Researchers on the Stroke Research and Prevention Group (HKU Stroke), Department of Medicine, School of Clinical Medicine, LKS Faculty of Medicine, The University 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 threat components, particularly hypertension.
Stroke is the second commonest explanation for demise and a number one explanation for incapacity on the earth. Although the general incidence of stroke has declined in high-income nations, the incidence of stroke among the many youthful populations has been rising globally. However, the epidemiology of ‘younger stroke’ in Hong Kong stays unsure.
Using the Clinical Data Analysis and Reporting System of Hospital Authority, the analysis workforce analyzed the traits 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 folks in 2001 to 48.3 per 100,000 in 2011 and 55.7 per 100,000 in 2021 (Figure 1). Although the whole variety of new stroke circumstances admitted to hospitals underneath Hospital Authority remained related at round 13,500 – 14,000 per yr in the course of 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 components of younger stroke, the research additionally adopted up with a cohort of 431 stroke sufferers aged from 18 to 55 years who had been admitted to Queen Mary Hospital and Ruttonjee Hospital of Hong Kong between September 2019 and August 2022. Among them, 53% had hypertension, 44% had hyperlipidemia, 26% had a smoking historical past, 19% had been overweight, and 17% had diabetes (Figure 2). Among these with hypertension, hyperlipidemia and diabetes, 33%, 64% and 23% had been newly identified in the course of the stroke admission respectively.
In a separate research, the place 284 apparently wholesome Hong Kong Chinese aged 40 to 65 years obtained 24-hour blood stress monitoring, roughly 40% had been identified with hypertension. Their common every day sodium consumption was estimated at 14g in males and 13g in girls, far exceeding the World Health Organization’s suggestions of not more than 5g per day by 2.8 occasions and a couple of.6 occasions respectively. Moreover, it was famous that sodium consumption strongly correlated with systolic and diastolic blood stress in addition to 10-year projected stroke threat.
‘These alarming findings name for stronger consciousness and management of vascular threat components resulting in stroke, particularly among the many youthful generations,’ commented Dr Gary Lau Kui-kai, Director of HKU Stroke who leads the research. ‘Hypertension is the main modifiable threat issue of stroke and former research have proven that with each 20mmHg enhance in systolic blood stress or 10mmHg enhance in diastolic blood stress, there’s a 30-50% elevated threat of stroke. Consistent with different research, our findings present that Chinese folks are likely to have a really excessive sodium consumption, which is immediately correlated with blood stress and likewise projected stroke threat. Hypertension, hyperlipidemia and diabetes are sometimes the results of poor life-style and dietary practices and measures to regulate for these vascular threat components by a greater weight-reduction plan with considerably decrease sodium consumption, common train and smoking cessation is strongly really helpful for stroke prevention.’
Our outcomes are worrying as strokes are related to a excessive likelihood of incapacity and demise. Stroke additionally has profound psychological and social penalties. This is particularly the case for younger people, who are sometimes bread-winners and have to maintain each older and youthful members of the family. Our analysis additionally confirmed that roughly 30% of stroke survivors in Hong Kong endure from moderate-severe melancholy, which is in step with different research. The sociopsychological impression of stroke is thus removed from negligible.”

It is essential for members of the general public to know the signs of stroke, such that they might search immediate medical consideration when wanted. Delays in searching for care or not searching for take care of stroke sufferers could possibly 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 final result and any delay in searching for care would severely jeopardize stroke affected person’s eligibility for therapy. The FAST slogan is often used to remind the group of the signs of stroke and what to do when stroke is suspected. FAST stands for Facial weak point, Arm weak point, Slurring of speech after which it is Time to name for assist or dial 999.
