Reproduced with permissionProf Tan Huay Cheem, Chairman of Singapore Heart Foundation, who is also Director of NUHCS, shared it is important for those with hypertension to maintain normal blood pressure during the pandemic. He said about 20% of Covid-19 patients in Singapore had pre-existing hypertension. Among the 23 deaths so far, 10 patients aged between 60 and 86 were reported to have a history of hypertension. Hypertension can result in complications such as coronary artery disease, heart failure, chronic kidney failure, abnormal heart rhythms and stroke, which can worsen the general health and immunity of Covid-19 patients, especially the elderly, he added.
In another article on – “Blood clots and Covid-19”, he said that coronavirus are well known to increase blood coagulability. This means blood clots tend to form more easily within the circulatory system with serious complications. In deep vein thrombosis, a clot forms in a vein deep in the body, often in the leg. If the clot travels to the lung, it could cause a pulmonary embolism – blocking of a major blood vessels and gangrenous toes. He emphasised the importance of monitoring Covid-19 patients for such potential complications.
