Familial hypercholesterolemia (FH) is a modifiable risk factor for premature coronary heart disease but is poorly diagnosed and treated. We leveraged a large laboratory network in Pakistan to study ...the prevalence, gender and geographic distribution of FH.
Data were curated from the Aga Khan University Hospital clinical laboratories, which comprises of 289 laboratories and collection points spread over 94 districts. Clinically ordered lipid profiles from 1st January 2009 to 30th June 2018 were included and data on 1,542,281 LDL-C values was extracted. We used the Make Early Diagnosis to Prevent Early Death (MEDPED) criteria to classify patients as FH and reported data on patients with low-density liporotein -cholesterol (LDL-C) ≥ 190 mg/dL. FH cases were also examined by their spatial distribution.
After applying exclusions, the final sample included 988,306 unique individuals, of which 24,273 individuals (1:40) had LDL-C values of ≥190 mg/dL. Based on the MEDPED criteria, 2416 individuals (1:409) had FH. FH prevalence was highest in individuals 10–19 years (1:40) and decreased as the patient age increased. Among individuals ≥40 years, the prevalence of FH was higher for females compared with males (1:755 vs 1:1037, p < 0.001). Median LDL-C for the overall population was 112 mg/dL (IQR = 88-136 mg/dL). The highest prevalence after removing outliers was observed in Rajan Pur district (1.23% 0.70–2.10%) in Punjab province, followed by Mardan (1.18% 0.80–1.70%) in Khyber Pakhtunkhwa province, and Okara (0.99% 0.50–1.80%) in Punjab province.
There is high prevalence of actionable LDL-C values in lipid samples across a large network of laboratories in Pakistan. Variable FH prevalence across geographic locations in Pakistan may need to be explored at the population level for intervention and management of contributory factors. Efforts at early diagnosis and treatment of FH are urgently needed.
A 30-year-old woman presented to the emergency room with recurrent seizures for 5 days. She had been diagnosed with epilepsy 2 years previously but stopped treatment due to the side effects of her ...medications. She was now experiencing episodes every 15–30 min. While undergoing a brain MRI to investigate for structural central nervous system pathology, she experienced another episode, preceded by prodromal symptoms. Polymorphic ventricular tachycardia was noted during the event. Further investigation revealed a normal QT interval, normal electrolyte panel, normal coronaries and severe left ventricular systolic dysfunction. Cardiac MRI revealed non-ischaemic cardiomyopathy. The patient was managed with heart failure and antiarrhythmic medications and an implantable cardioverter defibrillator. She remained symptom free at 6-month follow-up. This case highlights the importance of differentiating between cardiogenic syncope and epilepsy and reiterates the importance of re-evaluating a diagnosis of epilepsy when presentation is atypical or symptoms are refractory.
To evaluate the clinical characteristics and predictors of in-hospital mortality in patients with infective endocarditis at a tertiary care centre in Pakistan.
The cross-sectional study was conducted ...at the Aga Khan University Hospital, Karachi, from January 1, 2002, to December 31, 2006, and comprised 84 consecutive patients hospitalised with infective endocarditis,. All patients underwent verification of the diagnosis according to the Modified Duke criterion. Data was collected through a questionnaire and analysed using Student's t test, Chi square and Fisher's exact test. Univariate and multivariate logistic regression analysis was performed to assess predictors of mortality.
Of the total, 53(63%) patients were male and 31(37%) female. The mean age of the patients was 42+17 years. Overall, 34(41%) patients had rheumatic valve disease as a predisposing condition. The most commonly affected valve was mitral in 43(51%) patients, and the most commonly isolated organism was methicillin-resistant staphylococcus aureus in 12(14.3%). Overall in-hospital mortality was 27(32.1%), while 18(21%) patients, developed congestive cardiac failure, 15(18%) developed arrhythmias, 16(19%) developed peripheral embolism and renal failure was present in 38(54%). Besides, 17(20%) patients underwent surgical intervention. The final multivariate model that can be used to predict mortality in this study consisted of the presence of neurological complications (p <0.001) Odds Ratio 7.26, Confidence Interval (2.27-23.18), congestive cardiac heart failure (p <0.023) Odds Ratio 5.39, Confidence Interval (1.26-23.04), and arrhythmias (p <0.034) Odds Ratio 4.21, Confidence Interval (1.11-15.88).
Significant predictors of mortality in hospitalised patients with infective endocarditis in our study were the presence of neurological complications, congestive cardiac heart failure, and the presence of arrhythmias.
Hypertensive heart disease (HHD), one of the end-organ damage consequences of hypertension, is an important public health issue worldwide. Data on the HHD burden in the Eastern Mediterranean region ...(EMR) are scarce. We aimed to investigate the burden of HHD in the EMR, its member countries, and globally from 1990 to 2019.
We used 2019 Global Burden of Disease (GBD) data to report the HHD age-standardised prevalence, disability adjusted life years (DALYs), years of life lost (YLLs), and mortality, as well as HHD risk factors attribution percent with their 95% uncertainty interval (UI). Global data are reported alongside EMR data, and its 22 respective countries. We compared the burden of HHD by socio-demographic index (SDI), sex, age groups, and countries.
The age-standardised prevalence rate (per 100,000 population) of HHD was higher in the EMR (281.7; 95% UI: 204.5–383.4) in 2019, compared with the global prevalence (233.8; 95% UI: 170.5–312.9). The EMR age-standardised DALYs (per 100,000 population) for HHD in 2019 was 561.9 (361.0–704.1), compared with 268.2 (204.6–298.1) at the global level. There was an increase in HHD prevalence, reduction in mortality, and DALYs between 1990 and 2019 (4.01%, −7.6%, and −6.5%, respectively) in EMR. Among EMR countries, the highest versus lowest rates of age-standardised prevalence, mortality, and DALYs in 2019 estimate (95% UI) were in Jordan 561.62 (417.9–747.6) versus Saudi Arabia 94.9 (69.5–129.0); Afghanistan 74.5 (23.7–112.3) versus Saudi Arabia 4.3 (3.3–5.9); and Afghanistan 1374.1 (467.2–2020.7) versus Qatar 87.11 (64.40–114.29), respectively.
HHD remains a significant problem in the EMR, with a higher burden than global levels. Serious efforts toward high-quality management and prevention are strongly recommended. Based on this study, our recommendation for the EMR is to adopt effective preventive strategies. For example, promoting healthy dietary patterns and prompt screening for undiagnosed HTN in public places, promoting regular blood pressure measurements at home, and creating community awareness about early detection of HTN.

Vascular disease, manifesting as myocardial infarction and stroke, is a major cause of morbidity and mortality, especially in low- and middle-income countries. Current estimates are that only one in ...six patients have good adherence to medications and very few have sufficient health literacy. Our aim is to explore the effectiveness and acceptability of Prescription Interactive Voice Response (IVR) Talking Prescriptions (Talking Rx) and SMS reminders in increasing medication adherence and health literacy in Pakistani patients with vascular disease.
This is a randomized, controlled, single center trial. Adult participants, with access to a cell phone and a history of vascular disease, taking multiple risk-modifying medications (inclusive of anti-platelets and statins) will be selected from cerebrovascular and cardiovascular clinics. They will be randomized in a 1:1 ratio via a block design to the intervention or the control arm with both groups having access to a helpline number to address their queries in addition to standard of care as per institutional guidelines. Participants in the intervention group will also have access to Interactive Voice Response (IVR) technology tailored to their respective prescriptions in the native language (Urdu) and will have the ability to hear information about their medication dosage, correct use, side effects, mechanism of action and how and why they should use their medication, as many times as they like. Participants in the intervention arm will also receive scheduled SMS messages reminding them to take their medications. The primary outcome measure will be the comparison of the difference in adherence to anti-platelet and statin medication between baseline and at 3-month follow-up in each group measured by the Morisky Medication Adherence Scale. To ascertain the impact of our intervention on health literacy, we will also compare a local content-validated and modified version of Test of Health Literacy in Adults (TOFHLA) between the intervention and the control arm. We estimate that a sample size of 86 participants in each arm will be able to detect a difference of 1 point on the MMAS with a power of 90 % and significance level of 5 %. Accounting for an attrition rate of 15 %, we plan to enroll 100 participants in each arm (total study population = 200). We hypothesize that a linguistically tailored health IT intervention based on IVR and SMS will be associated with an improvement in adherence (to anti-platelet and lipid-lowering medications) and an improvement in health literacy in Pakistani patients with vascular disease.
This innovative study will provide early data for the feasibility of the use of IT based prescriptions in an lower middle incorme country setting with limited numeracy and literacy skills.
