 179 [14.2%]; P = .04), and this difference remained consistent after multivariable adjustment (adjusted odds ratio, 0.76; 95% CI, 0.58-0.98; P = .04).Conclusions and relevanceA hub-and-spoke model in South India improved STEMI care through greater use of PCI and may improve 1-year mortality. This model may serve as an example for developing STEMI systems of care in other low- to middle-income countries.

Project description:AimAmerican and European associations of cardiology published specific guidelines about recommended drugs for secondary prevention in ST-segment elevation myocardial infarction (STEMI) patients. Our aim was to assess whether drug prescription for STEMI patients was in accordance with the guidelines at discharge and after 1 year.MethodWe used data of 361 patients admitted for STEMI in a tertiary hospital in Switzerland from 2014 to 2016. We assessed the adequacy of prescription of recommended drugs at two time points: discharge and after 1 year. Medications assessed were aspirin, P2Y12 inhibitors, statin, angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin receptor blockers (ARBs) and ?-blockers. We took into account several criteria like statin dosage (low versus high intensity) and presence of contraindication for consideration of optimal therapy. Predictors of incomplete prescription of guideline medications were then assessed with multivariate logistic regression models.ResultsFrom discharge (n?=?358) to 1-year follow-up (n?=?303), rate of optimal prescription was reduced from 98.6 to 91.7% for aspirin, from 93.9 to 79.1% for P2Y12 inhibitors, from 83.8 to 65.7% for statins, from 98.6 to 95.6% for ACEIs/ARBs, and from 97.1 to 96.9% for ?-blockers. Predictors of incomplete prescription of guideline medications at discharge were female sex (odds ratio [OR] 2.54, p?=?0.007), active or former smoker status (OR 2.29, p?=?0.017), multivessel disease (OR 2.07, p?=?0.022), left ventricular ejection fraction?<?40% (OR 2.49, p?=?0.008), and transfer to cardiac surgery (OR 9.66, p?=?0.018). At 1 year, age?>?65 (OR 1.92, p?=?0.036) remained the only significant predictor.ConclusionThe present study showed a high prescription rate of guideline-recommended medications in a referral center for primary percutaneous coronary intervention. At discharge, women and co-morbid patients were at the highest risk of incomplete prescription of guideline medications, whereas long-term prescription was suboptimal for elderly. A drug lacking at time of discharge was rarely introduced within the year, which underscores the paramount importance of optimal prescription at time of discharge. Strategies like implementing a standardized prescription could reduce the proportion of suboptimal prescription. It could therefore be one way to improve the long-term quality of care of our patients to the highest level. This study used local data from AMIS Plus-National Registry of Acute Myocardial Infarction in Switzerland (NCT01305785).
