Researchers on the Stroke Analysis and Prevention Group (HKU Stroke), Division of Medication, Faculty of Scientific Medication, LKS School of Medication, The College of Hong Kong (HKUMed) discovered that the incidence of ‘younger stroke’ (strokes occurring in people aged 18 to 55 years) has elevated by 30% in Hong Kong from 2001 to 2021, thus referred to as for higher management of vascular danger elements, particularly hypertension.
Stroke is the second most typical reason behind demise and a number one reason behind incapacity on this planet. Though the general incidence of stroke has declined in high-income international locations, the incidence of stroke among the many youthful populations has been rising globally. Nevertheless, the epidemiology of ‘younger stroke’ in Hong Kong stays unsure.
Utilizing the Scientific Knowledge Evaluation and Reporting System of Hospital Authority, the analysis crew analyzed the tendencies of stroke in Hong Kong from 2001 to 2021 and located that the crude incidence of younger stroke has sharply elevated from 39.1 per 100,000 individuals in 2001 to 48.3 per 100,000 in 2011 and 55.7 per 100,000 in 2021 (Determine 1). Though the whole variety of new stroke circumstances admitted to hospitals below Hospital Authority remained comparable at round 13,500 – 14,000 per 12 months through the previous 20 years, the variety of younger stroke circumstances elevated from 1,531 in 2001, to 2,028 in 2021.
To determine the danger elements of younger stroke, the examine additionally adopted up with a cohort of 431 stroke sufferers aged from 18 to 55 years who have been admitted to Queen Mary Hospital and Ruttonjee Hospital of Hong Kong between September 2019 and August 2022. Amongst them, 53% had hypertension, 44% had hyperlipidemia, 26% had a smoking historical past, 19% have been overweight, and 17% had diabetes (Determine 2). Amongst these with hypertension, hyperlipidemia and diabetes, 33%, 64% and 23% have been newly identified through the stroke admission respectively.
In a separate examine, the place 284 apparently wholesome Hong Kong Chinese language aged 40 to 65 years obtained 24-hour blood strain monitoring, roughly 40% have been identified with hypertension. Their common each day sodium consumption was estimated at 14g in males and 13g in ladies, far exceeding the World Well being Group’s suggestions of not more than 5g per day by 2.8 instances and a couple of.6 instances respectively. Furthermore, it was famous that sodium consumption strongly correlated with systolic and diastolic blood strain in addition to 10-year projected stroke danger.
‘These alarming findings name for stronger consciousness and management of vascular danger elements resulting in stroke, particularly among the many youthful generations,’ commented Dr Gary Lau Kui-kai, Director of HKU Stroke who leads the examine. ‘Hypertension is the main modifiable danger issue of stroke and former research have proven that with each 20mmHg improve in systolic blood strain or 10mmHg improve in diastolic blood strain, there’s a 30-50% elevated danger of stroke. According to different research, our findings present that Chinese language individuals are likely to have a really excessive sodium consumption, which is instantly correlated with blood strain and likewise projected stroke danger. Hypertension, hyperlipidemia and diabetes are sometimes the results of poor way of life and dietary practices and measures to regulate for these vascular danger elements via a greater food regimen with considerably decrease sodium consumption, common train and smoking cessation is strongly beneficial for stroke prevention.’
Our outcomes are worrying as strokes are related to a excessive probability of incapacity and demise. Stroke additionally has profound psychological and social penalties. That is particularly the case for younger people, who are sometimes bread-winners and have to care for each older and youthful relations. Our analysis additionally confirmed that roughly 30% of stroke survivors in Hong Kong endure from moderate-severe despair, which is per different research. The sociopsychological impression of stroke is thus removed from negligible.”

It’s essential for members of the general public to know the signs of stroke, such that they may search immediate medical consideration when wanted. Delays in looking for care or not looking for look after stroke sufferers may very well be detrimental. Time is mind and for each minute that stroke shouldn’t be handled, it has been estimated that as much as 1.9 million mind neurons could also be misplaced. Earlier therapy for stroke is related to higher end result and any delay in looking for care would severely jeopardize stroke affected person’s eligibility for therapy. The FAST slogan is usually used to remind the group of the signs of stroke and what to do when stroke is suspected. FAST stands for Facial weak spot, Arm weak spot, Slurring of speech after which it is Time to name for assist or dial 999.
