Introduction: Cardiovascular risk calculators (CRC) are not locally validated and calibrated. Surrogate biomarkers of insulin resistance had identified subjects at higher risk of type 2 diabetes and cardiovascular disease., Aim: Establish the frequency of surrogate biomarkers of insulin resistance and their correlation with CRC in primary prevention non-diabetic hypertensive subjects., Methods: This is an observational registry with a prospective consecutive outpatient's sample. The TyG index (TyGi) was calculated as logarithm (Ln) of (fasting triglycerides [mg/dl]×fasting plasma glucose [mg/dl]/2). Patients were stratified according to quartiles of TyGi. Pearson correlation coefficient between TyGi and other relevant variables was evaluated., Results: Four hundred six patients were included with a mean age 55.9±13 years, 231 p (56.9%) males. The mean TyGi was 8.667±0.53. Patients in the highest quartiles of TyGi had significantly higher median difference between expected and actual ASCVD risk (p=0.02), higher frequency of AHA/ACC Pooled Cohort Equation >7.5% (p<0.005), and higher levels of metabolic biomarkers such as median triglyceridemia/HDL cholesterol ratio (TG/HDL) (p<0.0005), glycaemia and A1C (p<0.001 and p=0.02, respectively). The correlation between TyGi and TG/HDL was highly significant (r=0.7076; r 2 =0.5007; p<0.0001), and intermediate with non-HDL cholesterol (r=0.4553, r 2 =0.2073; p<0.0001)., Conclusions: Non-diabetic hypertensive patients with high TyGi, a surrogate biomarker of insulin resistance, had a higher 10-year cardiovascular risk by AHA/ACC Pooled Cohort Equation. TyGi is statistically and significantly correlated with other biomarkers of insulin resistance. TyGi could be a reliable biomarker in clinical practice to stratify cardiovascular risk., (Copyright © 2024 SEH-LELHA. Publicado por Elsevier España, S.L.U. All rights reserved.)

Introduction: During the Coronavirus (COVID-19) pandemic, healthcare providers have overcome difficult experiences such as workplace violence. Nurses are particularly vulnerable to workplace violence. The objective of this study was to characterize violence and aggression against nurses during the COVID-19 pandemic in Latin America., Methods: An electronic cross-sectional survey was conducted in 19 Latin American countries to characterize the frequency and type of violent actions against front-line healthcare providers., Results: Of the original 3544 respondents, 16% were nurses (n = 567). The mean age was 39.7 ± 9.0 years and 79.6% (n = 2821) were women. In total, 69.8% (n = 2474) worked in public hospitals and 81.1% (n = 2874) reported working regularly with COVID-19 patients. Overall, about 68.6% (n = 2431) of nurses experienced at least one episode of workplace aggression during the pandemic. Nurses experienced weekly aggressions more frequently than other healthcare providers (45.5% versus 38.1%, p < .007). Nurses showed a trend of lower reporting rates against the acts of aggression suffered (p = .076). In addition, nurses were more likely to experience negative cognitive symptoms after aggressive acts (33.4% versus 27.8%, p = .028). However, nurses reported considering changing their work tasks less frequently compared to other healthcare providers after an assault event (p = .005)., Conclusion: Workplace violence has been a frequent problem for all healthcare providers during COVID-19 pandemic in Latin America. Nurses were a particularly vulnerable subgroup, with higher rates of aggressions and cognitive symptoms and lower rate of complaints than other healthcare providers who suffered from workplace violence. It is imperative to develop strategies to protect this vulnerable group from aggressions during their tasks., (© 2023 John Wiley & Sons Ltd.)

Hypertension is a major risk factor for cardiovascular disease and the leading cause of death in Colombia. While the rate of hypertension awareness in Colombia is generally high, rates of treatment initiation, adherence, and blood pressure (BP) control are suboptimal. Major international hypertension guidelines recommend starting treatment with a combination of antihypertensive agents, and the use of a single-pill combination (SPC) to maximize adherence. In contrast, Colombian hypertension guidelines recommend starting treatment with diuretic monotherapy in most patients, and only initiating combination therapy in those with BP > 160/100 mmHg. Therefore, the aim of the current narrative review is to examine the rationale for using SPCs to treat hypertension in Colombia, in the context of the major issues for BP control there. There is evidence of widespread therapeutic inertia in hypertension management, particularly in primary care, in Colombia. Moreover, combination therapy, angiotensin-converting enzyme inhibitors, and long-acting calcium channel blockers, which are internationally recommended as first-line drug therapies, are underutilized there. Adherence to antihypertensive therapy is low in Colombia and may be enhanced by use of SPCs as well as better patient education and follow-up. While there are promising national initiatives to improve BP management, more needs to be done by individual physicians. Antihypertensive SPCs are available on the national essential medicines list and may help to overcome some of the problems with suboptimal adherence, therapeutic inertia, and low rates of BP control that contribute to the high cardiovascular death rate in Colombia., (© 2024.

Purpose: To share a Latin-American perspective of the use of telemedicine, together with blood pressure measurements outside the medical office, as a potential contribution to improving access to the health system, diagnosis, adherence, and persistence in hypertension treatment., Material and Methods: A document settled by a Writing Group of Mexico Hypertension Experts Group, Interamerican Society of Hypertension, Epidemiology and Cardiovascular Prevention Council of the Interamerican Society of Cardiology, and National Cardiologist Association of Mexico., Results: In almost all Latin American countries, the health sector faces two fundamental challenges: (1) ensure equitable access to quality care services in a growing population that faces an increase in the prevalence of chronic diseases, and (2) optimise the growing costs of health services, maintaining equity, accessibility, universality, and quality. Telehealth proposes an innovative approach to patient management, especially for chronic conditions, intending to provide remote consultation, education, and follow-up to achieve measurements and goals. It is a tool that promises to improve access, empower the patient, and somehow influence their behaviour about lifestyle changes, improving prevention and reducing complications of hypertension. The clinical practitioner has seen increased evidence that the use of out-of-office blood pressure (BP) measurement and telemedicine are helpful tools to keep patients and physicians in contact and promote better pharmacological adherence and BP control. A survey carried out by medical and scientific institutions showed that practitioners are up-to-date with telemedicine, had internet access, and had hardware availability., Conclusions: A transcendent issue is the need to make the population aware of the benefits of taking blood pressure to avoid complications of hypertension, and in this scenario, promote the creation of teleconsultation mechanisms for the follow-up of patients diagnosed with hypertension.

The present document provides scientific evidence reviewed and analysed by a group of specialist clinicians in hypertension that aims to give an insight into a pharmacological strategy to improve blood pressure control. Evidence shows that most hypertensive patients will need at least two drugs to achieve blood pressure goals. There is ample evidence showing that treatment adherence is inversely related to the number of drugs taken. Observational studies show that use of drug combinations to initiate treatment reduces the time to reach the treatment goal and reduces CVD, especially with single pill combinations (SPCs). This work, based on recommendations of the Argentine Federation of Cardiology and Argentine Society of Hypertension as a reference, aims to review the more recent evidence on SPC, and to serve as guidelines for health professionals in their clinical practice and to the wider use of SPCs for the treatment of hypertension. Evidence from clinical trials on the effectiveness and adverse effects of using SPCs are provided. An analysis is also made of the main contributions of SPCs in special populations, e.g., elderly and diabetic patients, and its use in high risk and resistant hypertension. The effects of SPCs on hypertensive-mediated organ damage is also examined. Finally, we provide some aspects to consider when choosing treatments in the economic context of Latin-America for promoting the most efficient use of resources in a scarce environment and to provide quality information to decision makers to formulate safe, cost-effective, and patient-centered health policies. Finally, future perspectives and limitations in clinical practice are also discussed., (© 2021. The Author(s), under exclusive licence to Springer Nature Limited.)

The aim of the study was to evaluate hypertension treatment effects on mechanical efficiency of the cardiovascular system and cardiac reverse remodeling in hypertensive patients. This is an observational prospective study, consecutive hypertension patients. Left ventricle mass index measured by Devereux 2D method and diastolic function following the Guidelines from the American Society of Echocardiography and the European Association of Cardiovascular Imaging. Left ventricular end systolic elastance (Ees) was measured by Guarracino calculator, the effective arterial elastance (Ea) and ventricular-arterial coupling (VAC) measured by Sunagawa et al. single beat method adapted by Chen et al. in human ventricles. The sample was analyzed in quartiles (Q) according to VAC. Follow-up 2 years. In total, 288 patients, mean age 56.3 ± 12.5 years and 168 patients (58.3%) males. VAC increased from 0.303 ± 0.07 to 0.54 ± 0.25 (p < 0.005) in Q1 mainly due to a reduction in Ees from 5.25 ± 2.3 to 3.68 ± 0.25 mmHg/ml (p < 0.01), while Ea increased from 1.5 ± 0.53 to 1.64 ± 0.56 mmHg/ml (p = NS). The frequency of LVH was reduced from 31.9 to 10.8% in Q1 (p < 0.025). The frequency of normal diastolic function increased from 75 to 94.6% (p < 0.01) in Q1, from 78.7 to 100% in Q2 (p < 0.005), from 87.1 to 100% (p < 0.025) in Q3 and from 88.7 to 100% (0,025) in Q4. Patients with the worst ventricular-arterial uncoupling were the most benefited from hypertension treatment. Regression of left ventricular hypertrophy was observed only in the group of patients with the worst ventricular-arterial uncoupling, while improvement in diastolic function was demonstrated in all quartiles of patients., (© 2022.

The aim of this study was to explore the different attitudes of physicians regarding international recommendations for the management of dyslipidemia in routine medical practice. Seven clusters of questions were designed to characterize the surveyed population. Eight hundred ninety-eight physicians answered the survey, 68.3% cardiologists and 40.0% had specialties related to cardiovascular prevention. 29.6% of physicians supported LDL goals above 70 mg/dL in secondary prevention. Acceptance of values lower than 70 mg/dL was associated with greater levels of continuing education (OR 0.64, 95% CI 0.45-0.91; P = 0.014), specialization in preventive cardiology (OR 0.49, 95% CI 0.28-0.88; P = 0.017) or diabetology (OR 0.48, 95% CI 0.24-0.98; P = 0.043). A less aggressive attitude toward the achievement of guideline goals were observed in physicians who considered LDL values higher than 70 mg/dL as the goal in secondary prevention. One-third of physicians in the survey do not follow goals recommended by international guidelines., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Purpose: To assess the opinion of Latin-American physicians on remote blood pressure monitoring and telehealth for hypertension management., Material and Methods: Cross-sectional survey of physicians residing in Latin-America. The study was conducted by the Mexico Hypertension Experts Group, Interamerican Society of Hypertension, Interamerican Society of Cardiology Epidemiology and Cardiovascular Prevention Council, and National Cardiologist Association of Mexico. An online survey composed of 40 questions using Google Forms was distributed from 7 December 2021, to 3 February 2022. The survey was approved by the GREHTA Ethics Committee and participation was voluntary and anonymous. Multiple logistic regression models were constructed to identify the challenges of telehealth., Results: 1753 physicians' responses were gathered. The responses came from physicians from different Latin-American countries, as follows: 24% from Mexico, 20.6% from Argentina, 14.7% from Colombia, 10.9% from Brazil, 8.7% from Venezuela, 8.2% from Guatemala and 3.2% from Paraguay. Responders with a high interest in carrying out their assistance task through remote telemonitoring reached 48.9% (821), while 43.6% are already currently conducting telemonitoring. A high number, 62%, claimed to need telemonitoring training. There is a direct relation between higher interest in telemonitoring and age, medical specialty, team working, residence in the biggest cities, expectations regarding telemedicine and reimbursement., Conclusions: Remote monitoring is feasible in Latin-America. General practitioners and specialists from bigger cities seem eager and are self-perceived as well-trained and experienced. Facilities and resources do not seem to be a challenge but training reinforcement and telemedicine promotion is necessary for those physicians less motivated.PLAIN LANGUAGE SUMMARYWhat is the context?Hypertension is one of the leading worldwide modifiable risk factors for premature death. Strong evidence supports that effective treatment of this condition results in a significant reduction of hard outcomes.Only 20%-30% of hypertensive patients are within the blood pressure targets recommended by guidelines in Latin-America. There is an urgent need to implement innovative strategies to reverse this alarming health situation.What is new?Latin-American physicians were highly predisposed to telemonitoring practice. This high motivation was not influenced by hardware or software availability, technological knowledge or experience, by volume of monthly consultations, or by area (private-public) where the care activity is carried out.This high motivation may be supported by the conviction that this practice could be very useful as a complement to face-to-face assistance and a highly effective tool to improve adherence even though respondents considered that just 10% of the patients would prefer telemonitoring over office consultation.What is the impact?Facilities and resources do not seem to be a challenge but training reinforcement and telemedicine promotion is necessary for those physicians less motivated. The general perception is that it is necessary to move forward to resolve legal gaps and financial aspects.Physicians must adapt to changes and develop new communication strategies in a world where the unrestricted access to teleinformation makes patients self-perceived as experts.

Adequate diagnosis, treatment, and control of arterial hypertension (AHT) continues to be a pending issue in the attempt to reduce the incidence of premature mortality and disability due to cardiovascular disease, which is a reality worldwide and in the region of the Americas in particular.Despite having adequate diagnostic algorithms and efficient treatment schemes, the gap between medical knowledge and reality reveals the great difficulty in ensuring that patients follow recommendations. Adherence to treatment is a great challenge and a proper understanding of its dimensions is essential when designing strategies to improve control of AHT.It is clear that part of the solution is having adequate information and disseminating it, but actions that guarantee implementation are no less important. That is why clinical practice guidelines that try to address this problem are welcome. The recent publication of the World Health Organization's guidance on arterial hypertension is a clear example of this type of initiative.Implementation programs are arguably one of the biggest challenges in contemporary medicine. The development of multimodal interventions aimed at improving response capacity at the first level of care and promoting the development of integrated health services networks appears to be the most appropriate way to achieve adequate control of AHT.Scientific societies clearly play an important role in these initiatives by providing support and coordinating interactions among the different actors involved.

Introduction: The increase in the pulsatile component of left ventricle afterload is suspected to cause a mismatch between the left ventricle (LV) and the vascular tree., Aim: To demonstrate that ventricular-arterial uncoupling is frequently present in the development of LV hypertrophy (H) and diastolic dysfunction (DD) in hypertension (HBP)., Methods: Observational study, HBP patients with ejection fraction > 54%. Conventional 2D echocardiography and tissue Doppler performed following imaging guidelines. LV end systolic elastance (Ees), the effective arterial elastance (Ea), and ventricular-arterial coupling (VAC) measured by Chen single beat method., Results: 288 patients, mean age 56.3 ± 12.5 years and 168 patients (58.3%) males. Mean LV mass index was 87.2 ± 20.4 grs/m 2 and frequency of LVH 20.1% (58 patients). The mean VAC was 0.54 ± 9.23. LV Stroke volume, stroke work and systolic stress were 46.2 ± 10.3 cc/m 2 , 91.4 ± 22.2 g-min/m 2 , and 57 ± 14.6 dynes/cm 2 in quartile 1, and 33.5 ± 6.6 cc/m 2 , 65.5 ± 15.2 g-min/m 2 , and 77.8 ± 17.1 dynes/cm 2 , in quartile 4, respectively (p < 0.001). Peripheral resistance index was 3349 ± 1072 and 4410 ± 1143 dynes*s/cm-5/m 2 quartiles 1 vs. 4 (p < 0.005). The frequency of LVH was 31.9% in quartile 1 and 11.3% in quartile 4 (p < 0.005) and LVH or DD was 37.5% and 12.7%, respectively (p < 0.001)., Conclusions: Stroke volume and stroke work were significantly increased while systolic stress and peripheral resistance index were significantly reduced in patients with worst VAC. Ventricular-arterial uncoupling is mostly caused by an increase in Ees rather than by an elevation of Ea. LVH or DD are more frequent in the worst cases of ventricular-arterial uncoupling., (© 2022.
