Chronic coronary syndromes without standard modifiable cardiovascular risk factors and outcomes: the CLARIFY registry.

BACKGROUND AND AIMS: It has been reported that patients without standard modifiable cardiovascular (CV) risk factors (SMuRFs-diabetes, dyslipidaemia, hypertension, and smoking) presenting with first myocardial infarction (MI), especially women, have a higher in-hospital mortality than patients with risk factors, and possibly a lower long-term risk provided they survive the post-infarct period. This study aims to explore the long-term outcomes of SMuRF-less patients with stable coronary artery disease (CAD). METHODS: CLARIFY is an observational cohort of 32 703 outpatients with stable CAD enrolled between 2009 and 2010 in 45 countries. The baseline characteristics and clinical outcomes of patients with and without SMuRFs were compared. The primary outcome was a composite of 5-year CV death or non-fatal MI. Secondary outcomes were 5-year all-cause mortality and major adverse cardiovascular events (MACE-CV death, non-fatal MI, or non-fatal stroke). RESULTS: Among 22 132 patients with complete risk factor and outcome information, 977 (4.4%) were SMuRF-less. Age, sex, and time since CAD diagnosis were similar across groups. SMuRF-less patients had a lower 5-year rate of CV death or non-fatal MI (5.43% [95% CI 4.08-7.19] vs. 7.68% [95% CI 7.30-8.08], P = 0.012), all-cause mortality, and MACE. Similar results were found after adjustments. Clinical event rates increased steadily with the number of SMuRFs. The benefit of SMuRF-less status was particularly pronounced in women. CONCLUSIONS: SMuRF-less patients with stable CAD have a substantial but significantly lower 5-year rate of CV death or non-fatal MI than patients with risk factors. The risk of CV outcomes increases steadily with the number of risk factors.

Left ventricular global longitudinal strain and acute myocardial injury in patients with sickle cell disease admitted to the intensive care unit for vaso-occlusive crisis.

In patients with sickle cell disease (SCD), SCD-related cardiomyopathy may be partly due to repeated ischaemic events related to sickling during vaso-occlusive crises, but few clinical studies support this hypothesis. We evaluated the incidence of acute myocardial ischaemia during vaso-occlusive crises as assessed by the left ventricular global longitudinal strain (LVGLS) and high-sensitive cardiac troponin T (hs-cTnT). We included adult patients with SCD admitted to the intensive care unit (ICU) for vaso-occlusive crisis. We collected hs-cTnT and measured LVGLS with echocardiography at admission (day 1), day 2, day 3 and ICU discharge. Among 55 patients included, considering only the first hospitalization of patients admitted several times, 3 (5%) had elevated hs-cTnT at ≥1 time point of the ICU stay. It was ≤2 times the upper limit of normal in two of these patients. LVGLS was altered at ≥1 time point of the ICU stay in 13 (24%) patients. Both hs-cTnT and LVGLS were abnormal at ≥1 time point of the hospital stay in 2 (4%) patients. Acute myocardial injury as assessed by troponin elevation and LVGLS impairment was a rare event during vaso-occlusive crises.

Incidence of deep venous thrombosis in COVID-19 critically ill patients treated with intermediate-dose of heparin for thromboprophylaxis: The COVIDOP-DVT observational study.

INTRODUCTION: The high prevalence of deep vein thrombosis (DVT) in patients admitted to intensive care unit (ICU) for COVID-19-related acute respiratory distress syndrome (ARDS) would justify systematic screening of these patients or higher therapeutic dose of heparin for thromboprophylaxis. MATERIAL AND METHOD: We performed a systematic echo-Doppler of the lower limb proximal veins during the first 48 h (visit 1) and from 7 to 9 days after visit 1 (visit 2) in consecutive patients admitted to the ICU of a university-affiliated tertiary hospital for severe proven COVID-19 during the second wave. All patients received intermediate-dose heparin (IDH). The primary objective was to determine DVT incidence on venous Doppler ultrasound. Secondary objectives were to determine whether the presence of DVT modifies the anticoagulation regimen, the incidence of major bleeding according to International Society on Thrombosis and Haemostasis (ISTH) criteria, and the mortality rate of patients with and without DVT. RESULTS: We included 48 patients (30 [62.5%] men) with a median age of 63 years [IQR, 54-70]. The prevalence of proximal deep vein thrombosis was 4.2% (2/48). In these two patients, after DVT diagnosis, anticoagulation was changed from intermediate to curative dose. Two patients (4.2%) had a major bleeding complication according to ISTH criteria. Among the 48 patients, 9 (18.8%) died before hospital discharge. No DVT or pulmonary embolism was diagnosed in these deceased patients during their hospital stay. CONCLUSION: In critically ill patients with COVID-19, management with IDH results in a low incidence of DVT. Although our study is not designed to demonstrate any difference in outcome, our results do not suggest any signal of harm when using intermediate-dose heparin (IDH) COVID-19 with a frequency of major bleeding complications less than 5%.

Positive association of angiotensin II receptor blockers, not angiotensin-converting enzyme inhibitors, with an increased vulnerability to SARS-CoV-2 infection in patients hospitalized for suspected COVID-19 pneumonia.

BACKGROUND: Angiotensin-converting enzyme 2 is the receptor that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) uses for entry into lung cells. Because ACE-2 may be modulated by angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs), there is concern that patients treated with ACEIs and ARBs are at higher risk of coronavirus disease 2019 (COVID-19) pneumonia. AIM: This study sought to analyze the association of COVID-19 pneumonia with previous treatment with ACEIs and ARBs. MATERIALS AND METHODS: We retrospectively reviewed 684 consecutive patients hospitalized for suspected COVID-19 pneumonia and tested by polymerase chain reaction assay. Patients were split into two groups, according to whether (group 1, n = 484) or not (group 2, n = 250) COVID-19 was confirmed. Multivariable adjusted comparisons included a propensity score analysis. RESULTS: The mean age was 63.6 ± 18.7 years, and 302 patients (44%) were female. Hypertension was present in 42.6% and 38.4% of patients in groups 1 and 2, respectively (P = 0.28). Treatment with ARBs was more frequent in group 1 than group 2 (20.7% vs. 12.0%, respectively; odds ratio [OR] 1.92, 95% confidence interval [CI] 1.23-2.98; P = 0.004). No difference was found for treatment with ACEIs (12.7% vs. 15.7%, respectively; OR 0.81, 95% CI 0.52-1.26; P = 0.35). Propensity score-matched multivariable logistic regression confirmed a significant association between COVID-19 and previous treatment with ARBs (adjusted OR 2.36, 95% CI 1.38-4.04; P = 0.002). Significant interaction between ARBs and ACEIs for the risk of COVID-19 was observed in patients aged > 60 years, women, and hypertensive patients. CONCLUSIONS: This study suggests that ACEIs and ARBs are not similarly associated with COVID-19. In this retrospective series, patients with COVID-19 pneumonia more frequently had previous treatment with ARBs compared with patients without COVID-19.
