Long-term risk factor management and adverse events in patients with early-onset myocardial infarction-a "real-world" study.

BACKGROUND: International guidelines emphasize the importance of preventive efforts after early-onset myocardial infarction (EOMI); however, data on "real-world" long-term risk factor management and adverse event rates in this special patient group is scarce. METHODS: In this German registry study, 301 patients with MI aged ≤ 45 years were investigated. Risk factor control was assessed at the time of index MI and after 1 year. Major adverse cardiac and cerebrovascular events (MACCE) and its predictors were analyzed during long-term follow-up (median duration 49 months). RESULTS: A majority of patients with EOMI presented with insufficient risk factor control, even during 1-year follow-up. After 1-year 42% of patients were persistent smokers; 74% were physically inactive. The rate of obesity increased significantly from index MI (41%) to 1-year follow-up (46%, p = 0.03) as well as the rate of dysglycemia (index MI: 40%; 1-year follow-up: 51%, p < 0.01) and diabetes mellitus (index MI: 20%; 1-year follow-up: 24%, p < 0.01). 66% of the patients with diabetes mellitus had unsatisfactory HbA1c after 1 year; 69% of the patients did not attain guideline-recommended lipid targets. The rate of MACCE during long-term follow-up was 20% (incidence rate 0.05 per person-year). In a multivariable analysis smoking (HR 2.2, HR 1.3-3.7, p < 0.01) and physical inactivity (HR 2.8, HR 1.2-6.7, p = 0.02) were significant predictors for the occurrence of MACCE. CONCLUSION: Insufficient long-term risk factor control was common in patients with EOMI and was associated with an elevated rate of MACCE. The study reveals that better strategies for prevention in young patients are crucially needed.

Impact of educational attainment on preventive efforts after myocardial infarction: results of the IPP and NET-IPP trials.

AIMS: Educational attainment might impact secondary prevention after myocardial infarction (MI). The purpose of the present study was to compare the rate of risk factors and the efficacy of an intensive prevention program (IPP), performed by prevention assistants and supervised by physicians, in patients with MI and different levels of education. METHODS: In this post hoc analysis of the multicenter IPP and NET-IPP trials, patients with MI were stratified into two groups according to educational attainment: no "Abitur" (no A) vs. "Abitur" or university degree (AUD). The groups were compared at the time of index MI and after 12-month IPP vs. usual care. RESULTS: Out of n = 462 patients with MI, 76.0% had no A and 24.0% had AUD. At the time of index, MI rates of obesity (OR 2.4; 95%CI 1.4-4.0), smoking (OR 2.2, 95%CI 1.4-3.6), and physical inactivity (OR 1.6; 95%CI 1.0-2.5) were significantly elevated in patients with no A. At 12 months after index MI, larger improvements of the risk factors smoking and physical inactivity were observed in patients with IPP and no A than in patients with IPP and AUD or with usual care. LDL cholesterol levels were reduced by IPP compared to usual care, with no difference between no A vs. AUD. A matched-pair analysis revealed that high baseline risk was an important reason for the large risk factor reductions in patients with IPP and no A. CONCLUSION: The study demonstrates that patients with MI and lower educational level have an increased rate of lifestyle-related risk factors and a 12-month IPP, which is primarily performed by non-physician prevention assistants, is effective to improve prevention in this high-risk cohort.

Impact of COVID-19 Pandemic on Presentation and Outcome of Consecutive Patients Admitted to Hospital Due to ST-Elevation Myocardial Infarction.

Impact of COVID-19 pandemic and pandemic-related social restrictions on clinical course of patients treated for acute ST-elevation myocardial infarction (STEMI) is unclear. In the present study presentation and outcome of patients with STEMI in the year 2020 were compared with the years before in a German registry that includes all patients hospitalized for acute STEMI in a region with approximately 1 million inhabitants. In the year 2020 726 patients with STEMI were registered compared with 10.226 patients in the years 2006 to 2019 (730 ± 57 patients per year). No significant differences were observed between the groups regarding age, gender and medical history of patients. However, in the year 2020 a significantly higher rate of patients admitted with cardiogenic shock (21.9% vs 14.2%, p <0.01) and out-of-hospital cardiac arrest (OHCA) (14.3% vs 11.1%, p <0.01) was observed. The rate of patients with subacute myocardial infarction (14.3% vs 11.6%, p <0.05) was elevated in 2020. Hospital mortality increased by 52% from the years 2006 to 2019 (8.4%) to the year 2020 (12.8%, p <0.01). Only 4 patients (0.6%) with STEMI in the year 2020 had SARS-CoV-2 infection, none of those died in-hospital. In conclusion, in the year 2020 a highly significant increase of STEMI-patients admitted to hospital with advanced infarction and poor prognosis was observed. As the structure of the emergency network to treat patients with STEMI was unchanged during the study period, the most obvious reason for these changes was COVID-19 pandemic-related lockdown and the fear of many people to contact medical staff during the pandemic.

Influence of the ratio of mean arterial pressure to right atrial pressure on outcome after successful percutaneous edge-to-edge repair for severe mitral valve regurgitation.

BACKGROUND: It is important to identify further predictors of outcome after successful transcatheter mitral valve repair (TMVR), as optimal patient selection remains difficult. OBJECTIVE: The study investigates the prognostic benefit of the mean arterial pressure (MAP) to right atrial pressure (RAP) ratio (MAP/RAP ratio) after successful TMVR in patients with congestive heart failure (CHF) and severe mitral regurgitation (MR). METHOD: Patients with CHF and severe MR were enrolled after successful TMVR (MR ≤ 2+ at discharge). The primary endpoint was a composite of all-cause mortality or hospitalisation for heart failure. The median follow-up time was 16 ± 9 months. Receiver Operating Characteristic (ROC) analysis was applied to assess the discriminatory power of the MAP/RAP ratio. The predictive value of the MAP/RAP ratio threshold was investigated using a Kaplan-Meier analysis. Multivariable logistic regression analysis was conducted to evaluate independent risk factors for the combined primary endpoint. RESULTS: 145 patients (median age 76 [69-80 years], 60.3% male) were included. ROC curve analysis showed that MAP/RAP ratio was associated with an area under the curve of 0.62 (95% confidence interval (CI) 0.53-0.71; p = 0.01). A MAP/RAP ratio threshold of 7.13 was associated with 67.4% sensitivity and 57.0% specificity for the combined primary endpoint. Event-free survival was significantly lower in the MAP/RAP ratio < 7.13 group compared to those with MAP/RAP ratio ≥ 7.13 (62.2% versus 39.4%; log-rank p = 0.022). In logistic regression analysis MAP/RAP ratio was an independent predictor for the combined primary endpoint (odds ratio 0.75; 95% CI 0.62-0.90; p = 0.002). CONCLUSIONS: The MAP/RAP ratio is associated with an unfavorable outcome in patients undergoing successful TMVR. Therefore, this new index could improve prognostic assessment of TMVR candidates.
