In many low- and middle-income countries, there is a wide gap between evidencebased recommendations and current practice. Treatment of major CVD risk factors remains suboptimal, and only a minority of patients who are treated reach their target levels for blood pressure, blood sugar and blood choles...terol.
In other areas, overtreatment can occur with the use of non-evidence-based
protocols. The aim of using standard treatment protocols is to improve the quality
of clinical care, reduce clinical variability and simplify the treatment options,
particularly in primary health care. Standard treatment protocols can be developed by preparing new national treatment guidelines or by adapting or adopting international guidelines.
The Evidence-based protocols module uses hypertension and diabetes screening
and treatment as an entry point to control cardiovascular risk factors, prevent target organ damage, and reduce premature morbidity and mortality. A comprehensive risk- based approach for integrated management of hypertension, diabetes, and high cholesterol is included in the Risk-based CVD management module.
This module includes clinical practice points and sample protocols for:
1. hypertension detection and treatment
2. type 2 diabetes detection and treatment
3. identifying basic emergencies – care and referral.
HEARTS emphasizes adaptation, dissemination, and use of a standardized set of
simple clinical-management protocols, which should be drug- and dose-specific,
and include a core set of medications. The simpler the protocols and management tools, the more likely they are to be used correctly, and the higher the likelihood that a programme will achieve its goals.

Cardiovascular disease (CVD) is the leading cause of global deaths, with the majority occurring in low- and middle-income countries (LMIC). The primary and secondary prevention of CVD is suboptimal throughout the world, but the evidence-practice gaps are much more pronounced in LMIC. Barriers at the... patient, health-care provider, and health system level prevent the implementation of optimal primary and secondary prevention. Identification of the particular barriers that exist in resource-constrained settings is necessary to inform effective strategies to reduce the identified evidence-practice gaps. Furthermore, targeting modifiable factors that contribute most significantly to the global burden of CVD, including tobacco use, hypertension, and secondary prevention for CVD will lead to the biggest gains in mortality reduction. We review a select number of novel, resource-efficient strategies to reduce premature mortality from CVD, including: (1) effective measures for tobacco control; (2) implementation of simplified screening and management algorithms for those with or at risk of CVD, (3) increasing the availability and affordability of simplified and cost-effective treatment regimens including combination CVD preventive drug therapy, and (4) simplified delivery of health care through task-sharing (non-physician health workers) and optimizing self-management (treatment supporters). Developing and deploying systems of care that address barriers related to the above, will lead to substantial reductions in CVD and related mortality.

Cardiovascular diseases, principally ischemic heart disease (IHD), are the most important cause of death and disability in the majority of low- and lower-middle-income countries (LLMICs). In these countries, IHD mortality rates are significantly greater in individuals of a low socioeconomic status (...SES).
Three important focus areas for decreasing IHD mortality among those of low SES in LLMICs are (1) acute coronary care; (2) cardiac rehabilitation and secondary prevention; and (3) primary prevention. Greater mortality in low SES patients with acute coronary syndrome is due to lack of awareness of symptoms in patients and primary care physicians, delay in reaching healthcare facilities, non-availability of thrombolysis and coronary revascularization, and the non-affordability of expensive medicines (statins, dual anti-platelets, renin-angiotensin system blockers). Facilities for rapid diagnosis and accessible and affordable long-term care at secondary and tertiary care hospitals for IHD care are needed. A strong focus on the social determinants of health (low education, poverty, working and living conditions), greater healthcare financing, and efficient primary care is required. The quality of primary prevention needs to be improved with initiatives to eliminate tobacco and trans-fats and to reduce the consumption of alcohol, refined carbohydrates, and salt along with the promotion of healthy foods and physical activity. Efficient primary care with a focus on management of blood pressure, lipids and diabetes is needed. Task sharing with community health workers, electronic decision support systems, and use of fixed-dose combinations of blood pressure-lowering drugs and statins can substantially reduce risk factors and potentially lead to large reductions in IHD. Finally, training of physicians, nurses, and health workers in IHD prevention should be strengthened.

Background: Cardiovascular disease (CVD), mainly heart attack and stroke, is the
leading cause of premature mortality in low and middle income countries (LMICs).
Identifying and managing individuals at high risk of CVD is an important strategy to prevent and control CVD, in addition to multisector...al population-based interventions to reduce CVD risk factors in the entire population.
Methods: We describe key public health considerations in identifying and managing individuals at high risk of CVD in LMICs.
Results: A main objective of any strategy to identify individuals at high CVD risk is to maximize the number of CVD events averted while minimizing the numbers of
individuals needing treatment. Scores estimating the total risk of CVD (e.g. ten-year risk of fatal and non-fatal CVD) are available for LMICs, and are based on the main CVD risk factors (history of CVD, age, sex, tobacco use, blood pressure, blood cholesterol and diabetes status). Opportunistic screening of CVD risk factors enables identification of persons with high CVD risk, but this strategy can be widely applied in low resource settings only if cost effective interventions are used (e.g. the WHO Package of Essential NCD interventions for primary health care in low resource settings package) and if treatment (generally for years) can be sustained, including continued availability ofaffordable medications and funding mechanisms that allow people to purchase medications without impoverishing them (e.g. universal access to health care). Thisalso emphasises the need to re-orient health systems in LMICs towards chronic diseases management.
Conclusion: The large burden of CVD in LMICs and the fact that persons with high
CVD can be identified and managed along cost-effective interventions mean that
health systems need to be structured in a way that encourages patient registration, opportunistic screening of CVD risk factors, efficient procedures for the management of chronic conditions (e.g. task sharing) and provision of affordable treatment for those with high CVD risk. The focus needs to be in primary care because that is where most of the population can access health care and because CVD programmes can be run effectively at this level.

The Coronavirus Disease 2019 (COVID-19) has had a continuous and robust impact on world health. The resulting COVID-19 pandemic has had a devastating physical, mental and fiscal impact on the millions of people living with noncommunicable diseases (NCDs), as they have a higher risk of severe illness... and death from COVID-19. COVID-19 has been associated with an
excess in all-cause and cardiovascular disease (CVD) mortality beyond that related to the infection itself and its immediate consequences. Studies in the
United Kingdom (UK) and United States of America (USA) have clearly shown increasing deaths from ischemic heart disease, stroke and hypertensive disease due to COVID-19. Overall, the impact has been greater in individuals with lower socioeconomic status, even in high income nations.

The World Heart Federation (WHF) commenced a Roadmap initiative in 2015 to reduce the global burden of cardiovascular disease and resultant burgeoning of healthcare costs. Roadmaps provide a blueprint for implementation of priority solutions for the principal cardiovascular diseases leading to death... and disability. Atrial fibrillation (AF) is one of these conditions and is an increasing problem due to ageing of the world’s population and an increase in cardiovascular risk factors that predispose to AF. The goal of the AF roadmap was to provide guidance on priority interventions that are feasible in multiple countries, and to identify roadblocks and potential strategies to overcome them.

Non-communicable diseases (NCDs) are the second common cause of death in sub-Saharan Africa (SSA) accounting for about 35% of all deaths, after a composite of communicable, maternal, neonatal, and nutritional diseases. Despite prior perception of low NCDs mortality rates, current evidence suggests t...hat SSA is now at the dawn of the epidemiological transition with contemporary double burden of disease from NCDs and communicable diseases. In SSA, cardiovascular diseases (CVDs) are the most frequent causes of NCDs deaths, responsible for approximately 13% of all deaths and 37% of all NCDs deaths. Although ischemic heart disease (IHD) has been identified as the leading cause of CVDs mortality in SSA followed by stroke and hypertensive heart disease from statistical models, real field data suggest IHD rates are still relatively low. The neglected endemic CVDs of SSA such as endomyocardial fibrosis and rheumatic heart disease as well as congenital heart diseases remain unconquered. While the underlying aetiology of heart failure among adults in high-income countries (HIC) is IHD, in SSA the leading causes are hypertensive heart disease, cardiomyopathy, rheumatic heart disease, and congenital heart diseases. Of concern is the tendency of CVDs to occur at younger ages in SSA populations, approximately two decades earlier compared to HIC. Obstacles hampering primary and secondary prevention of CVDs in SSA include insufficient health care systems and infrastructure, scarcity of cardiac professionals, skewed budget allocation and disproportionate prioritization away from NCDs, high cost of cardiac treatments and interventions coupled with rarity of health insurance systems. This review gives an overview of the descriptive epidemiology of CVDs in SSA, while contrasting with the HIC and highlighting impediments to their management and making recommendations.

Objective: To identify gaps in national stroke guidelines that could be bridged to enhance the quality of stroke care services in low- and
middle-income countries.
Methods: We systematically searched medical databases and websites of medical societies and contacted international organizations.
Co...untry-specific guidelines on care and control of stroke in any language published from 2010 to 2020 were eligible for inclusion. We reviewed
each included guideline for coverage of four key components of stroke services (surveillance, prevention, acute care and rehabilitation).
We also assessed compliance with the eight Institute of Medicine standards for clinical practice guidelines, the ease of implementation of
guidelines and plans for dissemination to target audiences.
Findings: We reviewed 108 eligible guidelines from 47 countries, including four low-income, 24 middle-income and 19 high-income countries.
Globally, fewer of the guidelines covered primary stroke prevention compared with other components of care, with none recommending
surveillance. Guidelines on stroke in low- and middle-income countries fell short of the required standards for guideline development;
breadth of target audience; coverage of the four components of stroke services; and adaptation to socioeconomic context. Fewer low- and
middle-income country guidelines demonstrated transparency than those from high-income countries. Less than a quarter of guidelines
encompassed detailed implementation plans and socioeconomic considerations.
Conclusion: Guidelines on stroke in low- and middle-income countries need to be developed in conjunction with a wider category of
health-care providers and stakeholders, with a full spectrum of translatable, context-appropriate interventions.

Cardiovascular diseases (CVDs) are a growing public health problem in Ghana and other African countries. Strokes and other CVDs have become a leading cause of death due to increasing risk factors such as hypertension. According to the Global Burden of Disease study (GBD), ischaemic heart disease was... the fourth leading cause of death in Ghana in 2016. The prevalence of hyper-
tension, a major risk factor for CVDs, is increasing rapidly and ranges from 19% to 48%, according to the Ghana Health Service Annual Report, 2017, due to rising life expectancy and the increasing prevalence of contributing factors such as overweight/obesity. Early diagnosis and adequate management of the risk factors can reduce the fatal consequences of CVDs.
At the heart of improving risk assessment and management of CVDs are nationally approved guidelines, which facilitate standardisation of care approaches.
These guidelines developed by experts from all levels of health care and stakeholders capture all recommended approaches and necessary information for clinicians and other healthcare workers on CVDs. They also serve as a practical guide for assessing and managing the most important CVDs prevalent in Ghana and can be used at all levels of care namely health facilities without a doctor; with a general practitioner and with a physician specialist.

Air pollution is a major environmental risk factor and contributor to chronic, noncommunicable diseases (NCDs). However, most public health approaches to NCD prevention focus on behavioural and biomedical risk factors, rather than environmental risk factors such as air pollution. This article discus...ses the implications of such a focus. It then outlines the opportunities for those in public health and environmental science to work together across three key areas to address air pollution, NCDs and climate change: (a) acknowledging the shared drivers, including corporate determinants; (b) taking a ‘co-benefits’ approach to NCD prevention; and (c) expanding prevention research and evaluation methods through investing in systems thinking and intersectoral, cross-disciplinary collaborations.

The aim of the present paper is to review capacity building in public health nutrition (PHN), the need for which has been stressed for many years by a range of academics, national and international organisations. Although great strides have been made worldwide in the science of nutrition, there rema...in many problems of undernutrition and increasingly of obesity and related chronic diseases. The main emphasis in capacity building has been on the nutrition and health workforce, but the causes of these health problems are multifactorial and require collaboration across sectors in their solution. This means that PHN capacity building has to go beyond basic nutrition and beyond the immediate health workforce to policy makers in other sectors. The present paper provides examples of capacity building activities by various organisations, including universities, industry and international agencies. Examples of web-based courses are given including an introduction to the e-Nutrition Academy. The scope is international but with a special focus on Africa. In conclusion, there remains a great need for capacity building in PHN but the advent of the internet has revolutionised the possibilities.

Asthma is the most common non-communicable disease in children and remains one of the most common throughout the life course. The great majority of the burden of this disease is seen in low-income and middle-income countries (LMICs), which have disproportionately high asthma-related mortality relati...ve to asthma prevalence. This is particularly true for many countries in sub-Saharan Africa. Although inhaled asthma treatments (particularly those containing inhaled corticosteroids) markedly reduce asthma morbidity and mortality, a substantial proportion of the children, adolescents, and adults with asthma in LMICs do not get to benefit from these, due to poor availability and affordability. In this review, we consider the reality faced by clinicians managing asthma in the primary and secondary care in sub-Saharan Africa and suggest how we might go about making diagnosis and treatment decisions in a range of resource-constrained scenarios. We also provide recommendations for research and policy, to help bridge the gap between current practice in sub-Saharan Africa and Global Initiative for Asthma (GINA) recommended diagnostic processes and treatment for children, adolescents, and adults with asthma.

Asthma is the most common chronic condition in children worldwide. It affects daytime activities, sleep and school attendance and causes anxiety to parents, families and other carers. The quality of asthma diagnosis and management globally still needs substantial improvement. From infancy to the tee...nage years, there are age-specific challenges, including both underdiagnosis and overdiagnosis with stigma-related barriers to treatment in some cultures and in adolescents. The Paediatric Asthma Project Plan has been initiated to strengthen diagnosis and management of asthma. This encompasses a vision for the next 10–15 years, building on the knowledge and experience from previous educational projects. It will take into account the educational needs of patients, carers and healthcare professionals as well as the accessibility and affordability of medication, particularly in low and middle-income countries where the prevalence of asthma is rising more rapidly. This overview presents a first step for those involved in the diagnosis and management of childhood asthma to strengthen care for children globally.
