Since the discovery of right ventricular infarction, interest in the characteristics of the right ventricle has been increasing. Right ventricular function is now known to be a predictor of mortality in different settings. The right ventricle is a low-pressure, high-compliance, high-volume chamber. To carry out its normal function, it is coupled to the pulmonary circulation and the left ventricle. In the face of acute changes in pressure, volume overload and ischemia, it dilates to adapt to its new load. Its manifestation may be ventricular dysfunction and/ or failure that will progress to cardiogenic shock due to right ventricular involvement. Various entities may be the cause of acute dysfunction: right ventricular infarction (alterations in contractility due to ischemia) and high-risk pulmonary thromboembolism (increased afterload). Both share a similar ventricular pathophysiology and high mortality without treatment. Understanding anatomy and physiology, dysfunction and acute ventricular failure are important to define a convenient diagnosis and treatment oriented towards pathophysiology. In this first part, the anatomy and physiology, acute right ventricular dysfunction/failure and cardiogenic shock are taken into consideration, from the perspective of these two entities. In another paper, treatment aimed at cardiogenic shock due to right ventricular involvement will be reviewed. [ABSTRACT FROM AUTHOR]

The Código Infarto (Infarction Code) strategy is part of the comprehensive care program "A Todo Corazón" (To All Heart), whose aim is to reinforce the prevention and health care of cardiovascular diseases. Mexico faces a big challenge, since it is the country with greater mortality secondary to acute myocardial infarction (AMI) in the first 30 days in patients of 45 years or older (28% compared with 7.9% of the average). In addition, Mexico's population has a high prevalence of risk factors (hypertension, diabetes, tobacco use, dyslipidemias, overweight, and obesity). It is for these reasons that 18 months ago the Instituto Mexicano del Seguro Social (IMSS) implemented the first care protocol for patients with AMI, called Código Infarto, whose main aim is to guarantee the diagnosis and treatment of patients with AMI, so that they can receive, once they are admitted at IMSS emergency rooms, primary angioplasty in less than 90 minutes, or fibrinolytic therapy in less than 30 minutes. The quality focus in the Código Infarto strategy has six main dimensions: security, effectiveness, its focus on the patient, opportune, efficient, and [it offers] equitable [treatment]. The implementation of Código Infarto in IMSS is the first institutional strategy to face the leading cause of death in our country and it has produced up until now very encouraging results.

Introduction. Coronary bypass grafting proved to reduce mortality in patients with extensive vascular disease. Patients undergoing this procedure using an extracorporeal circulation pump have a perioperative mortality of 2%. The incidence of complications such as myocardial infraction, cerebrovascular disease and acute kidney injury ranges from 5 to 7%. The presence of systemic inflammatory response syndrome (SIRS) may be a prognostic and diagnostic marker of postsurgical complications Material y Methods. This is a prospective and descriptive study. It used association tests between systemic inflammatory response syndrome and postsurgical complications arising from coronary bypass grafting in Hospital Christus Muguerza in Monterrey, Nuevo León, Mexico, from March to October 2014. Results. A total of 17 patients were included. Patients with one SIRS criterion registered one complication. The group of patients with four criteria registered four complications. The total number of days patients remained in UCI had a correlation coefficient of 0.71 with an internal consistence of 0.83 (p=.00042) according to the SIRS criteria. Discussion. Revascularization surgery causes great stress to the patients and it is reflected by systemic inflammatory response syndrome. With data obtained from this study we can infer that according to the patient's response we may estimate the number of ICU days and the risk of postsurgical complications. Nevertheless, due to the short duration of this sturdy, our results are not statistically significant. Therefore we may not assure a numerical value to the existent correlation or risk.

Introduction: This research protocol is intended to interfere with the family and to determine the effectiveness of the model of nursing care for the family of patient with acute infarction myocardium (AMI) in the intensive care unit (ICU). Materials and Methods: Descriptive study of family intervention Results and Discussion: 100% Of families responded affirmatively to the family nurse them informed about the care the family according to needs identified, established a plan of action in family same which met and it is interested for that as far as possible agreeable stay in the family. Conclusions: The results of this investigation of intervention with AMI in the ICU patient families brings results that support the importance of implementing a care model of nursing family in these units.
