An Intersectoral Approach to Hypertension Care: Solutions for Improving Blood Pressure Control in São Paulo, Brazil.

BACKGROUND: Hypertension is the leading risk factor for cardiovascular diseases (CVDs) and a major public health issue worldwide. In Brazil, it affects approximately 52.5% of the adult population. We describe the solutions package and the impact of a population health initiative in São Paulo city, following the CARDIO4Cities approach for the management of cardiovascular risk. METHODS: Using a design thinking approach, interventions were developed with a coalition of local and international stakeholders to address needs of patients, healthcare professionals, and the health system. The resulting solution package was checked to comply with guidelines for non-communicable disease and hypertension management. Clinical impact was measured by extracting the hypertension cascade of care-monitored, diagnosis, treatment, and control-from medical records. RESULTS: Under the leadership of the municipal health authorities, nine solutions were piloted and scaled across the city. Solutions conform with local and international best-practices. Between October 2017 and December 2021, 11,406 patient records were analyzed. Results showed a 40% increase in monitored patients (patients with at least one blood pressure, BP, measurement); reduced proportions of patients diagnosed among those with available BP measurements (72%-53%) and treated among diagnosed (93%-85%); and an improvement in controlled patients among those receiving treatment (16%-27%). CONCLUSIONS: The solution package described in this study was correlated with increased BP control. The implementation methodology and results add to the body of real-world evidence supporting population health implementation science in Brazil and beyond.

Cost-utility analysis of diagnostic methods for arterial hypertension in primary care for Brazil: ABPM vs. OBPM vs. HBPM.

INTRODUCTION: Arterial hypertension (AH) is diagnosed using three methods: office blood pressure measurement (OBPM), home blood pressure monitoring (HBPM), and ambulatory blood pressure monitoring (ABPM). No economic studies have evaluated the impact of incorporating these strategies for AH diagnosis into the Brazilian public health system. METHODS: A Markov model was created to evaluate the costs associated with AH diagnosis using the ABPM, HBPM, and OBPM. Patients were entered into the model with SBP ≥ 130 mmHg or DBP ≥ 85 mmHg obtained using OBPM. The model was based on cost, quality adjusted life-years (QALYs), and incremental costs per QALY. In the economic analysis, the costs were calculated from the perspective of the payer of the Brazilian public health system. RESULTS: In the cost-utility analysis of the three methods, ABPM was the most cost-effective strategy compared to HBPM and OBPM in all groups over 35 years of age. Compared with OBPM, ABPM was a cost-effective strategy, as it presented higher costs in all scenarios, but with better QALYs. Compared to HBPM, ABPM was the dominant strategy for all age groups, presenting lower costs and higher QALYs. When comparing HBPM with OBPM, the results were similar to those described for ABPM (i.e. it was a cost-effective strategy). CONCLUSION: With a willingness-to-pay threshold of R$35 000 per QALY gained, both ABPM and HBPM are cost-effective methods compared with OBPM in all scenarios. In Brazilian healthcare facilities that currently diagnose AH using OBPM, both ABPM and HBPM may be more cost-effective choices.

Synchronization and bifurcation in an economic model.

We study the synchronization of two coupled idealized economies. In the present work, we consider a recently developed economic system that shows a richness of dynamical behavior. By means of the Lyapunov exponents, we analyze that there is overly complex behavior in the transitions in the dynamics of an isolated economy, oscillating between chaotic attractors and limit cycles. Then, for two coupled economies, we analyze the synchronization states for the space of all control parameters as a function of the network coupling parameter. Interestingly, we have evidenced that there is a broad region of fully synchronized states and as we increase the coupling, some phenomena such as a smooth and intermittent loss in synchronization emerge. In the same way, we observe phase synchronization for one of the control parameters. Ultimately, in order to confirm this loss of synchronization, we inspect the stability of synchronized states through the master stability function method for some control parameters. Here, we corroborate what was previously observed, the unexpected vast range of control parameter values of instability corresponding to desynchronization.

Treinamento de Não-Cardiologistas pode Melhorar os Resultados do Tratamento de Infarto Agudo do Miocárdio com Supra de ST / Training Non-Cardiologists Could Improve the Treatment Results of ST Elevation Myocardial Infarction

Resumo Fundamento De acordo com a Organização Mundial da Saúde, países emergentes terão um crescimento considerável no número de ataques cardíacos e mortes relacionadas. Um dos principais problemas médicos no Brasil é a mortalidade causada por infarto agudo do miocárdio com supra de ST (IAMCSST). A Sociedade de Cardiologia do Estado de São Paulo nunca treinou não-cardiologistas para atendimentos de emergência. Os pacientes normalmente buscam ajuda em prontos-socorros, em vez de chamar a ambulância. Objetivo Nosso objetivo foi reduzir as taxas de mortalidade hospitalar causada por infarto agudo do miocárdio ao treinar profissionais da emergência na cidade de São Paulo. Métodos Utilizamos um programa de treinamento para as equipes de cinco hospitais com > 100 pacientes internados com IAMCSST por ano, e pelo menos 15% de mortes hospitalares relacionadas ao IAMCSST. Realizamos treinamentos online, organizamos de dois a quatro eventos para até 400 participantes, fizemos folders e panfletos informativos. A análise estatística utilizou o teste para comparação de duas proporções, com p <0,05. Resultados Quase 200 médicos e 350 enfermeiros participaram de pelo menos um treinamento de maio de 2010 até dezembro de 2013. Inicialmente, muitos médicos da emergência não reconheciam um infarto agudo do miocárdio no eletrocardiograma, mas a tele-ecocardiografia é usada em alguns departamentos da emergência para determinar o diagnóstico. A taxa de mortalidade nos cinco hospitais caiu de 25,6%, em 2009, para 18,2%, em 2010 (p=0,005). Depois da conclusão do período de treinamento, as mortes relacionadas ao IAMCSST em todos os hospitais públicos de São Paulo diminuíram de 14,31%, em 2009, para 11,25%, em 2014 (p<0,0001). Conclusão Mesmo programas simplificados de treinamento de pessoal da emergência pode reduzir muito as taxas de morte por infarto agudo do miocárdio em países em desenvolvimento.

Abstract Background According to the World Health Organization, emerging countries will have an enormous growth in the number of heart attacks and related deaths. The main medical issue in Brazil is mortality caused by acute ST elevation myocardial infarction (STEMI). The Society of Cardiology in the State of São Paulo has never trained non-cardiologists as emergency personnel. Patients usually seek help from emergency departments instead of calling for an ambulance. Objectives We aimed at reducing in-hospital death rates from acute myocardial infarction by training emergency personnel in the city of Sao Paulo. Methods We used a training program for the personnel of five hospitals with >100 patients admitted with STEMI per year, and at least 15% in-hospital STEMI-associated mortality rate. We performed internet training, biannual-quarterly symposia for up to 400 participants, informative folders and handouts. Statistical analysis used the two proportion comparison test with p <0.05. Results Nearly 200 physicians and 350 nurses attended at least one training from May 2010 to December 2013. Initially, many emergency physicians could not recognize an acute myocardial infarction on the electrocardiogram, but tele-electrocardiography is used in some emergency departments to determine the diagnosis. The death rate in the five hospitals decreased from 25.6%, in 2009, to 18.2%, in 2010 (p=0.005). After the entire period of training, the STEMI-associated death rate in all public hospitals of São Paulo decreased from 14.31%, in 2009, to 11.25%, in 2014 (p<0.0001). Conclusion Even simple training programs for emergency personnel can greatly reduce acute myocardial infarction death rates in undeveloped countries.

Influence of gender on the risk of death and adverse events in patients with acute myocardial infarction undergoing pharmacoinvasive strategy.

Pharmacoinvasive treatment is an acceptable alternative for patients with ST-segment elevation myocardial infarction (STEMI) in developing countries. The present study evaluated the influence of gender on the risks of death and major adverse cardiovascular events (MACE) in this population. Seven municipal emergency rooms and the Emergency Mobile Healthcare Service in São Paulo treated STEMI patients with tenecteplase. The patients were subsequently transferred to a tertiary teaching hospital for early (<24 h) coronary angiography. A total of 469 patients were evaluated [329 men (70.1%)]. Compared to men, women had more advanced age (60.2 ± 12.3 vs. 56.5 ± 11 years; p = 0.002); lower body mass index (BMI; 25.85 ± 5.07 vs. 27.04 ± 4.26 kg/m2; p = 0.009); higher rates of hypertension (70.7 vs. 59.3%, p = 0.02); higher incidence of hypothyroidism (20.0 vs. 5.5%; p < 0.001), chronic renal failure (10.0 vs. 8.8%; p = 0.68), peripheral vascular disease (PVD; 19.3 vs. 4.3%; p = 0.03), and previous history of stroke (6.4 vs. 1.3%; p = 0.13); and higher thrombolysis in myocardial infarction risk scores (40.0 vs. 23.7%; p < 0.001). The overall in-hospital mortality and MACE rates for women versus men were 9.3 versus 4.9% (p = 0.07) and 12.9 versus 7.9% (p = 0.09), respectively. By multivariate analysis, diabetes (OR 4.15; 95% CI 1.86-9.25; p = 0.001), previous stroke (OR 4.81; 95% CI 1.49-15.52; p = 0.009), and hypothyroidism (OR 3.75; 95% CI 1.44-9.81; p = 0.007), were independent predictors of mortality, whereas diabetes (OR 2.05; 95% CI 1.03-4.06; p = 0.04), PVD (OR 2.38; 95% CI 0.88-6.43; p = 0.08), were predictors of MACE. In STEMI patients undergoing pharmacoinvasive strategy, mortality and MACE rates were twice as high in women; however, this was due to a higher prevalence of risk factors and not gender itself.

Predictors of in-hospital mortality in patients with ST-segment elevation myocardial infarction undergoing pharmacoinvasive treatment

OBJECTIVES: To identify predictors of in-hospital mortality in patients with acute myocardial infarction undergoing pharmacoinvasive treatment. METHODS: This was an observational, prospective study that included 398 patients admitted to a tertiary center for percutaneous coronary intervention within 3 to 24 hours after thrombolysis with tenecteplase. ClinicalTrials.gov: NCT01791764 RESULTS: The overall in-hospital mortality rate was 5.8%. Compared with patients who survived, patients who died were more likely to be older, have higher rates of diabetes and chronic renal failure, have a lower left ventricular ejection fraction, and demonstrate more evidence of heart failure (Killip class III or IV). Patients who died had significantly lower rates of successful thrombolysis (39% vs. 68%; p = 0.005) and final myocardial blush grade 3 (13.0% vs. 61.9%; p<0.0001). Based on the multivariate analysis, the Global Registry of Acute Coronary Events score (odds ratio 1.05, 95% confidence interval (CI) 1.02-1.09; p = 0.001), left ventricular ejection fraction (odds ratio 0.9, 95% CI 0.89-0.97; p = 0.001), and final myocardial blush grade of 0-2 (odds ratio 8.85, 95% CI 1.34-58.57; p = 0.02) were independent predictors of mortality. CONCLUSIONS: In this prospective study that evaluated patients with ST-segment elevation myocardial infarction treated by a pharmacoinvasive strategy, the in-hospital mortality rate was 5.8%. The Global Registry of Acute Coronary Events score, left ventricular ejection fraction, and myocardial blush were independent predictors of mortality in this high-risk group of acute coronary syndrome patients. .
