Mortality, Cardiovascular, and Medication Outcomes in Patients With Myocardial Infarction and Underweight in a Meta-Analysis of 6.3 Million Patients. Am J Cardiol 2023; 196:1-10. [PMID: 37023510 DOI: 10.1016/j.amjcard.2023.02.023] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 02/16/2023] [Accepted: 02/28/2023] [Indexed: 04/08/2023]
Abstract
Although most of the current evidence on myocardial infarction focuses on obesity, there is growing evidence that patients who are underweight have unfavorable prognosis. This study aimed to explore the prevalence, clinical characteristics, and prognosis of this population at risk. Embase and Medline were searched for studies reporting outcomes in populations who were underweight with myocardial infarction. Underweight and normal weight were defined according to the World Health Organization criteria. A single-arm meta-analysis of proportions was used to estimate the prevalence of underweight in patients with myocardial infarction, whereas a meta-analysis of proportions was used to estimate the odds ratio of all-cause mortality, medications prescribed, and cardiovascular outcomes. Twenty-one studies involving 6,368,225 patients were included, of whom 47,866 were underweight. The prevalence of underweight in patients with myocardial infarction was 2.96% (95% confidence interval 1.96% to 4.47%). Despite having fewer classical cardiovascular risk factors, patients who were underweight had 66% greater hazard for mortality (hazard ratio 1.66, 95% confidence interval 1.44 to 1.92, p <0.0001). The mortality of patients who were underweight increased from 14.1% at 30 days to 52.6% at 5 years. Nevertheless, they were less likely to receive guideline-directed medical therapy. Relative to subjects with normal weight, Asian populations who were underweight had greater mortality risks than those of their Caucasian counterparts (p = 0.0062). In conclusion, in patients with myocardial infarction, those who were underweight tend to have poorer prognostic outcomes. A lower body mass index is an independent predictor of mortality, which calls for global efforts in addressing this modifiable risk factor in clinical practice guidelines.

Abstract
OBJECTIVE This study aimed to investigate the effect of intracoronary (IC) tirofiban compared to intravenously administered tirofiban in STEMI patients treated with PPCI. METHODS This study included 180 STEMI patients who were underwent PPCI. Patients were randomized into an IC group (n = 90) and intravenous (IV) group (n = 90). During the procedure, the both groups were administered IC or IV injections of tirofiban, respectively, followed by an IV infusion of tirofiban for 24 hours. Changes in TIMI flow grading, TMP grade 3, Sum-STR two hours after the operation, the number of thrombus aspirations during the operation, myocardial enzyme, inflammatory factors,cardiac functional parameters, MACE and bleeding were investigated. RESULTS Following treatment, TIMI flow grading and TMP grade 3 were improved in the IC tirofiban compared to the IV group (P = 0.022 and P = 0.014, respectively). Additionally, the Sum-STR two hours after operation, the incidence of MACEs, levels of AST, CRP, ESR, and TNI in the IC group was improved, compared with the IV group (all P < 0.05). Furthermore. Cardiac function including CO and LVEF were significantly improved in the IC group 6 months after discharge. CONCLUSION This study found that IC administration of tirofiban in patients with STEMI who underwent PPCI improved TIMI, TMP flow and cardiac function 6 months after discharge, and reduced CRP, ESR, and TNI. However, the incidence of bleeding between the two groups was comparable. These findings suggest that IC administration should be applied in certain acute STEMI patients.

Abstract
AIMS The relationship between low body mass index (BMI) and prognostic factors for patients with coronary artery disease, commonly observed in elderly individuals in Japan, is important. Few studies have evaluated the prognosis for patients with low BMI after percutaneous coronary intervention (PCI). Using a multivariable-adjusted model and data from a prospective cohort registry, we analyzed the risk associated with low BMI for patients after PCI. METHODS This prospective, multicenter registry included 5965 consecutive patients with coronary artery disease who underwent successful PCI. The patients were followed-up clinically for up to 3 years or until the occurrence of major adverse cardiac events. The primary endpoint was all-cause death and nonfatal myocardial infarction composite. RESULTS Primary events occurred in 639 (10.7%) patients during the follow-up period. A risk analysis of the primary endpoint adjusted for the multivariable model showed a significant increase in risk for elderly individuals, underweight individuals [HR 1.43 (95% confidence interval (CI), 1.10-1.85), P<0.001], those with diabetes mellitus (DM), peripheral artery disease, low left ventricular ejection fraction or acute coronary syndrome (ACS), and smokers. A stratified adjusted risk analysis based on BMI levels showed that the risk associated with underweight status was significantly pronounced for male patients, those aged 60-74 years, and those with DM or ACS. CONCLUSION Underweight patients with several risk factors significantly increased risk after PCI. Furthermore, the risk associated with low BMI was significantly more pronounced for men, individuals aged 60-74 years, and patients with DM or ACS.

Front Cardiovasc Med 2021; 8:765153.

Abstract
Background: Body mass index (BMI) is a critical determinant of mortality after acute myocardial infarction (AMI), and higher BMI is associated with survival benefit in patients with renal impairment. However, there are no studies investigating the interactive effects of BMI and renal function on mortality risk after AMI occurrence. Methods: We enrolled 12,647 AMI patients from Korea Acute Myocardial Infarction Registry between November 2011 and December 2015. Patients were categorized based on estimated Glomerular Filtration Rate (eGFR) and BMI. The primary endpoint was all-cause mortality after AMI treatment. Results: Within each renal function category, the absolute mortality rate was decreased in patients with higher BMI. However, the adjusted hazard ratio (HR) of all-cause mortality for higher BMI was decreased as renal function worsened [adjusted HR (95% confidence interval) at BMI ≥ 25 kg/m2: 0.63 (0.41-0.99), 0.76 (0.59-0.97), and 0.84 (0.65-1.08) for patients with eGFR ≥ 90, 90-45, and <45 mL/min/1.73 m2, respectively]. There was a significant interaction between BMI and renal function (P for interaction = 0.010). The protective effect of higher BMI was preserved against non-cardiac death and it was also decreased with lowering eGFR in competing risks models [adjusted HR at BMI ≥25 kg/m2: 0.38 (0.18-0.83), 0.76 (0.59-0.97), and 0.84 (0.65-1.08) for patients with eGFR ≥ 90, 90-45, and <45 mL/min/1.73 m2, respectively; P for interaction = 0.03]. However, renal function did not significantly affect the association between BMI and risk of cardiac death (P for interaction = 0.20). Conclusions: The effect of BMI on the mortality risk after AMI was dependent on renal function. The association between greater BMI and survival benefit was weakened as renal function was decreased. In addition, the negative effect of renal function on the BMI - mortality association was pronounced in the non-cardiac death.

Abstract
A 61-year-old woman suffered chest pain and was admitted to a nearby hospital emergency department. She was diagnosed with acute myocardial infarction probably due to thromboembolism in the left anterior descending coronary artery and aspiration thrombectomy was performed. Afterwards, she developed refractory heart failure with severe global left ventricular dysfunction and was transferred to our hospital. An 18F-FDG-PET/CT scan revealed abnormal 18F-FDG uptake in non-infarcted regions of the left ventricle. Non-caseating granulomas were detected by biopsy from a skin eruption. She was diagnosed with cardiac sarcoidosis. In cases of refractory heart failure which cannot be explained only by myocardial infarction, evaluation of other undiagnosed cardiomyopathies is important for optimal management.
