RESUMEN
BACKGROUND: Myocarditis is commonly diagnosed in the intensive care cardiology unit (ICCU). No current recommendation nor guideline aids exist for aetiological assessments. METHODS: From September 2021 to October 2023, 84 patients with acute myocarditis underwent thorough and systematic serum and blood cell panel evaluations to determine the most common causes of myocarditis. RESULTS: Of the 84 patients (median age 34 years, range 22-41 years, 79% male), 16 presented with complicated myocarditis. The systematic aetiological assessment revealed that 36% of patients were positive for lupus anticoagulant, 12% for antinuclear antibodies, 8% for anti-heart antibodies, and 12% for anti-striated muscle antibodies. Viral serology did not yield any significant results. After the aetiological assessment, one patient was diagnosed with an autoimmune inflammatory disorder (Still's disease). T-cell subset analyses indicated that myocarditis severity tended to increase with the T-cell lymphopenia status. CONCLUSIONS: A comprehensive, systematic aetiological assessment was of limited value in terms of predicting the clinical or therapeutic outcomes in myocarditis patients presenting to the ICCU.
RESUMEN
Inflammatory processes are involved not only in coronary artery disease but also in heart failure (HF). Cardiogenic shock (CS) and septic shock are classically distinct although intricate relationships are frequent in daily practice. The impact of admission inflammation in patients with CS is largely unknown. FRENSHOCK is a prospective registry including 772 CS patients from 49 centers. One-month and one-year mortalities were analyzed according to the level of C-reactive protein (CRP) at admission, adjusted on independent predictive factors. Within 406 patients included, 72.7% were male, and the mean age was 67.4 y ± 14.7. Four groups were defined, depending on the quartiles of CRP at admission. Q1 with a CRP < 8 mg/L, Q2: CRP was 8-28 mg/L, Q3: CRP was > 28-69 mg/L, and Q4: CRP was > 69 mg/L. The four groups did not differ regarding main baseline characteristics. However, group Q4 received more often antibiotics in 47.5%, norepinephrine in 66.3%, and needed more frequently respiratory support and renal replacement therapy. Whether at 1 month (Ptrend = 0.01) or 1 year (Ptrend < 0.01), a strong significant trend towards increased all-cause mortality was observed across CRP quartiles. Specifically, compared to the Q1 group, Q4 patients demonstrated a 2.2-fold higher mortality rate at 1-month (95% CI 1.23-3.97, p < 0.01), which persisted at 1-year, with a 2.14-fold increase in events (95% CI 1.43-3.22, p < 0.01). Admission CRP level is a strong independent predictor of mortality at 1 month and 1-year in CS. Specific approaches need to be developed to identify accurately patients in whom inflammatory processes are excessive and harmful, paving the way for innovative approaches in patients admitted for CS.NCT02703038.

Background: Smoking cigarettes produces carbon monoxide (CO), which can reduce the oxygen-carrying capacity of the blood. We aimed to determine whether elevated expiratory CO levels would be associated with a worse prognosis in smokers presenting with acute cardiac events. Methods: From 7 to 22 April 2021, expiratory CO levels were measured in a prospective registry including all consecutive patients admitted for acute cardiac event in 39 centres throughout France. The primary outcome was 1-year all-cause death. Initial in-hospital major adverse cardiac events (MAE; death, resuscitated cardiac arrest and cardiogenic shock) were also analysed. The study was registered at ClinicalTrials.gov (NCT05063097). Findings: Among 1379 patients (63 ± 15 years, 70% men), 368 (27%) were active smokers. Expiratory CO levels were significantly raised in active smokers compared to non-smokers. A CO level >11 parts per million (ppm) found in 94 (25.5%) smokers was associated with a significant increase in death (14.9% for CO > 11 ppm vs. 2.9% for CO ≤ 11 ppm; p < 0.001). Similar results were found after adjustment for comorbidities (hazard ratio [HR] [95% confidence interval (CI)]): 5.92 [2.43-14.38]) or parameters of in-hospital severity (HR 6.09, 95% CI [2.51-14.80]) and propensity score matching (HR 7.46, 95% CI [1.70-32.8]). CO > 11 ppm was associated with a significant increase in MAE in smokers during initial hospitalisation after adjustment for comorbidities (odds ratio [OR] 15.75, 95% CI [5.56-44.60]) or parameters of in-hospital severity (OR 10.67, 95% CI [4.06-28.04]). In the overall population, CO > 11 ppm but not smoking was associated with an increased rate of all-cause death (HR 4.03, 95% CI [2.33-6.98] and 1.66 [0.96-2.85] respectively). Interpretation: Elevated CO level is independently associated with a 6-fold increase in 1-year death and 10-fold in-hospital MAE in smokers hospitalized for acute cardiac events.

RESUMEN
BACKGROUND: The incidence of heart failure and cardiogenic shock (CS) in older adults is continually increasing due to population aging. To date, prospective data detailing the specific characteristics, management and outcomes of CS in this population are scarce. METHODS: FRENSHOCK is a prospective registry including 772 CS patients from 49 centers. We studied 1-month and 1-year mortality among patients over 75-year-old, adjusted for independent predictors of 1-month and 1-year mortalities. RESULTS: Out of 772 patients included, 236 (30.6%) were 75 years old or more (mean age 81.9 ± 4.7 years, 63.6% male). Compared to patients <75 years old, older adults had a higher prevalence of comorbidities including hypertension, dyslipidemia, chronic kidney disease, and history of heart disease. Older adults were characterized by a lower blood pressure, as well as higher creatinine and lower haemoglobin levels at presentation. Yet, they were less likely to be treated with norepinephrine, epinephrine, invasive ventilation, and renal replacement therapy. They showed a higher 1-month (aHR: 2.5 [1.86-3.35], p < 0.01) and 1-year mortality (aHR: 2.01 [1.58-2.56], p < 0.01). Analysis of both 1-month and 1-year mortality stratified by age quartiles showed a gradual relationship between aging and mortality in CS patients. CONCLUSION: A third of patient with CS in critical care unit are older than 75 years and their risk of death at one month and one year is more than double compared to the younger ones. Further research is essential to identify best therapeutic strategy in this population. NCT02703038.

BACKGROUND: Cardiogenic shock and sepsis are severe haemodynamic states that are frequently present concomitantly, leading to substantial mortality. Despite its frequency and clinical significance, there is a striking lack of literature on the outcomes of combined sepsis and cardiogenic shock. METHODS: FRENSHOCK was a prospective registry including 772 patients with cardiogenic shock from 49 centres. The primary endpoint was 1-month all-cause mortality. Secondary endpoints included heart transplantation, ventricular assistance device and all-cause death rate at 1year. RESULTS: Among the 772 patients with cardiogenic shock included, 92 cases were triggered by sepsis (11.9%), displaying more frequent renal and hepatic acute injuries, with lower mean arterial pressure. Patients in the sepsis group required broader use of dobutamine (90.1% vs. 81.2%; P=0.16), norepinephrine (72.5% vs. 50.8%; P<0.01), renal replacement therapy (29.7% vs. 14%; P<0.01), non-invasive ventilation (36.3% vs. 24.4%; P=0.09) and invasive ventilation (52.7% vs. 35.9%; P=0.02). Sepsis-triggered cardiogenic shock resulted in higher 1-month (41.3% vs. 24.0%; adjusted hazard ratio: 1.94, 95% confidence interval: 1.36-2.76; P<0.01) and 1-year (62.0% vs. 42.9%; adjusted hazard ratio 1.75, 95% confidence interval 1.32-2.33; P<0.01) all-cause death rates. No significant difference was found at 1year for heart transplantation or ventricular assistance device (8.7% vs. 10.3%; adjusted odds ratio 0.72, 95% confidence interval 0.32-1.64; P=0.43). In patients with sepsis-triggered cardiogenic shock, neither the presence of a preexisting cardiomyopathy nor the co-occurrence of other cardiogenic shock triggers had any additional impact on death. CONCLUSIONS: The association between sepsis and cardiogenic shock represents a common high-risk scenario, leading to higher short- and long-term death rates, regardless of the association with other cardiogenic shock triggers or the presence of preexisting cardiomyopathy.
RESUMEN
BACKGROUND: The effects of pharmacological therapy on cardiogenic shock (CS) survivors have not been extensively studied. Thus, this study investigated the association between guideline-directed heart failure (HF) medical therapy (GDMT) and one-year survival rate in patients who are post-CS. METHODS AND RESULTS: FRENSHOCK (French Observatory on the Management of Cardiogenic Shock in 2016) registry was a prospective multicenter observational survey, conducted in metropolitan French intensive care units and intensive cardiac care units. Of 772 patients, 535 patients were enrolled in the present analysis following the exclusion of 217 in-hospital deaths and 20 patients with missing medical records. Patients with triple GDMT (beta-blockers, renin-angiotensin system inhibitors, and mineralocorticoid receptor antagonists) at discharge (n=112) were likely to have lower left ventricular ejection fraction on admission and at discharge compared with those without triple GDMT (n=423) (22% versus 28%, P<0.001 and 29% versus 37%, P<0.001, respectively). In the overall cohort, the one-year mortality rate was 23%. Triple GDMT prescription was significantly associated with a lower one-year all-cause mortality compared with non-triple GDMT (adjusted hazard ratio 0.44 [95% CI, 0.19-0.80]; P=0.007). Similarly, 2:1 propensity score matching and inverse probability treatment weighting based on the propensity score demonstrated a lower incidence of one-year mortality in the triple GDMT group. As the number of HF drugs increased, a stepwise decrease in mortality was observed (log rank; P<0.001). CONCLUSIONS: In survivors of CS, the one-year mortality rate was significantly lower in those with triple GDMT. Therefore, this study suggests that intensive HF therapy should be considered in patients following CS.

AIMS: Although several studies have shown that the right ventricular to pulmonary artery (RV-PA) coupling, assessed by the ratio between tricuspid annular plane systolic excursion and systolic pulmonary artery pressure (TAPSE/sPAP) using echocardiography, is strongly associated with cardiovascular events, its prognostic value is not established in acute coronary syndrome (ACS). We aimed to assess the in-hospital prognostic value of TAPSE/sPAP among patients hospitalized for ACS in a retrospective analysis from the prospective ADDICT-ICCU study. METHODS AND RESULTS: 481 consecutive patients hospitalized in intensive cardiac care unit (mean age 65±13 years, 73% of male, 46% STEMI) for ACS (either ST-elevation [STEMI] or non-ST-elevation [NSTEMI] myocardial infarction) with TAPSE/sPAP available were included in this prospective French multicentric study (39 centers). The primary outcome was in-hospital major adverse cardiovascular events (MACEs) defined as all-cause death, resuscitated cardiac arrest or cardiogenic shock and occurred in 33 (7%) patients. ROC-curve analysis identified 0.55 mm/mmHg as the best TAPSE/sPAP cut-off to predict in-hospital MACEs. TAPSE/sPAP <0.55 was associated with in-hospital MACEs, even after adjustment with comorbidities (OR:19.1, 95%CI[7.78-54.8]), clinical severity including left ventricular ejection fraction (OR:14.4, 95%CI[5.70-41.7]) and propensity-matched population analysis (OR:22.8, 95%CI[7.83-97.2], all p<0.001). After adjustment, TAPSE/sPAP <0.55 showed the best improvement in model discrimination and reclassification above traditional prognosticators (C-statistic improvement: 0.16; global chi-square improvement: 52.8; LR-test p<0.001) with similar results for both STEMI and NSTEMI subgroups. CONCLUSION: A low RV-PA coupling defined as TAPSE/sPAP ratio <0.55 was independently associated with in-hospital MACEs and provided incremental prognostic value over traditional prognosticators in patients hospitalized for ACS.

RESUMEN
BACKGROUND: Chronic kidney disease (CKD) is one of the leading causes of death worldwide, closely interrelated with cardiovascular diseases, ultimately leading to the failure of both organs - the so-called "cardiorenal syndrome". Despite this burden, data related to cardiogenic shock outcomes in CKD patients are scarce. METHODS: FRENSHOCK (NCT02703038) was a prospective registry involving 772 patients with cardiogenic shock from 49 centres. One-year outcomes (rehospitalization, death, heart transplantation, ventricular assist device) were analysed according to history of CKD at admission and were adjusted on independent predictive factors. RESULTS: CKD was present in 164 of 771 patients (21.3%) with cardiogenic shock; these patients were older (72.7 vs. 63.9years) and had more comorbidities than those without CKD. CKD was associated with a higher rate of all-cause mortality at 1month (36.6% vs. 23.2%; hazard ratio 1.39, 95% confidence interval 1.01-1.9; P=0.04) and 1year (62.8% vs. 40.5%, hazard ratio 1.39, 95% confidence interval 1.09-1.77; P<0.01). Patients with CKD were less likely to be treated with norepinephrine/epinephrine or undergo invasive ventilation or receive mechanical circulatory support, but were more likely to receive renal replacement therapy (RRT). RRT was associated with a higher risk of all-cause death at 1month and 1year regardless of baseline CKD status. CONCLUSIONS: Cardiogenic shock and CKD are frequent "cross-talking" conditions with limited therapeutic options, resulting in higher rates of death at 1month and 1year. RRT is a strong predictor of death, regardless of preexisting CKD. Multidisciplinary teams involving cardiac and kidney physicians are required to provide integrated care for patients with failure of both organs.

BACKGROUND: Cardiogenic shock (CS) is the most severe form of acute heart failure. Discrepancies have been reported between sexes regarding delays, pathways and invasive strategies in CS complicating acute myocardial infarction. However, effect of sex on the prognosis of unselected CS remains controversial. OBJECTIVES: The aim was to analyze the impact of sex on aetiology, management and prognosis of CS. METHODS: The FRENSHOCK registry included all CS admitted in 49 French Intensive Care Units (ICU) and Intensive Cardiac Care Units (ICCU) between April and October 2016. RESULTS: Among the 772 CS patients included, 220 were women (28.5%). Women were older, less smokers, with less history of ischemic cardiac disease (20.5% vs 33.6%) than men. At admission, women presented less cardiac arrest (5.5 vs 12.2%), less mottling (32.5 vs 41.4%) and higher LVEF (30 ± 14 vs 25 ± 13%). Women were more often managed via emergency department while men were directly admitted at ICU/ICCU. Ischemia was the most frequent trigger irrespective of sex (36.4% in women vs 38.2%) but women had less coronary angiogram and PCI (45.9% vs 54% and 24.1 vs 31.3%, respectively). We found no major difference in medication and organ support. Thirty-day mortality (26.4 vs 26.5%), transplant or permanent assist device were similar in both sexes. CONCLUSION: Despite some more favorable parameters in initial presentation and no significant difference in medication and support, women shared similar poor prognosis than men. Further analysis is required to cover the lasting gap in knowledge regarding sex specificities to distinguish between differences and inequalities. NCT02703038.

BACKGROUND: Beta blockers (BBs) are a cornerstone for patients with heart failure (HF) and ventricular dysfunction. However, their use in patients recovering from a cardiogenic shock (CS) remains a bone of contention, especially regarding whether and when to reintroduce this class of drugs. METHODS: FRENSHOCK is a prospective multicenter registry including 772 CS patients from 49 centers. Our aim was to compare outcomes (1-month and 1-year all-cause mortality) between CS patients taking and those not taking BBs in three scenarios: (1) at 24 h after CS; (2) patients who did or did not discontinue BBs within 24 h; and (3) patients who did or did not undergo the early introduction of BBs. RESULTS: Among the 693 CS included, at 24 h after the CS event, 95 patients (13.7%) were taking BB, while 598 (86.3%) were not. Between the groups, there were no differences in terms of major comorbidities or initial CS triggers. Patients receiving BBs at 24 h presented a trend toward reduced all-cause mortality both at 1 month (aHR = 0.61, 95% CI 0.34 to 1.1, p = 0.10) and 1 year, which was, in both cases, not significant. Compared with patients who discontinued BBs at 24 h, patients who did not discontinue BBs showed lower 1-month mortality (aHR = 0.43, 95% CI 0.2 to 0.92, p = 0.03) and a trend to lower 1-year mortality. No reduction in outcomes was observed in patients who underwent an early introduction of BB therapy. CONCLUSIONS: BBs are drugs of first choice in patients with HF and should also be considered early in patients with CS. In contrast, the discontinuation of BB therapy resulted in increased 1-month all-cause mortality and a trend toward increased 1-year all-cause mortality.
