Serum zinc concentration in patients with acute myocardial infarction in percutaneous coronary intervention era.

ABSTRACT:

Introduction

There were few studies that investigated the association between serum zinc concentration and acute myocardial infarction (AMI) in percutaneous coronary intervention era.

Objective

We assessed the relationships between serum zinc concentration, complications, and prognosis in AMI patients after primary percutaneous coronary intervention.

Methods

We conducted a single-center, prospective, observational study including 50 patients with AMI. We divided patients into two groups (High-zinc group and Low-zinc group) by median serum zinc concentration and compared two groups about clinical outcomes up to 1 year follow up.

Results

The mean age of patients was 66.2 ± 11.8 years old. Patients in the Low-zinc group had ST-segment elevation more frequently than those in the High-zinc group (96.0% vs. 72.0%, P = 0.02). All-cause mortality at 1 year was similar in both groups (P (log-rank) = 0.33). However, the lengths of hospital stay and in coronary care unit were longer in patients in the Low-zinc group than in those in the High-zinc group (15.6 ± 9.2 days vs. 11.9 ± 2.9 days, P = 0.06; 3.9 ± 2.8 days vs. 2.3 ± 0.8 days, P = 0.01). Multivariate regression analysis showed that low serum zinc concentration was associated with the use of cardiac or respiratory assist devices (adjusted odds ratio, 17.79; 95% CI 1.123 to 1216.5; P = 0.04).

Conclusions

Although there was no significance difference in mortality in Low-zinc and High-zinc groups, low serum zinc concentration was associated with longer stay in the coronary care unit, and was one of the independent predictors for the use of cardiac or respiratory assist devices.

Project description:BackgroundPrimary percutaneous coronary intervention (PPCI) has been widely recognized as the preferred treatment for ST-segment-elevation myocardial infarction (STEMI). However, substantial numbers of STEMI patients cannot receive timely PPCI. Early fibrinolysis followed by routine percutaneous coronary intervention (FPCI) has been proposed as an effective and safe alternative for eligible patients. To date, few studies have compared FPCI with PPCI in terms of microvascular reperfusion. This study aimed to evaluate the microvascular function of FPCI and PPCI.MethodsSTEMI patients at the Peking University First Hospital and Miyun Hospital were enrolled in this retrospective study between January 2015 to December 2020. Microvascular function documented by the coronary angiography-derived index of microvascular resistance (caIMR) was measured at the final angiogram after revascularization. The primary end point was the caIMR of the culprit vessels. The secondary end points were in-hospital and follow-up major adverse cardiovascular events (MACE), including cardiovascular death, non-fatal recurrent myocardial infarction, target-vessel revascularization (TVR), and non-fatal stroke/transient ischemic attacks (TIA). Details of the adverse clinical events were obtained from telephone interviews and electronic medical record systems until January 2022.ResultsIn total, 496 STEMI patients were enrolled in this cross-sectional retrospective study. Of these patients, 81 underwent FPCI, and 415 underwent PPCI. At the baseline, the PPCI patients had a higher-risk profile than the FPCI patients. The time from symptom onset to reperfusion therapy was significantly shorter in the FPCI group than the PPCI group (median 3.0 vs. 4.5 hours; P<0.001). The caIMR was significantly lower in the FPCI group than the PPCI group (median 20.34 vs. 40.33; P<0.001). The median follow-up duration was 4.1 years. During the follow-up period, the rate of MACE was lower in the FPCI group than the PPCI group [7 (10.1%) vs. 82 (20.8%), P=0.048]. After propensity score matching to adjust for the imbalances at the baseline, the caIMR remained significant and the clinical outcomes did not differ significantly between the two groups.ConclusionsIn eligible STEMI patients, clinically successful FPCI may be associated with better microvascular reperfusion and comparable clinical outcomes as compared with PPCI.

Project description:ImportanceDespite a rapid increase in percutaneous coronary intervention (PCI) procedures in China, little is known about patient-reported health status before and after PCI in patients without acute myocardial infarction (AMI).ObjectiveTo describe self-perceived angina-specific health status prior to PCI and 1 year after the procedure in patients without AMI in China.Design, setting, and participantsThe China Patient-Centered Evaluative Assessment of Cardiac Events (PEACE) Prospective Study of PCI was a population-based, multicenter cohort study of a consecutive sample of 1611 patients without AMI undergoing elective PCI. Participants were enrolled from 40 hospitals in 18 provinces in China from December 2012 to August 2014. Participants were eligible if they underwent PCI for stable and unstable angina and did not have AMI. Participants were excluded if they died in hospital, withdrew from follow-up, or had missing data on self-reported health status at baseline or at 1 year after PCI. The date of the analysis was September 15, 2018.ExposuresPercutaneous coronary intervention for ischemic heart disease.Main outcomes and measuresAngina frequency and angina-related quality of life were assessed with the Seattle Angina Questionnaire (SAQ) immediately prior to PCI and 1 year after the procedure. Either (1) an increase in the SAQ Angina Frequency score of 10 or more points or (2) an increase in the SAQ Quality-of-Life score of 10 or more points was considered to represent clinically significant improvement.ResultsOf 1611 patients, 520 (32.3%) were women; mean (SD) age was 61.3 (9.8) years. Among these patients, 443 (27.5%) had stable coronary artery disease and 1168 (72.5%) had unstable angina. One hundred fourteen of 443 patients undergoing PCI for stable coronary artery disease (25.7%) and 175 of 1168 undergoing PCI for unstable angina (15.0%) had no reported angina symptoms at the time of the procedure (SAQ Angina Frequency score = 100). Moreover, 18% of all patients (290) had minimal angina symptoms (SAQ Angina Frequency score >90) and, thus, no potential for substantial clinical improvement. Patients with smaller clinical improvements in angina symptom burden at 1 year following PCI had significantly higher baseline SAQ scores for all scales than patients with greater clinical improvement, but generally similar sociodemographic and procedural characteristics.Conclusions and relevanceIn this study, 25.7% of patients undergoing PCI for stable coronary artery disease had no reported angina symptoms at the time of the procedure. Patients with smaller clinical improvements in angina symptom burden had higher baseline SAQ scores, which highlights the importance of ascertaining impairment from angina among patients without AMI prior to performing PCI.
