“…Further they argued the need of understanding and identification of risk factors other than conventional risk factors and timely risk stratification in these patients. Similarly, Ashraf T et al 19 also highlighted need of a population-specific risk stratification system for primary prevention in this population.…”

Objectives: To determine the pattern of coronary artery diseases (CAD) in patients under 40 years of age with acute coronary syndrome (ACS) presenting at Hyderabad Satellite Center of National Institute of Cardiovascular Disease (NICVD), Pakistan. Methodology: This cross-sectional study was conducted at cardiology department of the NICVD, Hyderabad Satellite Center. Both male and female patients, between 18 to 40 years of age, diagnosed with acute coronary syndrome (ACS), and undergone coronary angiography were included in this study. Angiographic patterns in terms of extent of the disease (number of diseased vessels and localization of lesion) were assessed. Results: Total of 220 young patients included. Patients were predominantly male (91.8%) with the mean age of 35.3 ± 5 years. Smoking was observed 30.5% followed by hypertension (24.5%) and positive family history of CAD (19.1%). A majority of the patients (79.1%) were diagnosed as with ST-elevation myocardial infarction (STEMI) with anterior wall myocardial infarction (MI) as the most common (57.3%) type of MI. Most of the patients (70%) had single vessel diseases (SVD) with left anterior descending artery (LAD) as the most commonly diseases vessel (53.6%). Nine (4.1%) patients had significant left main disease and 6.4% had non-obstructive CAD. Conclusion: The common clinical presentation of ACS in younger patients is STEMI. Smoking is the commonest risk factor followed by hypertension and family history of CAD. More than 2/3rd of the young patients are expected to have single vessel diseases with LAD as the most commonly diseased vessel.

About one fourth of the world population, living in the South Asia region are at an increased risk of atherosclerotic cardiovascular diseases (ASCVD).1,2 Pakistan’s population comprises of over 200 million inhabitants of the South Asian origin. According to a recent study, more than 30% of the Pakistani individuals were at high risk (>7.5%) of 10 years of ASCVD event. Smoking, diabetes (type II), systemic hypertension, and high cholesterol were the most prevalent modifiable risk factors.3 Ten years risk assessment of ASCVD was done in Karachi (a city representing the whole of Pakistan because of multi ethnic composition) by offering pooled cohort equation and Astronaut Cardiovascular Health and Risk Modification (Astro-CHARM) risk calculators.3 Risk stratification in South Asian populations comparable with studies done in the US.1 The study done by Ashraf et al.4 showed an overall hypertension to be 45.6%, diabetes mellitus 15.8%, current smoker 14.25%, family history of myocardial infarction 30.57%. Regarding ethnic distribution to ethnicities of this population Urdu speaking were shown to have an increase trend for diabetes, smoking and family history of heart attack while hypertension in Pushtoons (Table 1). Regarding distribution of coronary artery calcium (CAC) score for various ethnicities, rate of moderate (100 to 399 Agatstan Units) and high (≥ 400 Agatston Units) risk among Punjabis was 4% and 8% respectively, while, for Urdu speaking it was 7% and 2.3% respectively.5 The pairwise comparison of ten years risk of atherosclerotic cardiovascular disease (ASCVD) event by various ethnicities of Pakistan with Pooled Cohort Equation (PCE) and Astro-CHARM showed Urdu speaking at high risk and Sindhi at least risk.5 What needs be done? Implementation of pooled cohort equation and Astro-CHARM in Pakistani population needs to be done through general practitioners. This can be done through pharmaceutical friends by involving all private and public institutions of the countries. This purpose can be achieved through delivering lecturers and demonstrations either by direct lecturers or usual social media i.e. Zoom meetings, webinars, etc. An app can be created for pooled and Astro-CHARM which can be installed in GPs mobile phone. After risk stratification, life style modification, use of statins will be delivered to the general public. All data assimilated will be analyzed and share with medical community for further preventive strategies. A major setback in the risk calculator is that the risk score for subjects under 40 years of age cannot be calculated. Pakistan population having cardiac events are mostly of young age group.6 To overcome this plan is to have a baseline estimation of risk using this calculator in young patients of mentioned age group. This young cohort will be followed through the same mechanism of risk stratification and follow up for 5 years. Although ASCVD scoring system including PCE and Astro-CHARM may help in primary prevention of Pakistan population in identifying individuals at high risk. Through risk calculators need validation with similar cohorts in this population with appropriate changes as needed.References: Volgman AS, Palaniappan LS, Aggarwal NT, Gupta M, Khandelwal A, Krishnan AV, et al.
