Heart Truths

​Prof Tan Huay Cheem Director, NUHCS, a key contributor of “The Healthy Hearts, Healthy Ageing Asia Pacific Report” commented on the findings and provided tips for cardiovascular health.  

Focus on preventive care to improve heart health: Report

An article on how Asia-Pacific countries should move away from an acute care model to a preventive one in order to reduce the incidence of cardiovascular diseases.
 
Professor Tan Huay Cheem, Director, NUHCS, said that governments across the world have important roles to play in cardiovascular disease prevention. He also said the first step is to provide evidence-based, cost-effective care. Second step is to put in place legislative measures and finally, government should work towards improving the general economic health of the population.  

Choosing the right test for heart disease

A contributed article by Professor Tan Huay Cheem, Director, NUHCS, and Professor Terrance Chua, Medical Director, NHCS, on how to choose the right test for heart disease.
 
While there are many tests for heart disease, each does have its own strengths and limitations while different tests are also recommended for different situations. Ultimately, choosing a test should depend on whether it can lead to better recovery outcomes.

Switch to healthier fats

Professor Tan Huay Cheem, Director and Senior Consultant, National University Heart Centre, Singapore commented on the cardiovascular risks of regularly consuming fried foods (which contain trans fats) and saturated fats like palm oil. Notwithstanding the data, he qualified that a person’s cardiovascular risk is ultimately dependent on multiple factors, with diet being one aspect. Pointing out that people may not realise they are consuming far larger amounts of saturated fats and trans fat than the recommended daily allowances, he mentioned that heart patients (in particular) should be consuming less trans and saturated fats. ​

Cholesterol-lowering drug cuts heart attack, stroke risks: Study

A large-scale international clinical trial has found that alirocumab, a cholesterol-lowering drug sold here, is effective in reducing heart attack and stroke risk. The trial involved about 19,000 patients from 58 countries including Singapore, who had experienced a heart attack or unstable angina that required hospitalisation. Though the drug was approved by the Health Science Authority in 2017, Associate Professor Poh Kian Keong from the National University Heart Centre, Singapore (NUHCS) remarked that the take-up rate has been low alluding it to two reasons – (1) effects on cardiovascular morbidity and mortality had not been determined and (2) expensive cost of drug.

Mr Koh Chye Choon, 65, a patient of the NUHCS suffered a heart attack in February this year. He was diagnosed with severe dyslipidaemia and coronary artery disease. Mr Koh could not be on statins therapy due to his intolerance to statins.  He was referred to A/Prof Poh Kian Keong who prescribed him alicumorab to reduce his LDL-C levels and cholesterol. Over six weeks, his blood cholesterol fell from 190mg/dL to 70mg/dL. 

你需要服用阿司匹林吗？(Should you use Aspirins?)

In recent years, aspirin has been found to prevent myocardial infarction and stroke.  Prof Tan Huay Cheem, Centre Director of National University Heart Centre, Singapore, gave advice on primary and secondary prevention.
 
Those with diabetes, high blood fat or high blood pressure, or those who smokes or have a family history of early heart attack, should consider taking aspirin for primary prevention. If you do not have the risk factors listed above, it is not recommended to take aspirin.
 
Secondary prevention of cardiovascular disease refers to preventive measures for patients who have had myocardial infarction, ischemic stroke, bypass surgery, angina pectoris or peripheral vascular disease. Aspirin benefits these patients and is used to prevent recurrence and progression of the disease, improve prognosis, and reduce the rate of death and disability. 

Caffeine increases risk of Cardiovascular Disease (咖啡因提高心血管疾病风险)

An article which reports that excessive caffeine can increases the risk of cardiovascular diseases. A survey done by the University of South Australia showed that drinking six or more cups of coffee a day would increase the risk of heart disease.  

Professor Tan Huey Cheem, Director, NUHCS, mentions that while caffeine gives a refreshing effect, it also causes an increase in blood pressure and rapid heartbeat. Prof Tan also mentions that some caffeine drinks do negatively affect health such as energy drinks that are high in sugar and calories. 

做伏地挺身能促使心脏健康？ (Doing push-ups promotes heart health?)

​Professor Tan Huay Cheem, Director of National University Heart Centre, Singapore provided his expert opinion on push-ups and heart health. He shared that all forms of exercise are associated with improved cardiovascular health. The recommendations for improved heart health should be a mix of aerobic exercise and resistance weight training. Push-ups should be viewed as part of an overall balanced exercise programme.

Women likelier to dismiss heart attack symptoms: Survey

​Assistant Professor Chan Wan Xian, Senior Consultant, National University Heart Centre, Singapore (NUHCS) spoke at the Go Red for Women Luncheon 2019 organised by the Singapore Heart Foundation. She shared that while heart disease is commonly the result of an obstruction in the blood vessels, women are twice as likely as men to suffer from non-obstructive heart disease. She cited an example of takotsubo cardiomyopathy also known as “broken-heart syndrome” which is related to acute stress or emotional shock, possibly due to a surge in adrenaline, leading to heart failure. 

What is the function of an AED?

​A contributed article by Professor Tan Huey Cheem, Director, NUHCS, on out-of-hospital cardiac arrest (OHCA) being a worldwide public health problem, the function and effectiveness of the automated external defibrillator (AED), when and how to use the AED and the locations of AED. 

Is ‘premature beat’ dangerous

​A contributed article by Prof Tan Huay Cheem, Director, NUHCS, shared that asymptomatic premature beats are common and usually not harmful. It mainly occurs in two forms – premature atrial contractions (PAC) and premature ventricular contractions (PVC), with the latter happening more frequently. While it is normal for PVC to occur during daily activities, PVC may lead to cardiomyopathy if it occurs often. Early diagnosis can be made using electrocardiograms or other medical technology. One does not need medication if there is no heart disease linked to the contractions.

Scheme gives early help to those at risk of heart problem

An article on NUHCS working to reduce the number of people in Singapore with serious heart problems by catching and treating patients before their condition blow up. NUHCS are working with polyclinics to identify patients that doctors think may be at risk of cardiovascular diseases.

Pulmonary hypertension patients hope for more understanding from the public

An article on pulmonary arterial hypertension and how it is as serious as cancer. It is hereditary for some patients, some of the other causes are still unknown. Dr. Low Ting Ting, consultant, Department of Cardiology, NUHCS, says that most patients are between the ages of 30 and 50 years old. As the symptoms are similar to those of other diseases, and patients and family doctors do not understand PAH, it may lead to delay in treatment.

According to data published by NUHCS, 45% of NUHCS’ 148 patients have died within 10 years of illness in the past 14 years.

癌症与心脑血管疾病有何关联 (What is the relationship between cancer and cardiovascular disease)

​Cancer and cardiovascular disease are the top two killer diseases in Singapore. Prof Tan Huay Cheem, Director of NUHCS shared that many clinical studies have shown a certain relationship between the two diseases, such as common risk factors and how they affect each other during treatment the process. Cardiovascular risk factors for cancer occurrence can be generally divided into controllable and uncontrollable categories. Controllable factors include smoking, hyperlipidaemia, hypertension, and diabetes, while the uncontrollable factors include age, gender and ethnicity. 

Indians at Heart Risk

A contributed article by Dr Devinder Singh, Senior Consultant, Department of Cardiology, NUHCS, about cardiac arrhythmias and how Indians are more at risk of stroke associated with atrial fibrillation. The article also explains the cardiovascular system to help readers understand how cardiac arrhythmias occur.
