Clinical characteristics and outcomes of young adults with first myocardial infarction: Results from Gulf COAST.

ABSTRACT: Introduction: Limited data exists on the risk factor profile and outcomes of young patients suffering their first acute myocardial infarction (AMI).

Methods: We examined 1562 Gulf-Arabs without prior cardiovascular disease presenting with first AMI enrolled in the Gulf COAST prospective cohort. Clinical characteristics were compared in patients ?50 years of age (young) vs. >50 years (older). Associations between age group and in-hospital adverse events (re-infarction, heart failure, cardiogenic shock, cardiac arrest, stroke, and in-hospital death) or post-discharge mortality were estimated using logistic regression.

Results: Young patients represented 26.1% (n = 407) of first AMI cases and were more likely to be men (82.8% vs. 66.5%), current smokers (49.9% vs 19.0%), obese (38.3% vs 28.0%), and have family history of premature coronary artery disease (21.4% vs 10.4%) compared with older patients (all P < 0.001). Young patients were more likely to receive ?-blockers (83.0% vs 74.4%; P < 0.001), clopidogrel (82.3% vs 76.0%; P = 0.009) and primary reperfusion therapy (85.6% vs. 75.6%; P = 0.003). Young adults had lower in-hospital death (adjusted odds ratio [aOR] = 0.37; 95%CI = 0.16-0.86) or any in-hospital adverse cardiovascular events (aOR = 0.53; 95%CI = 0.34-0.83). Young adults had lower likelihood of cumulative death at 12-month post-discharge (aOR = 0.34; 95%CI = 0.19-0.59) after adjusting for potential confounders.

Conclusion: Young patients with first AMI were more likely to be obese, smokers and have family history of premature coronary artery disease compared to older adults. Young patients were more likely to receive guideline-proven therapies and have better in-hospital and post-discharge mortality. These data highlight important age-related care gaps in patients suffering AMI for the first time.

Project description:ImportanceAn increasing proportion of people in the US hospitalized for acute myocardial infarction (AMI) are younger than 55 years, with the largest increase in young women. Effective prevention requires an understanding of risk factors associated with risk of AMI in young women compared with men.ObjectivesTo assess the sex-specific associations of demographic, clinical, and psychosocial risk factors with first AMI among adults younger than 55 years, overall, and by AMI subtype.Design, setting, and participantsThis study used a case-control design with 2264 patients with AMI, aged 18 to 55 years, from the VIRGO (Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients) study and 2264 population-based controls matched for age, sex, and race and ethnicity from the National Health and Nutrition Examination Survey from 2008 to 2012. Data were analyzed from April 2020 to November 2021.ExposuresA wide range of demographic, clinical, and psychosocial risk factors.Main outcomes and measuresOdds ratios (ORs) and population attributable fractions (PAF) for first AMI associated with demographic, clinical, and psychosocial risk factors.ResultsOf the 4528 case patients and matched controls, 3122 (68.9%) were women, and the median (IQR) age was 48 (44-52) years. Seven risk factors (diabetes [OR, 3.59 (95% CI, 2.72-4.74) in women vs 1.76 (1.19-2.60) in men], depression [OR, 3.09 (95% CI, 2.37-4.04) in women vs 1.77 (1.15-2.73) in men], hypertension [OR, 2.87 (95% CI, 2.31-3.57) in women vs 2.19 (1.65-2.90) in men], current smoking [OR, 3.28 (95% CI, 2.65-4.07) in women vs 3.28 (2.65-4.07) in men], family history of premature myocardial infarction [OR, 1.48 (95% CI, 1.17-1.88) in women vs 2.42 (1.71-3.41) in men], low household income [OR, 1.79 (95% CI, 1.28-2.50) in women vs 1.35 (0.82-2.23) in men], hypercholesterolemia [OR, 1.02 (95% CI, 0.81-1.29) in women vs 2.16 (1.49-3.15) in men]) collectively accounted for the majority of the total risk of AMI in women (83.9%) and men (85.1%). There were significant sex differences in risk factor associations: hypertension, depression, diabetes, current smoking, and family history of diabetes had stronger associations with AMI in young women, whereas hypercholesterolemia had a stronger association in young men. Risk factor profiles varied by AMI subtype, and traditional cardiovascular risk factors had higher prevalence and stronger ORs for type 1 AMI compared with other AMI subtypes.Conclusions and relevanceIn this case-control study, 7 risk factors, many potentially modifiable, accounted for 85% of the risk of first AMI in young women and men. Significant differences in risk factor profiles and risk factor associations existed by sex and by AMI subtype. These findings suggest the need for sex-specific strategies in risk factor modification and prevention of AMI in young adults. Further research is needed to improve risk assessment of AMI subtypes.

Project description:Background Stress experienced in a marriage or committed relationship may be associated with worse patient-reported outcomes after acute myocardial infarction (AMI), but little is known about this association in young adults (≤55 years) with AMI. Methods and Results We used data from VIRGO (Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients), an observational cohort study that enrolled individuals aged 18 to 55 years with AMI (2008-2012). Marital stress was self-reported 1 month after AMI using the Stockholm Marital Stress Scale (categorized as absent/mild, moderate, and severe). Outcomes were physical/mental health (Short Form-12), generic health status (EuroQol-5 Dimensions), cardiac-specific quality of life and angina (Seattle Angina Questionnaire), depressive symptoms (Patient Health Questionnaire-9), and all-cause readmission 1 year after AMI. Regression models were sequentially adjusted for baseline health, demographics (sex, age, race or ethnicity), and socioeconomic factors (education, income, employment, and insurance). Sex and marital stress interaction was also tested. Among 1593 married/partnered participants, 576 (36.2%) reported severe marital stress, which was more common in female than male participants (39.4% versus 30.4%, P=0.001). Severe marital stress was significantly associated with worse mental health (beta=-2.13, SE=0.75, P=0.004), generic health status (beta=-3.87, SE=1.46, P=0.008), cardiac-specific quality of life (beta=-6.41, SE=1.65, P<0.001), and greater odds of angina (odds ratio [OR], 1.49 [95% CI, 1.06-2.10], P=0.023) and all-cause readmissions (OR, 1.45 [95% CI, 1.04-2.00], P=0.006), after adjusting for baseline health, demographics, and socioeconomic factors. These associations were similar across sexes (P-interaction all >0.05). Conclusions The association between marital stress and worse 1-year health outcomes was statistically significant in young patients with AMI, suggesting a need for routine screening and the creation of interventions to support patients with stress recovering from an AMI.

Project description:BACKGROUND:Substance abuse is increasingly prevalent among young adults, but data on cardiovascular outcomes remain limited. OBJECTIVES:The objectives of this study were to assess the prevalence of cocaine and marijuana use in adults with their first myocardial infarction (MI) at ≤50 years and to determine its association with long-term outcomes. METHODS:The study retrospectively analyzed records of patients presenting with a type 1 MI at ≤50 years at 2 academic hospitals from 2000 to 2016. Substance abuse was determined by review of records for either patient-reported substance abuse during the week before MI or substance detection on toxicology screen. Vital status was identified by the Social Security Administration's Death Master File. Cause of death was adjudicated using electronic health records and death certificates. Cox modeling was performed for survival free from all-cause and cardiovascular death. RESULTS:A total of 2,097 patients had type 1 MI (mean age 44.0 ± 5.1 years, 19.3% female, 73% white), with median follow-up of 11.2 years (interquartile range: 7.3 to 14.2 years). Use of cocaine and/or marijuana was present in 224 (10.7%) patients; cocaine in 99 (4.7%) patients, and marijuana in 125 (6.0%). Individuals with substance use had significantly lower rates of diabetes (14.7% vs. 20.4%; p = 0.05) and hyperlipidemia (45.7% vs. 60.8%; p < 0.001), but they were significantly more likely to use tobacco (70.3% vs. 49.1%; p < 0.001). The use of cocaine and/or marijuana was associated with significantly higher cardiovascular mortality (hazard ratio: 2.22; 95% confidence interval: 1.27 to 3.70; p = 0.005) and all-cause mortality (hazard ratio: 1.99; 95% confidence interval: 1.35 to 2.97; p = 0.001) after adjusting for baseline covariates. CONCLUSIONS:Cocaine and/or marijuana use is present in 10% of patients with an MI at age ≤50 years and is associated with worse all-cause and cardiovascular mortality. These findings reinforce current recommendations for substance use screening among young adults with an MI, and they highlight the need for counseling to prevent future adverse events.
