Cardiovascular Complications in Patients with Heart Failure and COVID-19: CARDIO COVID 19-20 Registry.

Since early 2020, different studies have shown an increased prevalence of COVID-19 and poorer prognosis in older adults with cardiovascular comorbidities. This study aimed to assess the impact of heart failure (HF) on cardiovascular complications, intensive care unit (ICU) admissions, and in-hospital mortality in patients hospitalized with COVID-19. The CARDIO COVID 19-20 registry includes 3260 hospitalized patients with a COVID-19 serological diagnosis between May 2020 and June 2021 from Latin American countries. A history of HF was identified in 182 patients (5.6%). In patients with and without previous HF, the incidence of supraventricular arrhythmia was 16.5% vs. 6.3%, respectively (p = 0.001), and that of acute coronary syndrome was 7.1% vs. 2.7%, respectively (p = 0.001). Patients with a history of HF had higher rates of ICU admission (61.5% vs. 53.1%, respectively; p = 0.031) and in-hospital mortality (41.8% vs. 24.5%, respectively; p = 0.001) than patients without HF. Cardiovascular mortality at discharge (42.1% vs. 18.5%, respectively; p < 0.001) and at 30 days post-discharge (66.7% vs. 18.0%, respectively) was higher for patients with a history of HF than for patients without HF. In patients hospitalized with COVID-19, previous history of HF was associated with a more severe cardiovascular profile, with increased risk of cardiovascular complications, and poor in-hospital and 30-day outcomes.

Salud cardiovascular en habitantes de Atahualpa: características y correlatos / Cardiovascular health status in Atahualpa residents: characteristics and correlates

RESUMEN Las enfermedades vasculares son consideradas como las nuevas epidemias de salud en América Latina debido al aumento en la expectativa de vida y a cambios en el estilo de vida de sus habitantes. El conocimiento del estado de salud cardiovascular (SCV) de estas poblaciones es mandatorio para implementar estrategias costo-efectivas dirigidas a reducir la prevalencia de estas enfermedades en la región. En el Proyecto Atahualpa se ha valorado el estado de SCV de los participantes, utilizando los marcadores de salud propuestos por la Asociación Americana del Corazón. El estudio basal incluyó 616 sujetos libres de enfermedad cerebrovascular y cardiopatía isquémica, con edad ≥40 años. De estos, el 2.1% tuvieron un estado de salud ideal, el 28.1% intermedio y el 69.8% pobre. Los peores marcadores incluyeron presión arterial, glucosa en ayunas e índice de masa corporal. La posibilidad de tener un estado de SCV pobre estuvo aumentada en sujetos ≥60 años y en aquellos con escolaridad primaria. Luego, comparamos el estado de SCV de nuestra población con la de hispanos enrolados en el NOMAS, y encontramos que los residentes de Atahualpa tuvieron mejores marcadores de salud, con excepción de los niveles de glucosa en ayunas. La posibilidad de tener 5-7 marcadores en rango ideal fue más elevada en los residentes de Atahualpa, independientemente de la edad. También realizamos un estudio para valorar la SCV dependiendo del aislamiento social y encontramos que el vivir solo se asoció con un peor estado de SCV. Otros estudios mostraron relación entre ciertas patologías del sueño y un peor estado de SCV. Finalmente, hemos empezado el programa "conoce tus números", el cual sumado a charlas comunitarias, se encuentra dirigido a mejorar la SCV de los residentes de Atahualpa y reducir la incidencia de eventos vasculares en la región.

ABSTRACT Stroke and cardiovascular diseases will be the next epidemics in Latin America due to changes in lifestyle and increased life expectancy. Knowledge of cardiovascular health (CVH) status of the population is mandatory to implement cost-effective strategies directed to reduce the burden of vascular diseases in the region. In the Atahualpa Project, we assessed the CVH status of participants using the metrics proposed by the American Heart Association. The basal study included 616 subjects free of stroke and ischemic heart disease aged ≥40 years. Of these, 2.1% had ideal, 28.1% had intermediate and 69.8% had poor CVH status. Poorest metrics were blood pressure, fasting glucose, and BMI. The odds for having a poor CVH status were increased in persons aged ≥ 60 years and in those with only primary school education. Then, we compared our results with the Hispanic population of the Northern Manhattan Stroke Study (NOMAS), and found that Atahualpa residents had significantly better metrics than those enrolled in the NOMAS, with the exception of fasting glucose levels. Likewise, the odds for having 5 to 7 ideal metrics were also better in Atahualpa residents, irrespective of age. We also conducted a case-control study to assess the CVH status of Atahualpa residents according to their living arrangements, and found that social isolation was associated with a worse CVH status in this population. A couple of studies showed correlation between some sleep related disorders and poor CVH status. We have also started an ongoing program called "known your numbers", which, together with community talks, is directed to improve the CVH status and to reduce the burden of vascular diseases in the region.

Stroke in rural coastal Ecuador: a community-based survey.

Stroke will be South America's next epidemic. Therefore, information on stroke particularities in the region will help to overcome its impact burden. We evaluated prevalence, pattern of sub-types, and pathogenic mechanisms underlying stroke in Atahualpa, a village representative of rural coastal Ecuador. In a three-phase epidemiologic study, suspected cases were detected by a door-to-door survey (Phase I). Then, neurologists evaluated suspected cases and randomly selected negative persons (Phase II), and confirmed patients underwent complementary exams (Phase III). We found 20 stroke patients (mean age 70 years, 60% men) among 642 persons aged ≥40 years. Stroke prevalence was 31.15‰ that increased with age. Most patients had sub-cortical infarctions associated with leukoaraiosis or microbleeds. Hypertensive arteriolopathy was the most likely mechanism underlying strokes (55% patients). Intracranial arterial lesions were found in 47% cases. Extracranial atherosclerotic lesions or cardiac sources of emboli were not found in any case. Comparison of our findings with a previous survey performed in the same village showed an alarming increase in stroke prevalence (from 14.08‰ in 2003 to 31.15‰ in 2012, P = 0.03).

Prevalence of the metabolic syndrome and its correlation with the cardiovascular health status in stroke- and ischemic heart disease-free Ecuadorian natives/mestizos aged ≥40 years living in Atahualpa: a population-based study.

AIMS: Epidemiologic studies assessing cardiovascular risk factors affecting a given population may prove cost-effective to reduce the burden of cardiovascular diseases in the developing world. We evaluated the prevalence of the metabolic syndrome in Atahualpa, a village representative of rural coastal Ecuador. METHODS: Prevalence of the metabolic syndrome and its correlation with the cardiovascular (CVH) status was assessed in a door-to-door survey performed in stroke- and ischemic heart disease-free Ecuadorian native/mestizos aged ≥40 years. RESULTS: The metabolic syndrome was diagnosed in 288 (55.7%) out of 517 persons. Worst individual components were: increased waist circumference (75%), increased fasting glucose (68.1%) and high blood pressure (56.5%). Prevalence of individual components of this condition varied according to age, gender, education, and alcohol intake. However, no differences were found in the odds for having the metabolic syndrome when persons were stratified according to these parameters. A poor CVH status was found in 80.2% persons with and in 55.9% without the metabolic syndrome (p<0.0001). CONCLUSIONS: Prevalence of the metabolic syndrome in Atahualpa is high. Most persons with the metabolic syndrome also have a poor CVH status. However, sizable subsets only have either the metabolic syndrome or a poor CVH status. Stratification of cardiovascular risk according to whether the person has both, one, or none of these two sets of risk factors would be of value to evaluate if the metabolic syndrome, a poor CVH status or the combination of both, better predict the occurrence of vascular outcomes in the long-term follow-up.
