Is Hypertension a Predictor of Mortality in People Living With HIV/AIDS?

Gustavo Eduardo Fante et al. Pedro Antonio Pagote Dall’Omo Karina Bobato do Valle Arcelio Benetoli … Jean Fernando Sandeski Zuber Camila Marineli Martins Erildo Vicente Muller

Abstract

Background:

Hypertension is a chronic non-communicable disease that increases cardiovascular risk and significantly contributes to mortality. It is one of the most prevalent conditions among people living with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS).

Objectives:

The objective of this study was to investigate hypertension as a predictor of mortality in people living with HIV/AIDS, analyzing the association of prior diagnosis of hypertension with morbidity and mortality in this population.

Methods:

This retrospective cohort study evaluated the medical records of 1207 patients receiving treatment at the Specialized Care Service (SAE) of a city in the state of Paraná over 264 months.

Results:

Among patients diagnosed with HIV/AIDS, 13.1% had hypertension. During the analyzed period, 52 deaths were recorded (4.31%), 30.77% of which occurred among patients with hypertension (p = 0.0002). Lower survival was observed among patients with hypertension (p < 0.0001), and mortality was significantly higher among women with hypertension (p < 0.0001). The hazard ratio (HR) for the general population was 3.1 (95% confidence interval [CI]: 1.7–5.6), with an HR of 1.7 for men (95% CI: 0.7–3.7) and 8.2 for women (95% CI: 3.1–21.6).

Conclusions:

Hypertension was a significant predictor of mortality in people living with HIV/AIDS, with a particularly strong impact among women.

Use of Extracorporeal Membrane Oxygenation in Adult Patients During Cardiac Arrest

Cibelle Alves et al. Sarah Queiroz Pimentel Francine Jomara Lopes

Abstract

Background

Integrated extracorporeal membrane oxygenation (ECMO) in the treatment of cardiopulmonary resuscitation (CPR) is described as extracorporeal cardiopulmonary resuscitation (ECPR). It is used to ensure recovery of cardiac output when it is not possible to obtain sustained return of spontaneous circulation (ROSC) through conventional CPR methods. The comparison between ECPR and conventional CPR is a dilemma that has been frequently discussed.

Objective

To identify in the literature the use of ECMO in adult patients during cardiac arrest (CA) in and pre- and in-hospital settings.

Method

This is an integrative review using the following guiding question: What is the evidence in the literature on the use of ECMO in adult patients with cardiorespiratory arrest in the pre- and in-hospital setting? It consists of primary studies, published in full and available in Portuguese, English, and Spanish.

Results

The search identified 559 publications in the literature, of which 13 were articles read in full, after applying the inclusion criteria. Of these, 3 were disregarded due to unavailability in the complete format; 7 did not respond to the guiding question, and 3 studies were included. The studies were analyzed according to the 2020 version of the PRISMA Model.

Conclusion

ECPR is a practice adopted when CPR is refractory to conventional life support and concomitantly with this management. There are no significant differences in the rate of favorable neurological outcomes when comparing the pre- and in-hospital scenarios. In short, the development of institutional protocols with selection and exclusion criteria for ECPR is considered relevant.

Cardiorespiratory Optimal Point: A New Kid in the Block or an Established Star?

Miguel Mendes

Summary

COP researchers have already conducted very important research that must be expanded, including larger and more diverse and better defined populations, with patients around the world, different cardiovascular and non-cardiovascular diseases, tests using a treadmill (more experience with treadmill CPET is needed), and evaluation of the prognostic values of sub-maximal parameters, such as COP and eventually VO ₂ at VT1, versus the maximal parameters, such as pVO ₂ , VE/VCO ₂ slope, and OUES.

A clear answer is needed: Is the information obtained from a submaximal CPET enough, or should it be considered only as an alternative when it is not possible to perform a maximal CPET or when peak VO ₂ was not reached?

Congenital Heart Disesase: A Retrospective Analysis from a Tertiary Referral Centre in Portugal

Diogo Faim et al. Joaquim Tiago Rui Castelo Andreia Francisco … Rosa Alves António Pires

Abstract

Background:

Congenital heart disease is the leading cause of mortality among all congenital malformations.

Objectives:

To evaluate the incidence of congenital heart diseases in a central maternity hospital in Portugal from January 2003 to December 2018 and to determine survival in the first year of life.

Methods:

Retrospective analysis of newborns diagnosed with congenital heart diseases within 72 hours after birth. Malformations were divided according to pathophysiology. Cumulative survival analysis was performed by the Kaplan-Meier test. Stastical significance was set at p <0.05.

Results:

A total of 297 newborns with cardiac malformation was recorded among 47,198 live births (incidence of 6:1000), 16% associated with extra-cardiac disease. The most frequent congenital heart diseases were left-to-right shunt lesions (n = 216), followed by cyanotic (n = 41), acyanotic obstructive (n = 31) and miscellaneous (n = 9). Seventy (24%) patients had prenatal diagnosis, 88% of them cyanotic defects, and a positive association was found between prenatal diagnosis and mortality (p <0.001). Coarctation of the aorta was associated with gestational diabetes (p = 0.014). Atrial septal defect was more common in females (p = 0.02). Mortality rate due to heart disease was 3.4%. Patients with cyanotic disease, 99%, 97%, 97%, respectively, for patients with left-to-right shunt lesions, and 97%, 97%,97% for those with obstructive lesion cases.

Conclusion:

The incidence of congenital heart disease was 6:1000, mostly left-to-right shunt lesions. Heart disease accounted for only half of deaths, and cyanotic diseases have a high nonspecific mortality rate.

Some predictors of cardiovascular mortality among the elderly population of Botucatu (SP)

Tania Ruiz et al. Mirela D. Sanchís Ana Maria Fioravante Xavier C. Piqué

OBJECTIVE: To detect factors associated with cardiovascular mortality in the elderly of Botucatu. METHODS: We evaluated 29 variables of interest in a cohort of patients aged ³60 using data from a survey conducted between 1983/84. The elderly cohort was analyzed in 1992 to detect the occurrence of cardiovascular deaths. Survival analysis was performed using the Kaplan-Meier method, the log-rank test, and Cox regression analysis. Three models were adapted for each group of variables, and a final model was chosen from those variables selected from each group. RESULTS: We identified predictor for cardiovascular death according to age for elderly males not supporting the family, not possessing a vehicle, and previous cardiovascular disease. In elderly females, the predictor variables were previous cardiovascular disease and diabetes mellitus. CONCLUSION: Socioeconomic indicators (family heading and vehicle ownerrship) may be added to well stabilished medical factors (diabete mellitus and hypertension to select target groups for programs intended to reduce deaths due to cardiovascular diseases in elderly people.
