RESUMEN
Background: Arterial hypertension is highly prevalent in Mexico; nevertheless, there are limited insights regarding its management during the COVID-19 pandemic. Here, we estimate the prevalence of clinical and treatment profiles of arterial hypertension and explore associated factors for undiagnosed and uncontrolled hypertension using a cross-sectional survey endorsed by the Collaborative Group on Arterial Hypertension from the Mexican Institute of Social Security. Methods: Our survey was conducted from May to November 2021 using the May-Measurement Month 2021 protocols of the International Society of Hypertension. Arterial hypertension (defined as: blood pressure [BP] ≥140/90 mmHg, previous diagnosis, or taking antihypertensives) and its clinical and treatment profiles were classified according to the World Hypertension League Expert Committee. Mixed-effects logistic regression models were used to explore associated factors for undiagnosed and uncontrolled hypertension. Results: Among 77,145 screened participants (women: 62.4%; median age: 46 [IQR: 32-59] years), the prevalence of arterial hypertension was 35.7% (95% CI: 35.3-36.0, n = 27,540). Among participants with arterial hypertension, 30.9% (95% CI: 30.4-31.5, n = 8,533) were undiagnosed, 6.6% (95% CI: 6.3%-6.9%, n = 1,806) were diagnosed but untreated, 43.4% (95% CI: 42.9-44.0, n = 11,965) had uncontrolled hypertension, and only 19% (95% CI: 18.6%-19.5%, n = 5,236) achieved hypertension control (BP < 130/80 mmHg). Explored associated factors for undiagnosed and uncontrolled hypertension include being men, living in the central and southern regions, lower educational attainments, higher use of pharmacological agents, and previous COVID-19 infection. Conclusion: Our findings suggest that adverse arterial hypertension profiles, mainly undiagnosed and uncontrolled hypertension, were highly prevalent during the context of the COVID-19 pandemic in Mexico.

May Measurement Month 2021 (MMM21) in Mexico was an opportunistic survey that aimed to improve blood pressure awareness at the individual and population levels and to analyse the impact of the COVID-19 pandemic on the prevalence, knowledge, and rates of hypertension in the country. This survey followed the methodology of MMM, previously published. The total number of participants screened was 77 547, of which 47 793 (61.6%) were female and 29 178 (37.6%) were male. The mean age (SD) was 46.2 (16.6) years. Of all 77 547 participants, 14 939 (19.3%) had hypertension, of which 48% were aware. The frequency and awareness of hypertension in this survey are similar to those reported before the pandemic (MMM19-Mexico and the 2019 National Health Survey), suggesting that the impact of the COVID-19 pandemic in these parameters of arterial hypertension was not as important as expected. These data are concordant with the official reports in Mexico that showed that the pandemic had a severe impact on cardiovascular mortality but did not modify mortality due to hypertension or stroke.
RESUMEN
BACKGROUND: Arterial hypertension is a significant cause of morbidity and mortality in Mexico. However, there is limited evidence to understand blood pressure management and cardiometabolic profiles. Here, we aim to assess the prevalence of controlled and uncontrolled blood pressure, as well as the prevalence of cardiometabolic risk factors among patients from the Mexican Registry of Arterial Hypertension (RIHTA). METHODS: We conducted a cross-sectional analysis of participants living with arterial hypertension registered on RIHTA between December 2021 and April 2023. We used both the 2017 ACC/AHA and 2018 ESC/ESH thresholds to define controlled and uncontrolled arterial hypertension. We considered eleven cardiometabolic risk factors, which include overweight, obesity, central obesity, insulin resistance, diabetes, hypercholesterolemia, hypertriglyceridemia, low HDL-C, high LDL-C, low-eGFR, and high cardiovascular disease (CVD) risk. RESULTS: In a sample of 5,590 participants (female: 61%, nâ =â 3,393; median age: 64 [IQR: 56-72] years), the prevalence of uncontrolled hypertension varied significantly, depending on the definition (2017 ACC/AHA: 59.9%, 95% CI: 58.6-61.2 and 2018 ESC/ESH: 20.1%, 95% CI: 19.0-21.2). In the sample, 40.43% exhibited at least 5-6 risk factors, and 32.4% had 3-4 risk factors, chiefly abdominal obesity (83.4%, 95% CI: 82.4-84.4), high LDL-C (59.6%, 95% CI: 58.3-60.9), high CVD risk (57.9%, 95% CI: 56.6-59.2), high triglycerides (56.2%, 95% CI: 54.9-57.5), and low HDL-C (42.2%, 95% CI: 40.9-43.5). CONCLUSIONS: There is a high prevalence of uncontrolled hypertension interlinked with a high burden of cardiometabolic comorbidities in Mexican adults living with arterial hypertension, underscoring the urgent need for targeted interventions and better healthcare policies to reduce the burden of the disease in our country.

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.

Arterial hypertension is the main preventable cause of premature mortality worldwide. Across Latin America, hypertension has an estimated prevalence of 25.5-52.5%, although many hypertensive patients remain untreated. Appropriate treatment, started early and continued for the remaining lifespan, significantly reduces the risk of complications and mortality. All international and most regional guidelines emphasize a central role for renin-angiotensin-aldosterone system inhibitors (RAASis) in antihypertensive treatment. The two main RAASi options are angiotensin-converting enzyme inhibitors (ACEis) and angiotensin II receptor blockers (ARBs). Although equivalent in terms of blood pressure reduction, ACEis are preferably recommended by some guidelines to manage other cardiovascular comorbidities, with ARBs considered as an alternative when ACEis are not tolerated. This review summarizes the differences between ACEis and ARBs and their place in the international guidelines. It provides a critical appraisal of the guidelines based on available evidence from randomized controlled trials (RCTs) and meta-analyses, especially considering that hypertensive patients in daily practice often have other comorbidities. The observed differences in cardiovascular and renal outcomes in RCTs may be attributed to the different mechanisms of action of ACEis and ARBs, including increased bradykinin levels, potentiated bradykinin response, and stimulated nitric oxide production with ACEis. It may therefore be appropriate to consider ACEis and ARBs as different antihypertensive drugs classes within the same RAASi group. Although guideline recommendations only differentiate between ACEis and ARBs in patients with cardiovascular comorbidities, clinical evidence suggests that ACEis provide benefits in many hypertensive patients, as well as those with other cardiovascular conditions.

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.
What is the context?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.What is new?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.What is the impact?Needs are always infinite, and resources are finite, so according to the World Health Organisation (WHO), advances in electronic, information, and communication technology point to more significant equity in the provision of services, considering the effectiveness, possibility of refining the rationalisation of health spending, and improving health care for remote populations.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.

BACKGROUND: Raised blood pressure (BP) remains the biggest risk factor contributing to the global burden of disease and mortality, despite the COVID-19 pandemic. May Measurement Month (MMM), an annual global screening campaign aims to highlight the importance of BP measurement by evaluating global awareness, treatment and control rates among adults with hypertension. In 2021, we assessed the global burden of these rates during the COVID-19 pandemic. METHODS: Screening sites were set up in 54 countries between May and November 2021 and screenees were recruited by convenience sampling. Three sitting BPs were measured, and a questionnaire completed including demographic, lifestyle and clinical data. Hypertension was defined as a systolic BP at least 140 mmHg and/or a diastolic BP at least 90âmmHg (using the mean of the second and third readings) or taking antihypertensive medication. Multiple imputation was used to impute the average BP when readings were missing. RESULTS: Of the 642â057 screenees, 225â882 (35.2%) were classified as hypertensive, of whom 56.8% were aware, and 50.3% were on antihypertensive medication. Of those on treatment, 53.9% had controlled BP (<140/90âmmHg). Awareness, treatment and control rates were lower than those reported in MMM campaigns before the COVID-19 pandemic. Minimal changes were apparent among those testing positive for, or being vaccinated against COVID-19. Of those on antihypertensive medication, 94.7% reported no change in their treatment because of the COVID-19 pandemic. CONCLUSION: The high yield of untreated or inadequately treated hypertension in MMM 2021 confirms the need for systematic BP screening where it does not currently exist.

May Measurement Month 2019 (MMM19) in Mexico was an opportunistic survey, aimed to improve blood pressure (BP) awareness at the individual and population levels. This survey followed the methodology of MMM19, previously published. The total number of participants screened was 39 700, 56.7% female, 36.6% were of mixed ethnicity, mean age [standard deviation (SD)] was 46.9 (17.4) years, and mean body mass index was 27.2 (SD: 4.4) kg/m2. Seven per cent of the participants reported having diabetes, 2.4% reported having a myocardial infarction in the past, 1.1% stroke, 2.0% were pregnant at the time of the survey, 3.7% of women had suffered from hypertension in a previous pregnancy, 11.4% declared that they were smokers, and 47.0% drank alcohol at least once a week. After multiple imputations, of all 39 700 participants, 10 140 (25.5%) had hypertension; of all participants with hypertension, 43.8% were aware of their diagnosis, 41.7% were on antihypertensive medication, and 27.8% had controlled BP (systolic BP <140 mmHg and diastolic BP <90 mmHg). Of those on antihypertensive medication, 27.8% had controlled BP. In Mexico, MMM is the largest hypertension survey ever done, it provides complementary data to the existing information on arterial hypertension in the country and helps to increase the visibility of hypertension: a priority health problem.
RESUMEN
OBJECTIVE: To project the 10-year clinical outcomes associated with single pill combination (SPC) therapies compared with multi-pill regimens for the management of hypertension in five countries (Italy, Russia, China, South Korea and Mexico). METHODS: A microsimulation model was designed to project health outcomes between 2020 and 2030 for populations with hypertension managed according to four different treatment pathways: current treatment practices (CTP), single drug with dosage titration then sequential addition of other agents (start low and go slow, SLGS), free choice combination with multiple pills (FCC) and combination therapy in the form of a single pill (SPC). Model inputs were derived from the Global Burden of Disease 2017 dataset. Simulated outcomes of mortality, chronic kidney disease (CKD), stroke, ischemic heart disease (IHD), and disability-adjusted life years (DALYs) were estimated for 1,000,000 patients on each treatment pathway. RESULTS: SPC therapy was projected to improve clinical outcomes over SLGS, FCC and CTP in all countries. SPC reduced mortality by 5.4% in Italy, 4.9% in Russia, 4.5% in China, 2.3% in South Korea and 3.6% in Mexico versus CTP and showed greater reductions in mortality than SLGS and FCC. The projected incidence of clinical events was reduced by 11.5% in Italy, 9.2% in Russia, 8.4% in China, 4.9% in South Korea and 6.7% in Mexico for SPC versus CTP. CONCLUSIONS: Ten-year projections indicated that combination therapies (FCC and SPC) are likely to reduce the burden of hypertension compared with conventional management approaches, with SPC showing the greatest overall benefits due to improved adherence.
RESUMEN
In 2015, arterial hypertension was responsible for 18.1% of the total deaths in Mexico and its mortality rate has increased to 29.9% in the last 6 years. It is currently the main risk factor for preventable premature deaths of adults in the country. Good quality epidemiological information is the first step to improve health services. May Measurement Month 2018 (MMM18) in Mexico is an opportunistic survey, which follows the previously published methodology. MMM18 included screening 10 139 participants, 2187 (21.6%) of whom were classified as having hypertension. Of these, 42.0% were aware of the condition before measurement, and 38.0% were on medication, of which 66.5% were controlled. Hence, of all hypertensive patients, 25.3% were controlled (<140/90 mmHg). MMM18 in Mexico provides complementary data to the existing information on arterial hypertension in the country and helps to increase the visibility of hypertension: a priority health problem.
RESUMEN
: The prevalence of hypertension, type 2 diabetes mellitus (DM2) and the metabolic syndrome continues to increase in Latin America, while the rates of diagnosis, treatment and control of these disorders remain low. The frequency of the risk factors that constitute the metabolic syndrome and are associated with an increased risk of cardiovascular disease has not diminished since the publication of the previous consensus. This document discusses the socioeconomic, demographic, environmental and cultural characteristics of most associated Latin American countries and partially explains the lack of better results in improving clinical and public health actions that allow high morbidity and mortality rates caused by cardiovascular diseases and DM2 to be reduced through programs aligned with the so-called precision medicine, which should be predictive, preventive, personalized and participatory. The Consensus ratifies the diagnostic criteria expressed in the previous consensus to define hypertension and DM2 but, for the metabolic syndrome, and in the absence of evidence, the recommendation is to implement a cohort study that determines the abdominal perimeter value associated with hard outcomes, such as DM2 and CVD. Meanwhile, we recommend modifying the criterion to more than 94âcm in men and more than 84âcm in women according to WHO recommendations. We also recommend the carrying out of a study that identifies the situation of hypertension and DM2 in people of African ancestry who, in Latin America, exceed 75 million and whose epidemiology does not include solid studies. With respect to the proposed therapeutic targets, we recommended maintaining those defined in the previous consensus, but insisting that early pharmacological management of prediabetes with metformin should be introduced, as should the treatment of diabetic hypertensive patients with a combination therapy of two fixed-dose antihypertensive drugs and management with statins. To increase adherence, the use of different drugs combined in a single pill (polypill) is recommended. The simplification of the therapeutic regimen is accompanied by greater control of cardiovascular risk factors, both in primary and secondary prevention, and has been shown to be cost-effective. The consensus recommends the use of the currently available polypill combining an angiotensin-converting enzyme inhibitor, a statin and aspirin for secondary cardiovascular prevention and in patients with a high cardiovascular risk, such as hypertension patients with DM2.

Hypertension is a leading risk factor for disease burden globally. An unresolved question is whether grade 1 hypertension (140-159/90-99mmHg) with low (cardiovascular mortality <1% at 10 years) to moderate (cardiovascular mortality ≥1% and <5% at 10 years) absolute total cardiovascular risk (CVR) should be treated with antihypertensive agents. A virtual international consultation process was undertaken to summarize the opinions of select experts. After holistic analysis of all epidemiological, clinical, psychosocial, and public health elements, this consultation process reached the following consensus in hypertensive adults aged <80 years: (1) The question of whether drug treatment in grade 1 should be preceded by a period of some weeks or months during which only lifestyle measures are recommended cannot be evidence based, but the consensus opinion is to have a period of lifestyle alone reserved only to patients with grade 1 "isolated" hypertension (grade 1 uncomplicated hypertension with low absolute total CVR, and without other major CVR factors and risk modifiers). (2) The initiation of antihypertensive drug therapy in grade 1 hypertension with moderate absolute total CVR should not be delayed. (3) Men ≥55 years and women ≥60 years with uncomplicated grade 1 hypertension should automatically be classified within the moderate absolute total CVR category, even in the absence of other major CVR factors and risk modifiers. (4) Statins should be considered along with blood-pressure lowering therapy, irrespective of cholesterol levels, in patients with grade 1 hypertensive with moderate CVR.

Atrial fibrillation (AF) is associated with an increased risk of stroke. AF-related strokes cause greater disability and mortality than those in patients without AF, and are associated with a significant clinical and economic burden in Mexico. Antithrombotic therapy reduces stroke risk in patients with AF and is recommended for all patients except those classified as having a low stroke risk. However, its use is suboptimal all around the world; one study showed that only 4 % of Mexican patients with AF who presented with ischemic stroke were in the therapeutic range for anticoagulation. Vitamin K antagonists (VKAs) such as warfarin or acenocoumarin have long been the only oral anticoagulants for stroke prevention in AF. Although effective, VKAs have disadvantages, including the need for regular coagulation monitoring and dose adjustment. Interactions with numerous common medications and foods contribute to the risk of serious bleeding and thrombotic events in VKA-treated patients. Thus novel oral anticoagulants (NOACs), more properly called direct oral anticoagulants (DOACs), such as dabigatran etexilate, rivaroxaban, apixaban, and edoxaban (not available in Mexico), have been developed. These offer the convenience of fixed-dose treatment without the need for monitoring, and have few drug or food interactions. Pivotal phase III trials have demonstrated that these agents are at least as effective as warfarin in preventing stroke and are associated with a reduced risk of intracranial hemorrhage. With apixaban approved in Mexico in April 2013, clinicians now have the choice of three novel DOACs as alternatives to warfarin. However, it is yet to be established which of these agents should be the first choice, and treatment decisions are likely to depend on the individual patient's characteristics.

BACKGROUND AND AIMS: even though overweight and obesity (O/O) are stated diseases, there is still a claim for a so-called "healthy obese" phenotype. Only few reports have explored the presence of different metabolic phenotypes along the body mass index (BMI) range and their corresponding associations to cardiovascular risks. METHODS: as of BMI, and according to the presence of metabolic syndrome (MS) features (waist circumference, blood pressure, fasting glycemia, and lipid profile), phenotypes were determined. Cardiovascular risk was estimated with atherogenic quotients: total cholesterol/ HDL-c, LDL-c/HDL-c and the triglycerides (TG)/HDL-c index. RESULTS: in 8 405 mexican adults, 36% lean, 43% overweighed and 21% obese, nine phenotypes were identified: for each weight category there were subjects with normal metabolism (none MS factors), intermediate (≤ 2) and dysmetabolic (≥ 3). Only 10.8% of O/O had normal metabolism, and 5.8% of the lean persons were dysmetabolic. Atherogenic risk was higher in dysmetabolic obese persons, but the risk was high among all dysmetabolic people, independently of the weight status. TG/HDL-c showed the same trend. CONCLUSIONS: elevated cardiometabolic risk derives from the high prevalence of O/O. A great proportion of non-obese people have intermediate dysmetabolism. A genetic predisposition to obesity, insulin resistance, diabetes and dyslipidemia in Mexican population is blended to an unhealthy lifestyle, yielding to a catastrophic epidemic of diabetes, and cardiovascular diseases.
Antecedentes y metas: aun cuando el sobrepeso y la obesidad (S/O) son enfermedades reconocidas, hay un reclamo por la existencia de un fenotipo llamado "obeso sano". Pocos estudios han explorado la presencia de diferentes fenotipos metabólicos en los rangos del índice de masa corporal (IMC) y su asociación con riesgo cardiovascular. Métodos: se determinaron fenotipos de acuerdo al IMC y a la presencia de marcadores del síndrome metabólico (SM) (circunferencia abdominal, presión sanguínea, glucemia en ayunas y perfil de lípidos). El riesgo cardiovascular fue estimado con los índices aterogénicos: colesterol total/HDL-c, LDL-c/HDL-c y triglicéridos(TG)/HDL-c. Resultados: en 8.405 adultos mexicanos, 36% delgados, 43% con sobrepeso y 21% obesos, se identificaron 9 fenotipos. Por cada categoría de peso se encontraron sujetos con metabolismo normal (ningún factor de SM), intermedios (≤ 2) y dismetabólicos (≥ 3). Solo el 10.8% de los sujetos con S/O tuvieron metabolismo normal y el 5.8% de los sujetos delgados fueron dismetabólicos. El riesgo aterogénico fue mayor en los sujetos obesos dismetabólicos. El riesgo fue alto entre todos los sujetos dismetabólicos independientemente del peso. El índice TG/ HDL-c mostró las mismas tendencias. Conclusiones: el riesgo cardiometabólico incrementado deriva de la alta prevalencia de S/O. Una gran proporción de sujetos no obesos tiene dismetabolismo intermedio. Una predisposición genética a la obesidad, la resistencia a la insulina, la diabetes y la dislipidémia en la población mexicana, junto con un estilo de vida no saludable da como consecuencia una epidemia catastrófica de diabetes y enfermedades cardiovasculares.

Recent research has focused on the development of evidence-based guidelines that are intended to regulate the conduct of physicians in the diagnosis and control of hypertension, with the goal of achieving greater effectiveness and equity at the lowest possible cost. In Latin America, guidelines are available for the management of hypertension at three levels: national, regional and international. The national and regional Latin American and Caribbean (LAC) guidelines are in fact adaptations of the international guidelines. The potential benefit of applying guidelines developed in other regions to local healthcare decision making is that it will enable decision makers to take advantage of existing analyses and transfer or adapt them to their local contexts. However, this adaptation precludes the assessment of their generalizability and potential transferability. In addition, this region is characterized by wide socioeconomic differences between its inhabitants, both among and within nations. Therefore, new guidelines for the LAC region must include recommendations that are common to all hypertensive patients in the region. Moreover, we advocate the inclusion of a specific section that makes comprehensive recommendations and provides strategies for implementation according to the socioeconomic conditions of particular groups. In addition to developing guidelines that are truly applicable to the LAC region, it seems sensible to consider information that is specific to this region. Furthermore, developing evidence-based guidelines is not enough to affect positively the burden of disease caused by hypertension. Therefore, professional programs are required for the implementation of such guidelines as well as the auditing of their results. Achieving these ambitious goals will require collaborative efforts by many groups including policymakers, international organizations, healthcare providers, universities and society.
