Determination of BNP 24-96 hours after a NSTE-ACS improved discrimination of patients at risk for mortality during admission and follow up.

The implementation of the major cardiovascular adverse events allowed to increase the rate and the percentage of women with ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention and reducing total ischemic time.

Chest trauma is a major health problem with a high mortality. Myocardial infarction secondary to coronary dissection following blunt chest trauma is a rare entity. We describe the case of an inferior MI following blunt chest trauma. A 61-year-old male without any relevant medical history was transported to a hospital after a low-velocity motorcycle accident. The patient was asymptomatic before the accident. The patient developed severe chest pain and an ECG revealed inferior ST segment elevation. After ruling out aortic dissection with angio-CT, a coronary angiograph depicted a proximal occlusion of the right coronary artery. After thrombectomy, a typical image of coronary artery dissection was observed; the image persisted after several runs of thrombectomy and for that reason a bare metal stent was implanted with a good final angiographic result. Five days after admission the patient was discharged home. Cardiac contusion is not uncommon; however acute myocardial infarction is a rare complication of blunt chest trauma. Thorough evaluation with clinical suspicion can lead to optimal medical care.

Background Age-specific and gender-specific reference values for left ventricular (LV) and right ventricle volumes are available. The prognostic implications of the ratio between these volumes in heart failure and preserved ejection fraction (HFpEF) have never been evaluated. Methods We examined all HFpEF outpatients undergoing a cardiac magnetic resonance from 2011 to 2021. The left-to-right ventricular volume ratio (LRVR) was defined as the ratio between the LV and right ventricle end-diastolic volume indexes (LVEDVi/RVEDVi). Results Among 159 patients [median age 58 years (interquartile range 49–69), 64% men, LV ejection fraction 60% (54–70%)] the median LRVR was 1.21 (1.07–1.40). Over 3.5 years (1.5–5.0), 23 patients (15%) experienced all-cause death or heart failure hospitalization, and 22 (14%) cardiovascular death or heart failure hospitalization. The risk of all-cause death or heart failure hospitalization increased with an LRVR less than 1.0 or at least 1.4. An LRVR less than 1.0 was associated with a higher risk of all-cause death or heart failure hospitalization [hazard ratio 5.95, 95% confidence interval (CI) 1.67–21.28; P = 0.006] and cardiovascular death or heart failure hospitalization (hazard ratio 5.68, 95% CI 1.58–20.35; P = 0.008) as compared with LRVR 1.0–1.3. Furthermore, an LRVR at least 1.4 was associated with a higher risk of all-cause death or heart failure hospitalization (hazard ratio 4.10, 95% CI 1.58–10.61; P = 0.004) and cardiovascular death or heart failure hospitalization (hazard ratio 3.71, 95% CI 1.41–9.79; P = 0.008) as compared with LRVR 1.0–1.3. These results were confirmed in patients without dilation of either ventricle. Conclusion LRVR values less than 1.0 or at least 1.4 are associated with worse outcomes in HFpEF. LRVR may become a valuable tool for risk prediction in HFpEF.
