Multisystemic Inflammation Influences Prognosis in Fulminant Lymphocytic Myocarditis

BACKGROUND

Multisystem inflammatory syndrome (MIS) is a hyperinflammatory shock associated with cardiac dysfunction and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. However, there are no reports on using MIS criteria, such as multisystemic inflammation (MSI) in fulminant myocarditis, without SARS-CoV-2 infection. This study investigated the differences in clinical characteristics and course between patients with fulminant lymphocytic myocarditis (FLM) plus MSI and those without MSI.

METHODS AND RESULTS

This multicenter retrospective cohort study included 273 patients with FLM registered in the JROAD-DPC database between April 2014 and March 2017. We evaluated the presence of MSI using criteria modified from previously reported MIS criteria and compared the characteristics and risk of mortality or heart transplantation between FLM patients with MSI and without MSI. Of the 273 patients with FLM, 107 (39%) were diagnosed with MSI. The MSI group was younger (44 vs. 57 years; P<0.0001) and had more females (50% vs. 36%; P=0.0236), a higher incidence of pericardial effusion (58% vs. 40%; P=0.0073), and a lower 90-day mortality rate (19% vs. 33%; P=0.0185) than the non-MSI group. The risk of mortality at 90 days was lower in FLM patients aged <50 years with MSI aged <50 years than in those without MSI (P=0.0463).

CONCLUSIONS

These results suggest that MSI may influence the prognosis of FLM, especially in patients aged <50 years.

Caught Between Heart and Limbs: Navigating the Treatment of Patients With CAD and PAD in an Overwhelmed Healthcare System

Peripheral arterial disease (PAD) and coronary artery disease (CAD) are manifestations of atherosclerosis, affecting a substantial proportion of the population. Despite their interrelation, the prevalence of CAD in severe PAD varies, prompting the need to understand their complex relationship. This study retrospectively analyzes prospectively collected data from a high-volume vascular center to assess CAD prevalence, risk factors, and implications for patients undergoing vascular surgery. Among 667 arterial disease patients, 19.5% underwent coronary angiography, with CAD detected in 61.5% of cases. CAD varied across vascular beds. Decision-making around preoperative coronary angiography and revascularization remains complex, with benefits for high-risk patients still being debated. In accordance with current guidelines, the routine practice of coronary revascularization preceding vascular surgery is generally discouraged. This study underscores the need for risk stratification to identify patients who might benefit from coronary revascularization prior to vascular surgery while adhering to cost-effectiveness and avoiding unnecessary and time-consuming diagnostics in the majority of patients. Patient demographics, risk factors, and clinical presentation were analyzed alongside hospital stay, mortality, and complications. The study highlights the challenges in managing patients with concurrent CAD and PAD and calls for improved protocols for treating this high-risk group.

Contemporary prevalence of coronary artery disease in patients referred for heart valve surgery

BACKGROUND

Patients undergoing heart valve surgery are routinely evaluated for the presence of coronary artery disease (CAD). Currently, concomitant valve intervention and surgical revascularization is recommended when there is obstructive CAD. The aim of our study was to evaluate the prevalence of CAD, its treatment strategies, and their prognostic implications in a contemporary population of patients with valvular heart disease (VHD) referred for valve surgery (HVS).

METHODS

In a multicenter registry, consecutive patients with formal indication for HVS referred for a preoperative routine invasive coronary angiogram (ICA) were analyzed. Baseline characteristics, CAD prevalence and revascularization patterns, as well as their impact on short and mid-term all-cause mortality, were assessed.

RESULTS

Overall, 1133 patients were included; most had aortic stenosis (69%) and obstructive CAD was present in 307 (27.1%). HVS was ultimately performed in 82.3%. In patients with CAD, 53.4% were revascularized. After a mean follow-up time of 29.06±18.46 months, all-cause mortality rate was 12.9%. In multivariate analysis, not having HVS (HR 6.845, 95% CI=4.281-10.947, P<0.001), obstructive CAD (HR 2.762, 95% CI=1.764-4.326, P<0.01), COPD (HR 2.043, 95% CI=1.014-4.197, P=0.022), and age (HR 1.030, 95% CI=1.009-1.063, P=0.047), were independent predictors of all-cause mortality. In patients with obstructive CAD who underwent HVS, revascularization was not significantly associated with survival (HR 2.127, 95% CI=0.0-4.494, P=0.048; log rank P=0.042).

CONCLUSIONS

In a contemporary cohort of patients with VHD and surgical indication, overall obstructive CAD prevalence was 27%. CAD presence and severity were associated with higher mortality. However, revascularization was not associated with a survival benefit, except in patients with left anterior descending artery disease.

Effect of Combined Etomidate-Ketamine Anesthesia on Perioperative Electrocardiogram and Postoperative Cognitive Dysfunction of Elderly Patients with Rheumatic Heart Valve Disease Undergoing Heart Valve Replacement

Objective

To explore the effect of combined etomidate-ketamine anesthesia on perioperative electrocardiogram (ECG) and postoperative cognitive dysfunction (POCD) of elderly patients with rheumatic heart valve disease (RHVD) undergoing heart valve replacement.

Methods

The data of 100 elderly RHVD patients treated in our hospital from May 2019 to May 2020 were selected for the retrospective analysis, and by adopting the double-blind method, the patients were divided into the ketamine group (n = 50) and the combined group (n = 50) according to the anesthesia methods. During the induction of anesthesia, the patients of the two groups were given a small dose of ketamine (0.5 mg/kg) at 5 μg/kg/min continuously via pump injection until the end of surgery, and on this basis, with the same anesthesia measures, those in the combined group were given etomidate (0.3 mg/kg) additionally. The patients' perioperative ECG indicators, POCD scores, and Numeric Rating Scale (NRS) scores were compared between the two groups.

Results

Compared with the ketamine group, the combined group presented significantly lower incidence of ST-T wave changes after anesthesia induction and at the time of intubation and skin incision (P < 0.05), significantly lower average magnitude of ST-segment depression after anesthesia induction (P < 0.001), significantly lower average magnitude of ST-segment elevation after anesthesia induction and extubation (P < 0.001), significantly lower POCD incidence (6.%, P < 0.05), and significantly better NRS score after surgery (P < 0.001).

Conclusion

Combined etomidate-ketamine anesthesia can stabilize the perioperative ECG indicators of elderly RHVD patients undergoing heart valve replacement, improve their postoperative cognitive function, and reduce their pain sensation, which should be promoted and applied in practice.

Evaluation of SERENE-CAG score for assessing suitability for coronary angiography preoperatively in patients undergoing valve replacement surgery

AIMS

The aim of this study was to identify better selection criteria for subjecting patients of rheumatic heart disease (RHD) to preoperative coronary angiography (CAG) based on indigenous scoring system (SERENE-CAG [Selecting Patients Of Rheumatic Heart Disease Undergoing Valve Surgery For Presurgical Coronary Angiography]).

METHODS

This prospective study included all consecutive 798 patients of RHD patients undergoing preoperative CAG from January 2016 to December 2017 over a duration of 2 years. Multivariate logistic regression analysis was performed with the presence of significant CAD [coronary artery disease] as the dependent variable with traditional risk factors of CAD. An additive score was developed using coefficient derived logistic regression for those variables that were significant. Receiver-operator curve analysis was performed to assess the ability of this score to predict diseased vs normal CAG.

RESULTS

A total of 798 patients had a mean age of 51.7 ± 12.5 years. Significant CAD requiring revascularization along with valve surgery was identified in 50 (6.26%) patients. Male gender was found as significant predictors of CAD with odds ratio 2.6. A SERENE CAG SCORE of >2.8 resulted in sensitivity of 80% and specificity of 36.9% of predicting CAD in RHD patients with positive and negative predictive value of 7.8% and 96.5%, respectively.

CONCLUSION

The prevalence of CAD in RHD patients is low. Patient risk can be minimized by exploring noninvasive modalities for screening of CAD and by more appropriate selection of patients for invasive coronary angiogram. Using threshold SERENE-CAG score of >2.8 would result in deferring 34.6% of normal angiograms.
