Resumen Objetivo: El objetivo del presente estudio es evaluar en nuestro medio la prevalencia de anemia en el preoperatorio de la cirugía cardiovascular, su incidencia postoperatoria y su evolución durante el primer mes. Métodos: Se realizó un estudio de cohorte prospectivo en el que se incluyeron todos los pacientes sometidos a cirugía cardiovascular central intervenidos durante el periodo del 01/09/2021 al 01/09/2022 en un hospital universitario. Se realizó seguimiento clínico y de laboratorio previo a la cirugía, al quinto y al día treinta del postoperatorio. Se comparó a los grupos con y sin anemia preoperatoria. Resultados: La prevalencia de anemia en el preoperatorio fue del 32.1%. La incidencia de anemia en el postoperatorio fue del 96% en el grupo de pacientes sin anemia previa. Al mes de la cirugía un 73 y un 90% de los pacientes, con y sin anemia preoperatoria respectivamente, persistían anémicos. Los pacientes con anemia preoperatoria tuvieron una menor recuperación de sus valores de hemoglobina al mes. Se observó una tendencia a mayor mortalidad y una mayor necesidad de derivación a centros de rehabilitación postegreso hospitalario en aquellos con anemia preoperatoria. Conclusiones: En este trabajo se evidenció una alta prevalencia e incidencia de anemia en el perioperatorio de las cirugías cardiovasculares. Así como su subtratamiento y elevada persistencia durante el mes posterior a la cirugía.

Abstract Objective: The aim of this study is to evaluate the prevalence of anemia in the preoperative period of cardiovascular surgery, its postoperative incidence and its evolution during the first month in our setting. Methods: A prospective cohort study was carried out in which all patients undergoing central cardiovascular surgery operated during the period 09/01/2021-09/01/2022 in a university hospital were included. Clinical and laboratory follow-up was carried out prior to surgery, on the fifth and on the 30th postoperative day. Groups with and without preoperative anemia were compared. Results: The prevalence of anemia in the preoperative period was 32.1%. The incidence of anemia in the postoperative period was 96% in the group of patients without previous anemia. One month after surgery, 73 and 90% of the patients, with and without preoperative anemia, respectively, remained anemic. Patients with preoperative anemia had less recovery of their hemoglobin values at one month. A trend towards higher mortality and a greater need for referral to post-hospital discharge rehabilitation centers was observed in those with preoperative anemia. Conclusions: In this work, a high prevalence and incidence of anemia in the perioperative period of cardiovascular surgeries was evidenced. As well as its subtreatment and high persistence during the month after surgery.

ABSTRACT Background Multiple mini-interviews (MMIs) serve as a model to evaluate non-cognitive skills in the admission process of health care professionals. Objective The aim of this study was to evaluate the feasibility, reliability and acceptability of the MMI model for the selection of residents and fellows in a cardiovascular center in the past 5 years. Methods We conducted an observational study including applicants to the cardiology residency program and to the fellowship in Nuclear Medicine and Cardiovascular Ultrasound in 2018, 2019 and 2022. Ten stations were developed to evaluate different non-cognitive domains. Reliability was assessed using G-coefficient. Applicants and interviewers were also surveyed to assess the acceptability of the MMI model and its feasibility in terms of the time required for the process. Results A total of 75 applicants participated in the MMIs. The G study showed reliability coefficients of 0.62 and 0.61 according to the design. Implementation was feasible; 92% of applicants gave positive reviews to the MMI model, and 90% of interviewers reported they had sufficient time to assess the participants and that the process was not an excessively exhausting. Conclusion MMIs are a novel method in our setting, demonstrating reliability and a high level of acceptability for evaluating non-cognitive skills in the selection process of applicants to the cardiology residency program and fellowships in a cardiovascular center.

Histopathological findings of inflammatory activity in patients with subclinical carditis / Achados histopatológicos de atividade inflamatória em pacientes com cardite subclínica

In patients with Chronic Rheumatic Carditis, active carditis is an often underdiagnosed condition. Rheumatic attacks promote the aggravation of existing lesions, leading to a deterioration of the patient's clinical condition. Thus, reducing the morbidity and mortality of the disease depends, in part, on controlling relapses through secondary prophylaxis. Underdiagnosis is due in part to the occurrence of subclinical rheumatic attacks. This study was carried out with data from patients who were diagnosed with Chronic Rheumatic Carditis and who underwent cardiac surgery for valve replacement or repair, without clinical or laboratory evidence of rheumatic outbreak. A fragment of myocardium was sent for histopathological analysis. Data on the frequency of histopathological alterations compatible with a rheumatic outbreak were analyzed. After analysis, 80% of patients showed changes compatible with inflammatory activity. Of these, 87.5% had lymphocytic infiltrate; 25% had Aschoff's nodules. The most frequent histopathological findings of chronic disease were myocardial hypertrophy in 56.7% of patients and fibrosis in 53.3% (AU).

Nos pacientes com Cardite Reumática Crônica, a cardite em atividade é uma condição frequentemente subdiagnos-ticada. Os surtos reumáticos promovem o agravamento das lesões já existentes, levando a uma deterioração da condição clínica do paciente. Dessa forma a redução da morbimortalidade da doença depende, em parte, do contro-le de recidivas a partir da profilaxia secundária. O subdiagnóstico deve-se em parte a ocorrência de surtos reumáti-cos subclínicos. Este estudo foi realizado com dados dos pacientes que tiveram o diagnóstico de Cardite Reumática Crônica e foram submetidos à cirurgia cardíaca para troca ou plastia valvar, sem evidência clínica ou laboratorial de surto reumático. Um fragmento de miocárdio foi enviado para análise histopatológica. Foram analisados os dados de frequência de alterações histopatológicas compatíveis com surto reumático. Após análises, 80% dos pacientes apresentaram alterações compatíveis com atividade inflamatória. Desses, 87,5% apresentavam infiltrado linfocitá-rio; 25% apresentavam nódulos de Aschoff. Os achados histopatológicos de doença crônica mais frequentes foram hipertrofia miocárdica em 56,7% pacientes e fibrose em 53,3% (AU).

Comorbidities and clinical symptoms can modify myocardial function: a cross-sectional study with PET/CT / Comorbilidades y síntomas clínicos que pueden modificar la función miocárdica: estudio transversal con PET/TC

Abstract Objective: Associating comorbidities and cardiac symptoms that alter myocardial mechanical function could help clinicians to correctly identify at-risk population. Methods: We conducted a functional open population cross-sectional study of patients referred to a positron emission tomography/computed tomography unit in Mexico City for evaluation of myocardial function, perfusion, and coronary circulation. Ischemia was defined as a sum difference score ≥ 2. Association between comorbidities and cardiac symptoms was tested using logistic regression models and trend analysis. We performed an interaction analysis to evaluate the addition of any accompanying symptoms to comorbid conditions on impairment of myocardial function. Results: One thousand two hundred and seventy-three patients were enrolled, 66.1% male, with a mean age of 62.4 (± 12.7) years, 360 (28.7%) with ischemia, 925 (72.7%) with at least one comorbidity, and 676 (53.1%) had at least one associated cardiac symptom. Patients without ischemia, type 2 diabetes, arterial hypertension, and adverse cardiac symptoms were associated with adverse mechanical, perfusion, and coronary flow parameters. We observed a trend of a cumulative number of comorbidities and cardiac symptoms with increased ischemia and decreased coronary flow. Only in decreased left ventricular ejection fraction, we demonstrated an interaction effect between increased comorbidities and adverse symptoms. Conclusion: The high burden of comorbidities and symptoms in our population alters myocardial function regardless of the level of ischemia.

Resumen Objetivo: La asociación de comorbilidades y síntomas cardíacos que alteran la función miocárdica podría ayudar a los médicos a identificar correctamente a poblaciones de riesgo. Métodos: Se realizó un estudio transversal en población abierta de pacientes referidos a una unidad de PET/CT en la Ciudad de México para evaluación de la función miocárdica, perfusión y circulación coronaria. La isquemia se definió como una suma de diferencia de puntuación (SDS) ≥ 2. La asociación entre las comorbilidades y los síntomas cardíacos se fundamentó mediante modelos de regresión logística y análisis de tendencias. Realizamos un análisis de interacción para evaluar la adición de cualquier síntoma acompañante a condiciones comórbidas en el deterioro de la función miocárdica. Resultados: Se incluyeron 1.273 pacientes, 66,1% del sexo masculino, con una edad media de 62,4 (± 12.7) años, 360 (28,7%) con isquemia, 925 (72,7%) con al menos una comorbilidad y 676 (53,1%) con al menos una menos un síntoma cardíaco asociado. En pacientes sin isquemia, la diabetes mellitus tipo 2, la hipertensión arterial y los síntomas cardíacos adversos se asociaron con parámetros mecánicos, de perfusión y de flujo coronario adversos. Se observó una tendencia con el número acumulado de comorbilidades y síntomas cardíacos con aumento de la isquemia y disminución del flujo coronario. Solo en la disminución de la FEVI se demostró un efecto de interacción entre el aumento de las comorbilidades y los síntomas adversos. Conclusión: La alta carga de comorbilidades y síntomas en nuestra población altera la función miocárdica independientemente del nivel de isquemia.

Material and methods: Descriptive study carried out in patients diagnosed with CHD in a second level hospital of the Mexican Social Security Institute (IMSS) in Puebla, Mexico during the period 2016-2017. Records of full-term newborns (NB) up to 14 years of age analyzing sociodemographic variables, type of CHD and short-circuit, presence of associated anomalies, and referral to a third level hospital for surgical treatment were included. Data were collected and analyzed using the SPSS Statistics v25 program. Results: The hospital prevalence of CHD that required referral to the third level hospital for surgical treatment was 6.8% in 2016 and 6.6% in 2017; the median age was 1 year. The 77.2% of CHDs were non-cyanotic, patent ductus arteriosus (PDA) was the most common shunt, and 19.2% had Down syndrome as an associated congenital anomaly. Conclusion: We obtained a similar prevalence to other regions of Mexico, with acyanotic CHD being the most frequent cause of surgical treatments. Timely detection and referral will improve care and quality of life in these patients.

Panorama de la ectasia coronaria en el Instituto Nacional de Cardiología Ignacio Chávez: un estudio transversal / Outlook of coronary ectasia at the National Institute of Cardiology Ignacio Chávez: a cross-sectional study

Resumen Introducción: La ectasia coronaria (EC) es una remodelación patológica con una prevalencia mundial baja. Se define como una dilatación difusa mayor a 1.5 veces el diámetro de los segmentos adyacentes de esta o diferentes arterias coronarias. Objetivo: Documentar las características clínicas y angiográficas, y el tratamiento médico que reciben los pacientes con diagnóstico de EC en el Instituto Nacional de Cardiología (INC). Métodos: Estudio de tipo transversal con diseño no experimental descriptivo, con un muestreo por conveniencia no probabilístico. Resultados: De 69 pacientes que asistieron al INC con diagnóstico de EC la mayor parte eran hombres, con una media de edad de 56 ± 11 años, el factor de riesgo coronario más común en los pacientes con EC fue el tabaquismo, en 40 (58%); se asoció un infarto agudo de miocardio con elevación del segmento ST (IAMCEST) en 45 (65.2%), de localización frecuente en la cara inferior 18 (40%), relacionado con la arteria más afectada, la coronaria derecha 48 (69.6%), seguida de la circunfleja 39 (56.5%). Destaca el uso preferente de la terapia antiplaquetaria dual con anticoagulante (APD+ACO) en 40 (58%) al egreso de cada paciente del INC. Conclusión: La EC es una remodelación patológica no infrecuente en el INC. En este estudio se evidenció que el SCA-IAMCEST es la manifestación más típica de la EC, la coronariografía diagnóstica identificó un Markis tipo 3, por lo que se esperaría una tasa baja de mortalidad y recurrencia de eventos cardiovasculares y a pesar de no existir un consenso sobre la terapia ideal, en el INC se prefiere el tratamiento individualizado, recomendando modificación en el estilo de vida y empleando como tratamiento médico el uso de la triple terapia (APD+ACO) solo al momento de egreso del paciente.

Abstract Introduction: Coronary Ectasia (CE) is a pathological remodeling with a low worldwide prevalence. It is defined as a diffuse dilatation greater than 1.5 times the diameter of the adjacent segments of the same or different coronary arteries. Objective: To document the clinical and angiographic characteristics, and medical treatment at the discharge of patients diagnosed with coronary ectasia who attended the National Institute of Cardiology (INC). Methods: Cross-sectional study with a non-experimental descriptive design, with a non-probabilistic convenience sampling. Results: Of 69 patients who attended the INC with a diagnosis of CD, most were men, with a mean age of 56 + 11 years, the most common coronary risk factor in patients with CE was smoking 58% (40); it was associated mostly with an acute myocardial infarction ST-segment elevation (STEMI) 65.2% (45), of frequent location in the lower face 40% (18), correlated with the most affected artery is the Right Coronary Artery (CD) 69.6% (48), followed by the circumflex (Cx) 56.5% (39). A mean LVEF of 47 + 9.72 was evident within the ventricular function. As well as the preferential use of dual antiplatelet therapy with anticoagulant (DAP + OAC) in 58% (40) at the discharge of each patient from the INC. Conclusion: CE is a not uncommon pathological remodeling in INC. This study showed that STEMI is the most typical manifestation of CE, diagnostic coronary angiography identified a type 3 Markis, so a low rate of mortality and recurrence of cardiovascular events would be expected, and despite the lack of consensus on the ideal therapy, at the INC individualized treatment is preferred, recommending lifestyle changes, and using triple therapy (DAP + OAC) as a medical treatment only at the time of patient discharge.

The Correlation between QRS Dispersion and Coronary Artery Disease Severity in Patients with Non ST Elevation Myocardial Infraction

Non ST elevation myocardial infarction (NSTEMI) has been the subject of numerous studies. Risk stratification is a fundamental element for the management of NSTEMI; therefore, several scores have been established in this direction, particularly prognostic markers derived from the ECG. Aims: The aim of our study is to correlate the dispersion of the QRS with the severity of coronary lesions assessed by the GENSINI score in patients admitted for NSTEMI at the University Hospital of Marrakech. Methods: A retrospective study was conducted in the cardiology department of Mohammed VI university hospital of Marrakech from January 01, 2022 to March 31, 2022. Data was derived from the hospitalization register, including 30 patients (16 women and 14 men). Age ranged from 56 to 74 years with an average of 64.6 ± 9.3. Data was analyzed by SPSS, the level of significance set at p <0.05. Results: We found, in our study, a highly significant positive correlation between QRS dispersion (considered important if >20 ms) and admission heart rate (p=0.003) as well as the level of ultrasensitive troponins (p=0.003). There is also a very significant correlation between QRS dispersion and corrected QT interval (p=0.005), Moreover, we concluded that in patients admitted for NSTEMI, the greater the dispersion of the QRS, the higher the score of GENSINI (p<0.0001). Conclusion: The dispersion of the QRS is a simple marker on the ECG that can have a predictive value in different clinical contexts, particularly in acute ischemic heart disease. Further studies are needed, however, to validate its usefulness in routine practice.

Análisis de la heterogeneidad en revisiones sistemáticas de cardiología publicadas entre 2000-2005 y 2011-2016 / Analysis of heterogeneity in cardiology systematic reviews published be-tween 2000-2005 and 2011-2016 / Análise da heterogeneidade em revisões sistemáticas de cardiologia publicadas entre 2000-2005 e 2011-2016

Introducción: la cardiología es una de las especialidades médicas que cuenta con más revisiones sistemáticas y metanálisis. Estudiar la metodología de las revisiones y anali­zar su heterogeneidad estadística es fundamental para garantizar su validez científica. Objetivo: describir la comparación de medidas de asociación, modelos estadísticos y grado de heterogeneidad en metanálisis de revisiones sistemáticas de intervenciones farmacológicas en cardiología, publicadas entre 2000-2005 y 2011-2016. Metodología: estudio analítico basado en la descripción y comparación de métodos estadísticos de revisiones sistemáticas de intervenciones farmacológicas en cardiología, publicadas en la biblioteca Cochrane. Para las variables cualitativas se estimaron frecuen­cias absolutas y relativas, mientras que para las cuantitativas se determinaron medias y desviaciones estándar, o medianas y rangos intercuartílicos, según su distribución. Para establecer la diferencia de medias se realizó la prueba t de Student y para la diferencia de proporciones el Chi cuadrado. Resultados: se incluyeron 54 revisiones sistemáticas, con un total de 1053 metanálisis, 6 revisiones con 240 metanálisis entre 2000-2005 y 48 revisiones con 813 metanálisis entre 2011-2016. La mayoría de metanálisis utilizaron el tratamiento estándar como grupo de comparación (56.6%), midieron desenlaces cualitativos nominales (86.3%), determinaron riesgos relativos (63.3%) y aplicaron modelos de efectos fijos (57.8%). En 2011-2016 se encontró una media del Índice de Higgins 17.5 menor que en 2000-2005 (p<0.05). Conclusión: se evidenció una disminución de la heterogeneidad estadística y un aumento en la implementación de modelos de efectos aleatorios, lo que da cuenta de una mayor rigurosidad a la hora de demostrar resultados verdaderamente significativos.

Introduction: cardiology is one of the medical specialties with the most systematic reviews and meta-analyses. Studying the methodology of the reviews and analyzing their statistical heterogeneity is essential to guarantee their scientific validity. Objective: to describe the comparison of association measures, statistical models and degree of heterogeneity in meta-analyses of systematic reviews of pharmacological interventions in cardiology, published between 2000-2005 and 2011-2016. Methodology: analytical study based on the description and comparison of statistical methods of systematic reviews of pharmacological interventions in cardiology, published in the Cochrane library. For the qualitative variables, absolute and relative frequencies were estimated, while for the quantitative ones, means and standard deviations, or medians and interquartile ranges, were determined, depending on their distribution. The Student's t test was used to establish the difference in means and the Chi square for the difference in proportions. Results: 54 systematic reviews were included, with a total of 1.053 meta-analyses, 6 reviews with 240 meta-analyses between 2000-2005, and 48 reviews with 813 meta-analyses between 2011-2016. Most meta-analyses used standard treatment as the comparison group (56.6%), measured nominal qualitative outcomes (86.3%), determined relative risks (63.3%), and applied fixed-effect models (57.8%). In the 2011-2016 period, an average of the Higgins Index was found to be 17.5 lower than in the 2000-2005 (p<0.05). Conclusion: there was evidence of a decrease in statistical heterogeneity and an increase in the implementation of random effects models, which accounts for greater rigor when it comes to demonstrating truly significant results.

Objetivo: descrever a comparação de medidas de associação, modelos estatísticos e grau de heterogeneidade em metanálises de revisões sistemáticas de intervenções farmacológicas em cardiologia, publicadas entre 2000-2005 e 2011-2016. Metodologia: estudo analítico baseado na descrição e comparação de métodos estatísticos de revisões sistemáticas de intervenções farmacológicas em cardiologia, publicadas na biblioteca Cochrane. Para as variáveis qualitativas foram estimadas frequências absolutas e relativas, enquanto para as quantitativas foram determinadas médias e desvios padrão, ou medianas e intervalos interquartis, dependendo de sua distribuição. O teste t de Student foi utilizado para estabelecer a diferença de médias e o qui-quadrado para a diferença de proporções. Resultados: foram incluídas 54 revisões sistemáticas, com um total de 1053 meta-análises, 6 revisões com 240 meta-análises entre 2000-2005 e 48 revisões com 813 meta-análises entre 2011-2016. A maioria das metanálises usou tratamento padrão como grupo de comparação (56.6%), mediu resultados qualitativos nominais (86.3%), determinou riscos relativos (63.3%) e aplicou modelos de efeito fixo (57.8%). Em 2011-2016, a média do Índice de Higgins foi 17.5 menor do que em 2000-2005 (p<0.05). Conclusão: evidenciou-se uma diminuição da heterogeneidade estatística e um aumento da implementação de modelos de efeitos aleatórios, o que confere maior rigor na demonstração de resultados verdadeiramente significativos.

Self-care behavior among patients with heart failure: relationship between sociodemographic and clinical variables / Comportamiento de autocuidado de pacientes con insuficiencia cardíaca: relación con variables sociodemográficas y clínicas / Comportamento de autocuidado de pacientes com insuficiência cardíaca: relação com variáveis sociodemográficas e clínicas

ABSTRACT Objective: to assess self-care behavior and its relationship with the sociodemographic and clinical variables of patients with heart failure. Method: a cross-sectional and correlational study was conducted in a cardiomyopathy outpatient clinic in São Paulo, SP, Brazil. Data were collected between 2018 and 2020. The sample consisted of patients with heart failure without visual, auditory, or cognitive deficits. Self-care behavior was assessed using the European Heart Failure Self-care Behavior Scale. Sociodemographic and clinical variables were selected through a literature review. The Spearman's correlation coefficient and the Mann-Whitney test were used for data analysis. Factors presenting p≤0.10 and the variables of clinical interest were included in the multiple analysis, and p-values ≤ 0.05 were considered significant. Results: 340 patients with a mean self-care score of 24.7 were analyzed. Those taking more medications and adhering to the pharmacological treatment tended to present improved self-care (p≤0.001). In contrast, patients without a partner (p=0.022), with a sedentary lifestyle (p<0.001), or employed (p<0.001) tended to present worse self-care scores. Conclusion: The factors related to self-care behavior were adherence to pharmacological treatment, the number of medications taken, marital status, employment, and sedentary lifestyle.

Effects of sacubitril valsartan sodium on vascular sclerosis and ventricular remodeling in patients with ischemic cardiomyopathical coronary heart disease / 中国医师进修杂志

Objective:To study the effects of sacubitril valsartan sodium on vascular sclerosis and ventricular remodeling in patients with ischemic cardiomyopathical coronary heart disease.Methods:A prospective research method was adopted. One hundred and eighty-six patients with coronary heart disease who were treated in Hangzhou Ninth People′s Hospital from January to December 2021 were selected and divided into control group and observation group by random digits table method, with 93 cases in each group. The control group adopted routine treatment method of aspirin + metoprolol + nitroglycerin + captopril according to the guideline, while the observation group was additionally treated with sacubitril valsartan sodium on the basis of the control group. The clinical efficacy, vascular endothelial function and hardness, cardiac function, ventricular remodeling and adverse reactions were compared between the two groups.Results:The total effective rate of treatment in observation group was significantly higher than that in control group: 96.77%(90/93) vs. 87.10%(81/93), and there was statistical difference ( P<0.05). After treatment, the brachial artery flow-mediated dilation in observation group was significantly higher than that in control group: (14.46 ± 2.80)% vs. (13.09 ± 2.74)%, the level of endothelin-1 was significantly lower than that in control group: (73.32 ± 9.63) ng/L vs. (77.47 ± 10.35) ng/L, and there were statistical differences ( P<0.05). After treatment, the left ventricular ejection fraction (LVEF) in observation group was significantly higher than that in control group: (50.87 ± 3.52)% vs. (49.72 ± 3.71)%, the left ventricular end-systolic diameter, left ventricular end-diastolic diameter and ventricular remodeling indicators of interventricular septal thickness and left ventricular mass index were significantly lower than those in control group: (38.26 ± 5.18) mm vs. (40.05 ± 5.20) mm, (50.49 ± 4.33) mm vs. (52.08 ± 4.25) mm, (8.95 ± 0.39) mm vs. (9.08 ± 0.41) mm, (118.49 ± 9.58) g/m 2 vs. (121.58 ± 9.62) g/m 2, and there were statistical differences ( P<0.05). There were no statistical differences in the levels of total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol after treatment between the two groups ( P>0.05). There were no statistical differences in the incidences of adverse reactions between the two groups ( P>0.05). Conclusions:Sacubitril valsartan sodium has a good clinical efficacy in the treatment of coronary heart disease, and it can improve cardiac function and vascular sclerosis and reverse ventricular remodeling. In addition, it has no significant adverse reactions and is conducive to disease recovery.

Syndrome differentiation and treatment of coronary heart disease combined with anxiety and depression from stages of phlegm, blood stasis, and toxic pathogen based on theory of "coexistence of diseases and depression syndromes" / 中国中药杂志

Depression syndromes(anxiety and depression), as typical psychological disorders, often coexist with and mutually influence coronary heart disease(CHD). They constitute a psycho-cardiology disease involving both the blood vessels of the heart and the spirit of the heart. Based on the theory of "coexistence of diseases and depression syndromes", it was proposed that CHD and depression syndromes coexisted independently and were causally related. The factors of depression syndromes go through the entire course of CHD and have different causal relationships at different stages, leading to a pathogenic process of "depression causing disease" or "disease causing depression". In the chronic latent period, phlegm predominates, with depression leading to the production of phlegm. Phlegm accumulation and Qi stagnation initiate a mutual damage process of psycho-cardiology, marking the onset of the disease. In the pathological development period, blood stasis becomes predominant. Depression leads to blood stasis, which further obstructs Qi circulation, accelerating disease progression. In the acute attack period, toxicity becomes crucial. Depression transforms into toxicity, damaging Qi and blood, disturbing the balance of the mind, and inducing a sudden and severe exacerbation of the disease. Based on this, the approach of treating phlegm and depression together, treating blood stasis and depression together, and treating toxicity and depression together by stages was established. Research has found that this approach can simultaneously improve organic damage and emotional disorders, and also has a regulating effect on micro-level syndrome indicators, achieving harmonization of psycho-cardiology in the treatment.
