Impact of Coronavirus Disease 2019 outbreak on acute coronary syndrome admissions: four weeks to reverse the trend.

Data whether the COVID-19 outbreak impacts the acute coronary syndromes (ACS) admissions and the time required to reverse the downward curve are scarce. We included all consecutive patients referred for an ACS who underwent PCI from February 17, 2020 to April 26, 2020 in a high-volume PCI coronary care unit. We compared the number of ACS patients in 2020 to the same period in 2018 and 2019. Predictors of adverse outcome in ST-elevation myocardial infarction (STEMI) patients were recorded: symptom-onset-to-first medical contact (FMC), and FMC-to-sheath insertion times. During the studied period (calendar weeks 8-17, 2018-2020), 144 ACS patients were included. In 2020, we observed two distinct phases in the ACS admissions: a first significant fall, with a relative reduction of 73%, from the week of lockdown (week 12) to 3 weeks later and then an increase of ACS. Median symptom-onset-to-FMC time was significantly higher in 2020 than in the two previous years (600 min [298-632] versus 121 min [55-291], p < 0.001). Median FMC-to-sheath insertion did not differ significantly (93 min [81-131] in 2020 versus 90 min [67-137] in 2018-2019, p = 0.57). The main findings are (1) a pattern of a U-curve in ACS admissions, with a first decrease in ACS admissions and a return to "normality" 4 weeks after; (2) a significant increase in the total ischemic time exclusively due to an increase in the symptom-onset-to-first-medical-contact time.

Prevalence of familial hypercholesterolaemia in patients presenting with premature acute coronary syndrome.

BACKGROUND: Familial hypercholesterolaemia (FH) is responsible for severe hypercholesterolaemia and premature cardiovascular morbidity and mortality. The first clinical event is typically an acute coronary syndrome. Unfortunately, FH is largely underdiagnosed in the general population. AIMS: To assess the prevalence of clinical FH among patients with premature (aged≤50 years) acute myocardial infarction (MI) and compare it with FH prevalence in a control population. METHODS: We reviewed in our database all patients with premature MI (aged≤50 years) referred to Ambroise Paré Hospital from 2014 to 2018. FH prevalence was estimated via the Dutch Lipid Clinic Network score, based on personal and family history of premature cardiovascular disease and low-density lipoprotein cholesterol concentrations. FH was "possible" with a score between 3 and 5 points, "probable" with a score between 6 and 8 and "definite" with a score above 8. FH prevalence in young patients with MI was then compared with FH prevalence in a general population of the same age from the CARVAR 92 prospective cohort. RESULTS: Of the 457 patients with premature MI, 29 (6%) had "probable" or "definite" FH. In the CARVAR 92 cohort, 16 (0.16%) of 9900 subjects aged≤50 years had "probable" or "definite" FH. FH prevalence was 39 times greater among patients with premature MI than in the control population (P<0.0001). In multivariable analysis, FH was strongly associated with MI (adjusted odds ratio 38.4, 95% confidence interval 19.1-79.4). CONCLUSIONS: FH is>30-fold more common in patients referred for premature MI than in the general population; this highlights the need for FH screening after a first MI to enhance lipid-lowering therapy and allow early identification of family members.

Short and long-term outcome in very old patients with ST-elevation myocardial infarction after primary percutaneous coronary intervention.

BACKGROUND: Although octogenarians constitute a fast-growing portion of cardiovascular patients, few data are available on the outcome of patients aged ≥85 years with ST-Elevation Myocardial Infarction (STEMI). METHODS AND RESULTS: We analyzed 126 consecutive patients aged ≥85 years (age 88±2 years) with STEMI, undergoing primary percutaneous coronary intervention (pPCI) within 12 hours from symptoms onset. Long-term follow-up (median 898 days) was obtained for the 102 patients surviving the index-hospitalization. In-hospital mortality rate was 19%. Nonagenarians, diabetes mellitus, severe left ventricular systolic dysfunction and intra-aortic balloon pumping were significantly and independently correlated to in-hospital mortality at the multivariate analysis. A low rate of complications was detected. Among patients surviving the index hospitalization, 32 (31%) patients died during follow-up. 55 patients (54%) had re-hospitalization due to cardiovascular causes. The univariate analysis identified chronic renal failure, Killip class ≥ 3, TIMI Risk Score >8 and very high risk of bleeding as predictors of long-term overall mortality. At the multivariate analysis only chronic renal failure and very high risk of bleeding were significantly and independently correlated to long-term all-cause mortality. Renal function and anterior myocardial infarction were significantly and independently associated with the combined end-point of cardiac mortality and re-hospitalization due to cardiovascular disease at the multivariate analysis. CONCLUSIONS: PPCI in patients ≥85 years old is relatively safe. In this population, pPCI is associated with a good long-term survival, although still worse than in younger patients, despite a considerable incidence of re-hospitalization due to cardiovascular events.

Disseminated echinococcosis: follow your heart.

: In this report, we present a rare case of cardiac echinococcosis presenting with cerebral haemorrhage due to rupture of a mycotic aneurysm in a peripheral branch of the media cerebral artery. Further investigations lead to discovery of multiple cysts in the heart and liver. The complementary use of transthoracic and transoesophageal echocardiography, MRI and computed tomography lead to the final diagnosis of disseminated echinococcosis and allowed precise evaluation of the anatomical and structural characteristics of the cardiac mass, its boundaries and its relationship with the surrounding anatomic structures.

Right Ventricular Strain and Dyssynchrony Assessment in Arrhythmogenic Right Ventricular Cardiomyopathy: Cardiac Magnetic Resonance Feature-Tracking Study.

BACKGROUND: Analysis of right ventricular (RV) regional dysfunction by cardiac magnetic resonance (CMR) imaging in arrhythmogenic RV cardiomyopathy (ARVC) may be inadequate because of the complex contraction pattern of the RV. Aim of this study was to determine the use of RV strain and dyssynchrony assessment in ARVC using feature-tracking CMR analysis. METHODS AND RESULTS: Thirty-two consecutive patients with ARVC referred to CMR imaging were included. Thirty-two patients with idiopathic RV outflow tract arrhythmias and 32 control subjects, matched for age and sex to the ARVC group, were included for comparison purpose. CMR imaging was performed to assess biventricular function; feature-tracking analysis was applied to the cine CMR images to assess regional and global longitudinal, circumferential, and radial RV strains and RV dyssynchrony (defined as the SD of the time-to-peak strain of the RV segments). RV global longitudinal strain (-17±5% versus -26±6% versus -29±6%; P<0.001), global circumferential strain (-9±4% versus -12±4% versus -13±5%; P=0.001), and global radial strain (18 [12-26]% versus 22 [15-32]% versus 27 [20-39]%; P=0.015) were significantly lower and SD of the time-to-peak RV strain in all 3 directions were significantly higher among patients with ARVC compared with patients with RV outflow tract arrhythmias and controls. RV global longitudinal strain >-23.2%, SD of the time-to-peak RV longitudinal strain >113.1 ms, and SD of the time-to-peak RV circumferential strain >177.1 ms allowed correct identification of 88%, 75%, and 63% of ARVC patients with no or only minor CMR criteria for ARVC diagnosis. CONCLUSIONS: Strain analysis by feature-tracking CMR helps to objectively quantify global and regional RV dysfunction and RV dyssynchrony in patients with ARVC and provides incremental value over conventional cine CMR imaging.
