Due to the lack of information on the posology, safety in its use, contraindications, and possible adverse effects, its potential use should have been underestimated at that time for the control of palpitations or as phytochemical agents directed to treat diseases causing this symptom.Sudden cardiac death (SCD) remains a major public health problem. Fortunately, with timely access to early defibrillation and high-quality cardiopulmonary resuscitation, an improvement in survival of victims of sudden death has been demonstrated. Efforts made in different countries to create programs for access to public defibrillation have shown great benefits in counteracting mortality associated with this type of event. Hence, we need more programs (such as cardio protected environments) and changes in public health policies. The objective of this work is to raise awareness among the population and decision makers, of importance establishing this type of programs in our country since there continues to be high mortality associated with SCD in our countrymen.The Physiology Department has played an important role in the development of physiology in Mexico since its beginnings. It was founded by Dr. Arturo Rosenblueth in 1947. Many of the original researchers participated in the formation of the Mexican Society of Physiological Sciences. Researchers belonging to this department have given origin to an important national research center (CINVESTAV) and to numerous groups and departments within the Instituto Nacional de Cardiología such as the Valves department in the basement of the main building of the institute, the department of molecular biology situated in the Anexo de Investigación, and a laboratory in the translational medicine unit. The physiology department has importantly contributed to the development of research in the Instituto Nacional de Cardiología.Sudden cardiac arrest (SCA) and sudden death (SD) continue to be a global public health problem, although the true incidence is unknown, it is estimated that they are responsible for 30% of cardiac origin mortality and may represent 20% of total mortality in adults. Unfortunately, the majority of cases occur in the general population, at the out-of-hospital level, in homes and in people who were not known to have heart disease. Although the majority of SCA victims are considered to be of cardiac origin and more frequent ischemic, it is not possible to rule out other causes only with the clinical diagnosis. Autopsy, histological, and toxicological studies are necessary in all victims of SCA and SD to determine the precise cause of death; when these studies are carried out, causes of non-cardiac origin have been found in up to 40% of victims. The type of arrhythmia responsible for an episode of SCA and SD has changed over the years, now asystole and pulseless electrical activity are detected more frequently than ventricular fibrillation or pulseless ventricular tachycardia. These and other aspects that we consider important in the current behavior of SCA and SD are analyzed in this article.

Heart disease in pregnancy can cause clinical deterioration and maternal-fetal death. It is essential to evaluate risk factors related to complications.

This was a observational, analytical retrospective cohort study with a non-probabilistic convenience sample of pregnant women with congenital or acquired heart disease, corrected or not, or arrhythmias requiring urgent intervention. Patients with mild or moderate valvular regurgitation, mild valvular stenosis, patients without echocardiography or without delivery information were excluded from the study. The outcome was a composite of cardiac, obstetric, and neonatal events. Univariate and multivariate analyzes were performed with logistic regression model and discriminatory capacity with area under the curve and independent analysis of the modified World Health Organization (mWHO) risk classification (mWHO).

A total of 104 patients with an average age of 25 ± 6.5 years presented cardiac events in 13.5%, obstetric in 14.42%, and neonatal in 28.85%. The univariate analysis found an association with New York Heart Association functional status, hypertensive disorders of pregnancy, cesarean delivery, gestational age < 27 weeks, hypoxemia, and mWHO risk. In multivariate only cesarean delivery (odds ratio [OR], 2.68; 95% confidence interval [CI], 1.05-6.86) and gestational age at delivery (OR, 0.39; 95% CI, 0.22-0.67) maintain association with outcomes. The area under the curve for the mWHO risk is 0.75.

There is a high rate of adverse events in patients with heart disease during pregnancy. Gestational age and cesarean delivery behaved as predictors of adverse maternal-fetal outcomes. The mWHO risk classification had an acceptable prediction of adverse outcomes.

Echocardiographic cardiac parameters in the prone position are usually obtained with an esophageal probe. The feasibility of obtaining them by means of a transthoracic approach is unknown.

Estimating the feasibility to obtain parameters of the right ventricle by transthoracic echocardiography in prone position on the subject.

Pilot design of consecutive case series without cardiopulmonary disease. Demographic, vital signs and echocardiographic variables were defined in the ventral initial, prone and ventral final decubitus positions. The data are shown with averages and standard deviations, and frequencies and percentages according to the variable. The differences between the positions were calculated with ANOVA of repeated samples and adjustment of Bonferroni test. Intra-subject variability was obtained by the Bland-Altman procedure and its 95% confidence interval.

We studied 50 subjects, 44 (88%) males, age 30 ± 6 years and body mass index 25.65 ± 2.71 kg/m

. Tricuspid annular plane systolic excursion (TAPSE) and S’-wave were measured 100% of the time. The vital signs and echocardiographic variables according to the position had differences in heart rate (74 ± 9 vs. 77 ± 9 vs. 75 ± 8 beats/min), partial oxygen saturation (94.40 ± 1.70 vs. 96.64 ± 1.79 vs. 95.32 ± 1.36%) and mean systemic blood pressure (65.33 ± 5.38 vs. 67.69 ± 6.31 vs. 65.29 ± 5.62 mmHg); TAPSE (19.74 ± 3.24 vs. 21.60 ± 2.97 vs. selleck kinase inhibitor 19.44 ± 2.84 mm), mean difference (bias) 0 (2, -2.0) and S’-wave (13.52 ± 1.87 vs. 15.02 ± 2.09 vs. 13.46 ± 1.55 cm/s), mean difference (bias) -0.46 (1.21, -2.14) respectively.
