- AIMS: To assess low-density lipoprotein cholesterol (LDL-C) treatment target attainment among myocardial infarction (MI) patients according to the ESC/EAS dyslipidaemia guidelines from 2011 (LDL-C <1.8 mmol/L or ≥ 50% LDL-C reduction) and 2016 (LDL-C <1.8 mmol/L and ≥50% LDL-C reduction).METHODS AND RESULTS: Using nationwide registers, we identified 44,890 patients aged 21-74 admitted for MI, 2013-2017. We included those attending follow-up visits at 6-10 weeks (n = 25,466) and 12-14 months (n = 17,117) after the event. Most patients received high-intensity statin monotherapy (84.3% [6-10 weeks] and 69.0% [12-14 months]) or statins with ezetimibe (2.7% and 10.2%). The proportion of patients attaining the 2011 LDL-C target was 63.8% (6-10 weeks) and 63.5% (12-14 months). The corresponding numbers for the 2016 LDL-C target was 31.6% (6-10 weeks) and 31.5% (12-14 months). At the 6-10-week follow-up, 37% of those not attaining the 2011 LDL-C target and 48% of those not attaining the 2016 target had an LDL-C level that was ≥0.5 mmol/L from the target. When comparing LDL-C measurements performed before vs. after the release of the 2016 guidelines, attainment of the 2016 LDL-C target increased from 30.2% to 35.0% (6-10 weeks) and from 27.6% to 37.6% (12-14 months).CONCLUSIONS: In a nationwide register, one out of three patients with a recent MI had not attained the LDL-C target of the 2011 ESC/EAS guidelines and two out of three patients had not attained the LDL-C target of the 2016 guidelines.

- BackgroundThe incidence of atherosclerotic cardiovascular disease increases with levels of low-density lipoprotein cholesterol (LDL-C). Yet, a paradox may exist where lower LDL-C levels at myocardial infarction (MI) are associated with poorer prognoses.ObjectiveTo assess the association between LDL-C levels at MI with risk factor burden and cause-specific outcomes.MethodsStatin-naive patients hospitalized for a first MI and registered in SWEDEHEART were included. Data were linked to Swedish registers. Primary outcomes were all-cause mortality and nonfatal MI. Associations between LDL-C and outcomes were assessed using adjusted proportional hazards models.ResultsAmong 63,168 patients (median age, 66 years), the median LDL-C level was 3.0 mmol/L (interquartile range 2.4–3.6). Patient age and comorbidities increased as LDL-C decreased. During a median follow-up of 4.5 years, 10,236 patients died, and 4973 had nonfatal MI. Patients with the highest LDL-C had a lower risk of mortality (hazard ratio [HR] 0.75; 95% confidence interval [CI] 0.71–0.80). The risk of hospitalization for pneumonia, hip fracture, chronic obstructive pulmonary disease, and new cancer diagnosis was lower with higher LDL-C (HR range, 0.40–0.81). Patients with the highest LDL-C had a greater risk of recurrent MI (HR 1.16; 95% CI 1.07–1.26).ConclusionsPatients with the highest LDL-C levels at MI had the lowest incidence of mortality and morbidity. This seems to reflect lower age at MI, less underlying morbidities, paired with the modifiability of LDL-C. However, supporting the causal association between LDL-C and ischemic heart disease, elevated LDL-C was simultaneously associated with an increased risk of nonfatal MI.

- Aims: Clinical trials have demonstrated that a reduction in low-density lipoprotein cholesterol (LDL-C) reduces cardiovascular (CV) events. This has, however, not yet been shown in a real-world setting. We aimed to investigate the association between LDL-C changes and statin intensity with prognosis after a myocardial infarction (MI). Methods and results: Patients admitted with MI were followed for mortality and major CV events. Changes in LDL-C between the MI and a 6-to 10-week follow-up visit were analysed. The associations between quartiles of LDL-C change and statin intensity with outcomes were assessed using adjusted Cox regression analyses. A total of 40 607 patients were followed for a median of 3.78 years. The median change in LDL-C was a 1.20 mmol/L reduction. Patients with larger LDL-C reduction (1.85 mmol/L, 75th percentile) compared with a smaller reduction (0.36 mmol/L, 25th percentile) had lower hazard ratios (HR) for all outcomes (95% confidence interval): composite of CV mortality, MI, and ischaemic stroke 0.77 (0.70-0.84); all-cause mortality 0.71 (0.63-0.80); CV mortality 0.68 (0.57-0.81); MI 0.81 (0.73-0.91); ischaemic stroke 0.76 (0.62-0.93); heart failure hospitalization 0.73 (0.63-0.85), and coronary artery revascularization 0.86 (0.79-0.94). Patients with ≥50% LDL-C reduction using high-intensity statins at discharge had a lower incidence of all outcomes compared with those using a lower intensity statin. Conclusions: Larger early LDL-C reduction and more intensive statin therapy after MI were associated with a reduced hazard of all CV outcomes and all-cause mortality. This supports clinical trial data suggesting that earlier lowering of LDL-C after an MI confers the greatest benefit.
