INTRODUCTION: We sought to determine whether subclinical aortic atherosclerosis, detected noninvasively using cardiovascular magnetic resonance (CMR), predicts major adverse cardiovascular events (MACE) in adults without history or clinical manifestation of cardiovascular disease (CVD). METHODS: 318 Framingham Heart Study (FHS) Offspring cohort members (60±9 yrs, 51% women) underwent CMR in 1998–1999. Subjects were free of clinical CVD and were recruited from equal strata of age, sex and quintile of Framingham Coronary Risk score (FCRS), with double sampling of the top quintile. CMR of the descending aorta on a 1.5-T system used an ECG-triggered black-blood T2W TSE sequence with 1.03 × 0.64 × 5-mm 3 voxels, 10-mm gap. Aortic-lumen and plaque areas were hand-traced. MACE included CV death, myocardial infarction (MI), stroke or new heart failure (HF). A Cox proportional hazards model adjusted for FCRS was used to determine hazard ratio (HR) for MACE for the (within-sexes) quartile of subjects with greatest plaque burden (Q4) vs other subjects (Q1–3). Log-rank test was used to compare survival. RESULTS: CMR aortic atherosclerosis was identified in 38% of women and 41% of men. Over median 5.2-yr follow up, 38 MACE (4 deaths, 14 MIs, 12 strokes, 8 HF) occurred among 31 subjects. Greater plaque burden (Q4) was associated with 2.75-fold greater hazard of MACE (95% CI 1.33 – 5.69, p=0.007). The Figure shows Kaplan-Meier survival, log-rank p=0.0009. CONCLUSIONS: In a free-living population without history of cardiovascular disease, CMR evidence of subclinical aortic atherosclerosis was a predictor of 5-year MACE, even after adjustment for traditional cardiovascular risk factors.

INTRODUCTION: Resting left ventricular (LV) wall motion abnormalities (WMAs) are associated with significant morbidity and mortality. We hypothesized that unsuspected resting WMAs would be present in a healthy population and applied cardiovascular magnetic resonance (CMR) to characterize the prevalence of these in a free-living population. METHODS: 1794 subjects in the Framingham Heart Study Offspring Cohort (844M, 65±9 yrs) underwent cine CMR in short-axis, 2-ch, and 4-ch planes. Wall motion was scored using a standard 17-segment model with a 5-point scale. Global and regional (Ant, Sept, Inf, Lat) wall motion score indices (WMSI=wall motion score/# segments) were calculated with a WMSI>1 considered abnormal. LV ejection fraction (EF) and mass index (LVMI) were measured from the short axis stack. Adjudicated clinical events [CE; a history of coronary heart disease (CHD) or congestive heart failure (CHF)] were assessed. RESULTS: WMAs were present in 143 subjects. Compared to subjects with no prior CE, those with CE (n=157) had greater prevalence of WMA (Global, 34% vs 6%; Ant, 16% vs 2%; Sept, 18% vs 3%; Inf, 28% vs 4%; Lat, 27% vs 3%; all p<0.0001) and higher Framingham Risk Score (FRS) (11±3 vs 7±4, p<0.0001). In subjects with CE, WMA was associated with higher LVMI (70±14 g/m 2 vs 59±14 g/m 2 , p<0.0001) and lower EF (53±11% vs 69±6%, p<0.0001), but not age, blood pressure (BP), or FRS. Among 1637 subjects with no CE, 90 (5.5%) had a WMA. In these subjects, WMA was associated with greater age, BP, FRS, and LVMI, and lower EF (TABLE ). In the entire (n=1794) cohort, WMAs were more prevalent in men than in women (40% vs 19% with CE; 9% vs 3% without CE, respectively, both p<0.0001). CONCLUSIONS: In this closely followed free-living population, 5.5% of subjects have WMAs despite the absence of CE. WMAs were associated with other parameters of cardiovascular risk. The presence of WMAs among subjects without history of CHD or CHF may identify those at risk for adverse cardiovascular events.

Abstract Background Coronavirus disease 2019 (COVID-19) induces myocardial injury, either direct myocarditis or indirect injury due to systemic inflammatory response. Myocardial involvement has been proved to be one of the primary manifestations of COVID-19 infection, according to laboratory test, autopsy, and cardiovascular magnetic resonance (CMR). However, the middle-term outcome of cardiac involvement after the patients were discharged from the hospital is yet unknown. The present study aimed to evaluate mid-term cardiac sequelae in recovered COVID-19 patients by CMR Methods A total of 47 recovered COVID-19 patients were prospectively recruited and underwent CMR examination. The CMR protocol consisted of black blood fat-suppressed T2 weighted imaging, T2 star mapping, left ventricle (LV) cine imaging, pre- and post-contrast T1 mapping, and late gadolinium enhancement (LGE). LGE were assessed in mixed both recovered COVID-19 patients and healthy controls. The LV and right ventricle (RV) function and LV mass were assessed and compared with healthy controls. Results A total of 44 recovered COVID-19 patients and 31 healthy controls were studied. LGE was found in 13 (30%) of COVID-19 patients. All LGE lesions were located in the mid myocardium and/or sub-epicardium with a scattered distribution. Further analysis showed that LGE-positive patients had significantly decreased LV peak global circumferential strain (GCS), RV peak GCS, RV peak global longitudinal strain (GLS) as compared to non-LGE patients (p < 0.05), while no difference was found between the non-LGE patients and healthy controls. Conclusion Myocardium injury existed in 30% of COVID-19 patients. These patients have depressed LV GCS and peak RV strains at the 3-month follow-up. CMR can monitor the COVID-19-induced myocarditis progression, and CMR strain analysis is a sensitive tool to evaluate the recovery of LV and RV dysfunction.
