Objectives: This study sought to describe our institutional experience of repeated percutaneous stellate ganglion blockade (R-SGB) as a treatment option for drug-refractory electrical storm in patients with nonischemic cardiomyopathy (NICM). Methods: This prospective observational study included 8 consecutive NICM patients who had drug-refractory electrical storm and underwent R-SGB between June 1, 2021 and January 31, 2022. Lidocaine (5 ml, 1%) was injected in the vicinity of the left stellate ganglion under the guidance of ultrasound, once per day for 7 days. Data including clinical characteristics, immediate and long-term outcomes, and procedure related complications were collected. Results: The mean age was (51.5±13.6) years. All patients were male. 5 patients were diagnosed as dilated cardiomyopathy, 2 patients as arrhythmogenic right ventricular cardiomyopathy and 1 patient as hypertrophic cardiomyopathy. The left ventricular ejection fraction was 37.8%±6.6%. After the treatment of R-SGB, 6 (75%) patients were free of electrical storm. 24 hours Holter monitoring showed significant reduction in ventricular tachycardia (VT) episodes from 43.0 (13.3, 276.3) to 1.0 (0.3, 34.0) on the first day following R-SGB (P<0.05) and 0.5 (0.0, 19.3) after whole R-SGB process (P<0.05). There were no procedure-related major complications. The mean follow-up was (4.8±1.1) months, and the median time of recurrent VT was 2 months. Conclusion: Minimally invasive R-SGB is a safe and effective method to treat electrical storm in patients with NICM.

OBJECTIVE: To investigate the value of maximal rate of left ventricular pressure (dp/dtmax) in evaluating the changes of cardiac function before and after heart rate reduction in patients with sepsis-induced cardiomyopathy (SIC). METHODS: A single-center, prospective randomized controlled study was conducted. Adult patients with sepsis/septic shock admitted to the department of intensive care unit (ICU) of Tianjin Third Central Hospital from April 1, 2020 to February 28, 2022 were enrolled. Speckle tracking echocardiography (STE) and pulse indication continuous cardiac output (PiCCO) monitoring were performed immediately after the completion of the 1 h-Bundle therapy. The patients with heart rate over 100 beats/minutes were selected and randomly divided into esmolol group and regular treatment group, 55 cases in each group. All patients underwent STE and PiCCO monitoring at 6, 24 and 48 hours after admission in ICU and calculated acute physiology and chronic health evaluation II (APACHE II) and sequential organ failure assessment (SOFA). Primary outcome measure: change in dp/dtmax after reducing heart rate by esmolol. Secondary outcome measures: correlation between dp/dtmax and global longitudinal strain (GLS); changes of vasoactive drug dosage, oxygen delivery (DO₂), oxygen consumption (VO₂) and stroke volume (SV) after the administration of esmolol; proportion of heart rate reaching the target after the administration of esmolol; 28-day and 90-day mortality in two groups. RESULTS: Baseline data on age, gender, body mass index, SOFA score, APACHE II score, heart rate, mean arterial pressure, lactic acid, 24-hour fluid balance, sepsis etiology and prior comorbidities were similar between esmolol group and regular treatment group, there were no significant differences between the two groups. All SIC patients achieved the target heart rate after 24 hours of esmolol treatment. Compared with regular treatment group, parameters reflecting myocardial contraction such as GLS, global ejection fraction (GEF) and dp/dtmax were significantly increased in esmolol group [GLS: (-12.55±4.61)% vs. (-10.73±4.82)%, GEF: (27.33±4.62)% vs. (24.18±5.35)%, dp/dtmax (mmHg/s): 1 312.1±312.4 vs. 1 140.9±301.0, all P < 0.05], and N-terminal pro-brain natriuretic peptide (NT-proBNP) significantly decreased [μg/L: 1 364.52 (754.18, 2 389.17) vs. 3 508.85 (1 433.21, 6 988.12), P < 0.05], DO₂ and SV were significantly increased [DO₂ (mL×min^-1×m^-2): 647.69±100.89 vs. 610.31±78.56, SV (mL): 49.97±14.71 vs. 42.79±15.77, both P < 0.05]. The system vascular resistance index (SVRI) in esmolol group was significantly higher than that in regular treatment group (kPa×s×L^-1: 287.71±66.32 vs. 251.17±78.21, P < 0.05), even when the dosage of norepinephrine was similar between the two groups. Pearson correlation analysis showed that dp/dtmax was negatively correlated with GLS in SIC patients at 24 hours and 48 hours after ICU admission (r values were -0.916 and -0.935, respectively, both P < 0.05). Although there was no significant difference in 28-day mortality between esmolol group and regular treatment group [30.9% (17/55) vs. 49.1% (27/55), χ² = 3.788, P = 0.052], the rate of esmolol use in patients who died within 28 days was lower than that in patients who survived [38.6% (17/44) vs. 57.6% (38/66), χ² = 3.788, P = 0.040]. In addition, esmolol has no effect on the 90-day mortality of patients. Logistic regression analysis showed that after adjusting for SOFA score and DO₂ factors, patients who used esmolol had a significantly lower risk of 28-day mortality compared with patients who did not use esmolol [odds ratio (OR) = 2.700, 95% confidence interval (95%CI) was 1.038-7.023, P = 0.042]. CONCLUSIONS dp/dtmax in PiCCO parameter can be used as a bedside indicator to evaluate cardiac function in SIC patients due to its simplicity and ease of operation. Esmolol control of heart rate in SIC patients can improve cardiac function and reduce short-term mortality.

Protective effect of Qilong Capsules(QL) on the myocardial fibrosis and blood circulation of rats with coronary heart disease of Qi deficiency and blood stasis type was investigated. Sleep deprivation and coronary artery ligation were used to construct a disease-symptom combination model, and 60 SD rats were divided into sham operation(sham) group, syndrome(S) group, disease and syndrome(M) group and QL group randomly. The treatment group received administration of QL 0.4 g·kg~(-1)·d~(-1). Other groups were given the same amount of normal saline. The disease indexes of each group [left ventricular end diastolic diameter(LVESD), left ventricular end systolic diameter(LVEDD), left ventricular ejection fraction(LVEF), left ventricular axis shortening rate(LVFS), myocardial histopathology, platelet morphology, peripheral blood flow] and syndrome indexes(tongue color, pulse, grip power) were detected. In sham group, cardiomyocytes and myocardial fibers were arranged neatly and densely with clear structures. The tongues' color in sham were light red, and the pulse shape were regular. RGB is a parameter reflected the brightness of the image of the tongue. In the S group, the amplitude and frequency of the animal's pulse increased accompanied by decreasing R,G,B, however, the decreased R,G,B was accompanied by reduced pulse amplitude in M group. And in M group, we observed fuzzy cell morphology, hypertrophied myocytes, disordered arrangement of cardiomyocytes and myocardial fibers, reduced peripheral blood flow and increased collagen volume fraction(CVF). Increased LVESD and LVEDD, and decreased LVEF and LVFS represented cardiac function in S group was significantly lower than that in sham. In QL group, the tongue's color was red and the pulse was smooth. The myocardial fibers of the QL group were arranged neatly and secreted less collagen. It improved the blood circulation in the sole and tail, and reversed the increasing of LVEDD, LVESD and the decreasing of LVEF and LVFS of M group. Platelets in M and S group showed high reactivity, and QL could decrease aggregation risk. In conclusion, Qilong Capsules has an obvious myocardial protective effect on ischemic cardiomyopathy, which may inhibit the degree of myocardial fibrosis and reduce platelet reactivity.

Cream formula has been mostly used to treat deficiency syndrome. Currently,it has been used to recuperate the body,promote health against aging,and prevent and treat chronic disease. In modern medicine,there are only treatment concepts and methods of diseases,but lack of concepts of " deficiency syndrome" and " restoring deficiency". The concepts of " deficiency syndrome" and " restoring deficiency" could effectively supplement and improve the diagnosis and treatment scheme of some modern diseases. Refractory heart failure,dilated cardiomyopathy,ischemic cardiomyopathy,and valvular heart disease belong to the traditional category of " consumptive disease". The cream formula with the efficacy of restoring deficiency can not only alleviate symptoms and improve the quality of life,but also improve the structure and function of the heart,reduce the dosage of diuretics and the number of hospitalizations,and achieve the purpose of secondary prevention in the treatment of severe heart failure,dilated cardiomyopathy,ischemic cardiomyopathy and valvular heart disease. The cream formula for treating chronic heart failure include Shenqi Pills,Zhenwu Decoction,Yougui Pills,Wuling Powder,Linggui Zhugan Decoction,Danggui Shaoyao Powder,Lizhong Decoction,Buzhong Yiqi Decoction,Guipi Decoction,Yupingfeng Powder,Guizhi Decoction. Long-term administration of cream formula could not only resist aging,but also play an irreplaceable role in the secondary prevention of acute and critical diseases.
