Association of admission hyperglycemia and all-cause mortality in acute myocardial infarction with percutaneous coronary intervention: A dose-response meta-analysis.

ABSTRACT:

Objective

The aim of this study is to evaluate the associations between admission hyperglycemia and the risk of all-cause mortality in patients with acute myocardial infarction (AMI) with or without diabetes, to find optimal admission glucose intervention cut-offs, and to clarify the shape of the dose-response relations.

Methods

Medline/PubMed and EMBASE were searched from inception to 1 April 2022. Cohort studies reporting estimates of all-cause mortality risk in patients with admission hyperglycemia with AMI were included. The outcomes of interest include mortality and major adverse cardiac events (MACEs). A random effect dose-response meta-analysis was conducted to access linear trend estimations. A one-stage linear mixed effect meta-analysis was used for estimating dose-response curves. Relative risks and 95% confidence intervals were pooled using a random-effects model.

Results

Of 1,222 studies screened, 47 full texts were fully reviewed for eligibility. The final analyses consisted of 23 cohort studies with 47,177 participants. In short-term follow-up, admission hyperglycemia was associated with an increased risk of all-cause mortality (relative risk: 3.12, 95% confidence interval 2.42-4.02) and MACEs (2.34, 1.77-3.09). In long-term follow-up, admission hyperglycemia was associated with an increased risk of all-cause mortality (1.97, 1.61-2.41) and MACEs (1.95, 1.21-3.14). A linear dose-response association was found between admission hyperglycemia and the risk of all-cause mortality in patients with or without diabetes.

Conclusion

Admission hyperglycemia was significantly associated with higher all-cause mortality risk and rates of MACEs. However, the association between admission hyperglycemia and long-term mortality risk needs to be determined with caution. Compared with current guidelines recommendations, a lower intervention cut-off and more stringent targets for admission hyperglycemia may be appropriate.

Project description:BackgroundAdmission hyperglycemia (AH) is a common finding in patients with acute coronary syndrome and has been reported to be associated with increased morbidity and mortality. Prior studies suggest that AH could be associated with reperfusion failure. We conducted a systematic review and meta-analysis to explore an association between AH and risk of reperfusion failure in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI).MethodsTwo investigators searched the databases of MEDLINE and EMBASE from inception to February 2021. Study eligibility was independently determined by two investigators and needed to demonstrate association of AH and rate of reperfusion failure, or sufficient raw data to calculate the effect size. Participants were classified into two groups corresponding to their level of admission hyperglycemia. Group 1 was defined as an AH of ≥120-150 mg/dl, and group 2 as ≥150-200 mg/dl. Data from each study were combined using the random-effects model, the generic inverse-variance method of Der Simonian and Laird. The heterogeneity of effect size was quantified using the I2 statistic. A sensitivity analysis was performed by omitting one study at a time. Publication bias was assessed using a funnel plot and the Egger's test. All data analyses were performed using STATA SE version 14.2.ResultsA total of ten studies from 2008 to 2019 met eligibility criteria and were included in the final analysis. We found that AH is associated with increased risk of reperfusion failure in both group 1 (pooled OR=1.78, 95% CI: 1.35-2.33, I2=63.2%, P<0.001) and group 2 (pooled OR=1.44, 95% CI: 1.14-1.82, I2=57.1%, P<0.001). Sensitivity analysis showed that none of the results were significantly altered after removing one study at a time. In subgroup analysis of non-diabetic patients, we found that AH is also associated with increased risk of reperfusion failure in both group 1 (pooled OR=1.81, 95% CI: 1.29-2.54, P<0.001) and group 2 (pooled OR=1.61, 95% CI: 1.17-2.21, P<0.001). We did not perform a funnel plot or Egger's test as the number of available outcomes was insufficient to reject the assumption of funnel plot asymmetry.ConclusionsOur systematic review and meta-analysis demonstrated that AH is associated with increased risk of reperfusion failure in STEMI patients undergoing pPCI, in the non-diabetic population.

Project description:Background:High survival rates are commonly reported following primary percutaneous coronary intervention for ST-elevation myocardial infarction, with most contemporary studies reporting overall survival.Aims:The aim of this study was to describe survival following primary percutaneous coronary intervention for ST-elevation myocardial infarction corrected for non-cardiovascular deaths by reporting relative survival and investigate clinically significant factors associated with poor long-term outcomes.Methods and results:Using the prospective UK Percutaneous Coronary Intervention registry, primary percutaneous coronary intervention cases ( n=88,188; 2005-2013) were matched to mortality data for the UK populace. Crude five-year relative survival was 87.1% for the patients undergoing primary percutaneous coronary intervention and 94.7% for patients <55 years. Increasing age was associated with excess mortality up to four years following primary percutaneous coronary intervention (56-65 years: excess mortality rate ratio 1.61, 95% confidence interval 1.46-1.79; 66-75 years: 2.49, 2.26-2.75; >75 years: 4.69, 4.27-5.16). After four years, there was no excess mortality for ages 56-65 years (excess mortality rate ratio 1.27, 0.95-1.70), but persisting excess mortality for older groups (66-75 years: excess mortality rate ratio 1.72, 1.30-2.27; >75 years: 1.66, 1.15-2.41). Excess mortality was associated with cardiogenic shock (excess mortality rate ratio 6.10, 5.72-6.50), renal failure (2.52, 2.27-2.81), left main stem stenosis (1.67, 1.54-1.81), diabetes (1.58, 1.47-1.69), previous myocardial infarction (1.52, 1.40-1.65) and female sex (1.33, 1.26-1.41); whereas stent deployment (0.46, 0.42-0.50) especially drug eluting stents (0.27, 0.45-0.55), radial access (0.70, 0.63-0.71) and previous percutaneous coronary intervention (0.67, 0.60-0.75) were protective.Conclusions:Following primary percutaneous coronary intervention for ST-elevation myocardial infarction, long-term cardiovascular survival is excellent. Failure to account for non-cardiovascular death may result in an underestimation of the efficacy of primary percutaneous coronary intervention.

Project description:Background: The coronary atherosclerotic burden in patients with ST-segment elevation myocardial infarction (STEMI) has been identified as the main predictor of prognosis. However, the association of lipoprotein(a) [Lp(a)], a well-established proatherogenic factor, with atherosclerotic burden in patients with STEMI is unclear. Methods: In total, 1,359 patients who underwent percutaneous coronary intervention (PCI) for STEMI were included in analyses. Three prespecified models with adjustment for demographic parameters and risk factors were evaluated. Generalized additive models and restricted cubic spline analyses were used to assess the relationships of Lp(a) with Gensini scores and the no-reflow phenomenon. Kaplan-Meier curves were generated to explore the predictive value of Lp(a) for long-term all-cause mortality. Furthermore, mRNA expression levels of LPA in different groups were compared using the GEO database. Results: Patients in the highest tertile according to Lp(a) levels had an increased incidence of heart failure during hospitalization. Furthermore, patients with high levels of Lp(a) (>19.1 mg/dL) had sharply increased risks for a higher Gensini score (P for trend = 0.03) and no-reflow (P for trend = 0.002) after adjustment for demographic parameters and risk factors. During a median follow-up of 930 days, 132 deaths (9.95%) were registered. Patients with high levels of Lp(a) (>19.1 mg/dL) had the worst long-term prognosis (P for trend < 0.0001). In a subgroup analysis, patients with higher Lp(a) still had the highest all-cause mortality. Additionally, the mRNA expression levels of LPA in patients with STEMI with lower cardiac function were higher than those in other groups (P = 0.003). A higher coronary atherosclerotic burden was correlated with higher LPA expression (P = 0.01). Conclusion: This study provides the first evidence that Lp(a) (at both the protein and mRNA levels) is independently associated with coronary atherosclerotic lesions and prognosis in patients with STEMI treated with PCI.
