With the growing prevalence of type 2 diabetes, particularly in emerging countries, its management in the context of available resources should be considered. International guidelines, while comprehensive and scientifically valid, may not be appropriate for regions such as Asia, Latin America or Afr...ica, where epidemiology, patient phenotypes, cultural conditions and socioeconomic status are different from America and Europe. Although glycaemic control and reduction of micro- and macrovascular outcomes remain essential aspects of treatment, access and cost are major limiting factors; therefore, a pragmatic approach is required in restricted-resource settings. Newer agents, such as sodium–glucose cotransporter 2 inhibitors and glucagon-like peptide 1 receptor agonists in particular, are relatively expensive, with limited availability despite potentially being valuable for patients with insulin resistance and cardiovascular complications. This review makes a case for the role of more accessible second-line treatments with long-established efficacy and affordability, such as sulfonylureas, in the management of type 2 diabetes, particularly in developing or restricted-resource countries.

What is already known about this topic?
Roughly 80% of the global disease burden caused by diabetes comes from low-and-middle income countries, and 60% of diabetics are located in Asia; 6 of the top 10 countries with the highest prevalence of diabetes are in Asia.
Type 1 diabetes mellitus (T1DM) is less common than type 2 diabetes mellitus but is increasing in frequency in South Africa. It tends to affect younger individuals, and upon diagnosis, exogenous insulin is essential for survival. In South Africa, the health care system is divided into private and pu...blic health care systems. The private system is well resourced, whereas the public sector, which treats more than 80% of the population, has minimal resources. There are currently no studies in South Africa, and Africa at large, that have evaluated the immediate and long-term costs of managing people living with T1DM in the public sector.

Procurement and supply management activities are fundamental to consistent and reliable access to essential medicines and health products. To reduce the impact of CVD, action needs to be taken to improve prevention, diagnosis, care and management of CVD diseases. Affordable essential medicines and t...echnologies to manage CVD disease must be available where and when they are required. Medicines and technologies need to be managed appropriately to ensure that the correct medicines are selected, procured in the right quantities, distributed to facilities in a timely manner, and handled and stored in a way that maintains their quality. This needs to be backed up by policies that enable sufficient quantities to be procured in order to reduce cost inefficiencies, ensure the reliability and security of the distribution system, and encourage the appropriate use of these health products. In order to avoid stock-outs and the disruption of treatment, all related activities need to be conducted in a timely manner, with performance continually monitored, and prompt action taken in response to problems that may arise. Additionally, medication must be dispensed correctly and used rationally by the healthcare provider and patient alike. The purpose of this guide is to explain the necessary steps.

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.

Many low-resource settings have a shortage of physicians and health workers. (1) In order to provide patient-centred continuous care more effectively, primary care systems can include team-based care strategies in their clinic workflows and protocols. Team-based care uses multidisciplinary teams (wh...ich may involve new staff, or the shifting of tasks among existing staff). Teams can include patients themselves, primary care physicians, and other allied health professionals, such as nurses, pharmacists, counsellors, social workers, nutritionists, community health workers, or others. Teams reduce the burden on physicians by utilizing the skills of trained health workers. Strong evidence shows that team-based care is effective in improving hypertension control among patients in a cost-effective way. (2) Some amount of task shifting/team-based care is already taking place in many settings; this module provides further guidance on how to maximize this approach for greater impact.

Monitoring is a crucial element in any successful programme. It is important to
know if health care facilities – and ultimately countries – are meeting the agreed
goals and objectives for preventing and managing cardiovascular diseases (CVD).
Monitoring is the on-going collection, management ...and use of information to
assess whether an activity or programme is proceeding according to plan and/
or achieving defined targets. Not all outcomes of interest can be monitored. Clear
outcomes must be identified that relate to the most important changes expected to result from the project and to what is realistic and measurable within the timescale of the project. Once these outcomes have been articulated, indicators can be chosen that best measure whether the desired outcomes are being met.
To allow progress to be monitored, this module provides a set of indicators on
CVD management. Agreeing on a set of indicators allows countries to compare
progress in CVD management and treatment across different districts or
subnational jurisdictions, as well as at a facility level, identify where performance
can be improved, and track trends in implementation over time. Monitoring
these indicators also helps identify problems that may be encountered so that
implementation efforts can be redirected.
This module starts from the collection of data at facility level, which is then
“transferred up” the system: facility-level data are aggregated at subnational level
to produce reports that allow tracking of facility and subnational performance over time and allow for comparison among facilities. National-level data are obtained through population-based surveys.
Implementing a monitoring system requires action at many levels. At national and
subnational levels, staff can determine how best to integrate data elements into
existing data collection systems – such as the routine service-delivery data that are collected through facility-level Health Management Information Systems (HMIS).
In the facility setting, personnel must be aware of what data are needed. Sample
data-collection tools are included, recognizing that countries use different datamanagement systems for HMIS, so the CVD monitoring tools will be adapted to work with the HMIS system being used by the country, such that the indicators can be collected with minimal disruption/work to existing systems and tools

The South African (SA) guidelines for cardiac patients for non-cardiac surgery were developed to address the need for cardiac risk assessment and risk stratification for elective non-cardiac surgical patients in SA, and more broadly in Africa.
The guidelines were developed by updating the Canadian ...Cardiovascular Society Guidelines on Perioperative Cardiac Risk Assessment
and Management for Patients Who Undergo Non-cardiac Surgery, with a search of literature from African countries and recent publications. The updated proposed guidelines were then evaluated in a Delphi consensus process by SA anaesthesia and vascular surgical experts.
The recommendations in these guidelines are:
1. We suggest that elective non-cardiac surgical patients who are 45 years and older with either a history of coronary artery disease, congestive cardiac failure, stroke or transient ischaemic attack, or vascular surgical patients 18 years or older with peripheral vascular disease require further preoperative risk stratification as their predicted 30-day major adverse cardiac event (MACE) risk exceeds 5%
(conditional recommendation: moderate-quality evidence).
2. We do not recommend routine non-invasive testing for cardiovascular risk stratification prior to elective non-cardiac surgery in adults (strong recommendation: low-to-moderate-quality evidence).
3. We recommend that elective non-cardiac surgical patients who are 45 years and older with a history of coronary artery disease, or stroke or transient ischaemic attack, or congestive cardiac failure or vascular surgical patients 18 years or older with peripheral vascular disease should have preoperative natriuretic peptide (NP) screening (strong recommendation: high-quality evidence).
4. We recommend daily postoperative troponin measurements for 48 - 72 hours for non-cardiac surgical patients who are 45 years and older with a history of coronary artery disease, or stroke or transient ischaemic attack, or congestive cardiac failure or vascular surgical patients 18 years or older with peripheral vascular disease, i.e. (i) a baseline risk >5% for MACE 30 days after elective surgery (if no preoperative NP screening), or (ii) an elevated B-type natriuretic peptide (BNP)/N-terminal-prohormone B-type natriuretic peptide (NT-proBNP) measurement before elective surgery (defined as BNP >99 pg/mL or a NT-proBNP >300 pg/mL) (conditional recommendation: moderate-quality evidence).
Additional recommendations are given for the management of myocardial injury after non-cardiac surgery (MINS) and medications for comorbidities.

Myocardial infarctions are generally clinically classified into ST elevation MI (STEMI) and non-ST elevation MI (NSTEMI), based on changes in ECG. When blood flow to a part of the heart stops or the heart is injured and fails to receive enough oxygen required for its adequate functioning the conditi...on is termed as STEMI or the ‘heart-attack’ in laymen language. Patients with elevated cardiac troponin levels but negative CK-MB who were formerly diagnosed with unstable angina or minor myocardial injury are now reclassified as non-ST-segment elevation Myocardial Infarction (non-STEMI) even in the absence of diagnostic changes.

The American Heart Association and the American College of Cardiology are excited to provide a series of cardiovascular prevention guidelines for the assessment of cardiovascular risk, lifestyle modifications that reduce risk, management of elevated blood cholesterol, and management of increased bod...y weight in adults.
To support the implementation of these guidelines, the Pooled Cohort Equations CV Risk Calculator and additional Prevention Guideline Tools are available in the tools below as well as the AHA Guidelines On-the-Go Mobile App, found in the Apple Store and Google Play. Others may be developed and available in the near future.
The purpose of the ASCVD Risk Calculator is to estimate a patient’s 10-year ASCVD risk at an initial visit to establish a reference point. ACC/AHA guidelines recommend the use of the PCE as an important starting point, not as the final arbiter, for decision making in primary prevention of ASCVD.

Hypertension is referred to as a “silent killer”. Most people with hypertension are unaware of their condition as in most cases, they experience no warning signs or symptoms hence they are not identified or treated. Hypertention is associated with a number of conditions, disability, and causes o...f death. These include: strokes; myocardial infarction; end-stage renal disease; congestive heart failure; peripheral vascular disease and blindness. According to Stats SA, in 2017, hypertensive disorders resulted in 19 900 deaths with a further 44 357 deaths associated with cerebrovascular diseases and other heart diseases. This means around 30% of all deaths in 2017 were associated with increased blood pressure.

Technical package for cardiovascular disease management in primary health care.
HEARTS provides a set of locally adaptable tools for strengthening the
management of CVD in primary health care.
HEARTS is designed to enhance implementation of WHO PEN by providing:
• operational guidance on further integrating CVD management
• technical guidance on evaluating the impact of... CVD care on patient outcomes.
For countries not using WHO PEN, CVD management can still be integrated into
primary health care. The process of implementing HEARTS will vary, depending
on country context, and may require a significant reorienting and strengthening
of the health system. At some sites, existing CVD management services may be
reoriented toward a risk-based approach, while other sites may adopt a public
health approach, strengthening management of particular risk factors such as
hypertension. Whether or not introducing CVD management into primary care is a
new intervention, successful implementation will require engagement with national and local health planners, managers, service providers, and other stakeholders.

Development of cardiovascular disease (CVD) is influenced by risk factors such as:
tobacco use, an unhealthy diet, physical inactivity, obesity (which can result from
a combination of unhealthy diet, physical inactivity, and other factors), elevated
blood pressure (hypertension), abnormal blood l...ipids (dyslipidaemia) and elevated blood glucose (diabetes mellitus). Continuing exposure to these risk factors leads
to further progression of atherosclerosis, resulting in clinical manifestations of these diseases, including angina pectoris, myocardial infarction, heart failure and stroke. Total CVD risk depends on the individual’s overall risk-factor profile.

Cardiovascular disease (CVD) is the leading cause of death in the Americas and raised blood pressure accounts for over 50% of CVD. In the Americas over a quarter of adult women and four in ten adult men have hypertension and the diagnosis, treatment and control are suboptimal. In 2021, the World Hea...lth Organization (WHO) released an updated guideline for the pharmacological treatment of hypertension in adults. This policy paper highlights the facilitating role of the WHO Global HEARTS initiative and the HEARTS in the Americas initiative to catalyze the implementation of this guideline, provides specific policy advice for implementation, and emphasizes that an overarching strategic approach for hypertension control is needed. The authors urge health advocates and policymakers to prioritize the prevention and control of hypertension to improve the health and wellbeing of their populations and to reduce CVD health disparities within and between populations of the Americas.
