Taking vital signs to heart

PETALING JAYA: Malaysians are having cardiovascular diseases significantly earlier than those in other high-income nations, say medical experts tracking trends of non-communicable diseases.

The mean age of Malaysian cardiovascular disease (CVD) patients were from 56 to 59, which is about 10 years younger than those in advanced countries, who tend to exhibit CVDs between 63 and 68 years.

This is the data from the National Health and Morbidity Survey in 2019, or in the Covid-19 pre-pandemic period.

UM Medical Centre (UMMC) senior consultant cardiologist Datuk Prof Dr Wan Azman Wan Ahmad said this in a recent presentation for the media on the rising burden of CVDs in Malaysia organised by IQVIA Asia Pacific, a global health intelligence organisation.

“It has been estimated that CVD-related deaths will reach approximately 31,000 cases annually by 2025 if no concrete measures are put in place to reduce CVD rates,” said Dr Wan Azman, adding that this would form about 55% of all non-communicable diseases related deaths in the country.

With the arrival of Covid-19 in Malaysia in 2020, CVDs still formed a substantial part of deaths, with ischaemic heart diseases and cerebrovascular diseases combining to contribute 20.2% of deaths in 2022, as per the data from the Statistics Department.

“CVDs account for the largest share in costs for hospitalisation (47.77% or RM1.01bil) and medication (46% or RM792mil) compared to other non-communicable diseases, while resulting in annual productivity losses of approximately RM4bil,” said Dr Wan Azman.

He said the most common risk factors for CVDs are uncontrolled blood sugar levels (diabetics), hypertension and high cholesterol (hypercholestrolaemia)

While monitoring blood sugar and blood pressure are relatively straightforward things, monitoring one’s cholesterol level, especially levels of the “bad” cholesterol otherwise known as the low-density lipoproteins (LDLs), has proven to be more challenging, for a variety of reasons.

A person with high cholesterol has no symptoms, he said, adding that a comprehensive blood test was the only way to detect it.

“What makes it more complicating is that while a person’s total cholesterol (combination of high-density lipoproteins and LDL) count may be fine, the percentage of LDL in the total cholesterol count may have breached risky levels,” added Dr Wan Azman.

Health Ministry family medicine specialist consultant Dr Sri Wahyu Taher who was another member of the panel at the event said blood pressure (BP) and blood sugar could be measured easily in public health clinics or general practitioners or at retail pharmacies.

“Checking for cholesterol is not as easy as there is a need to draw a blood sample from the vein to be tested in the laboratory,” she said.

Typically, LDL testing are part of a lipid panel test (that measures total cholesterol, breakdown between HDL and LDL, as well as triglycerides) that are done in comprehensive health screenings.

The challenge includes disseminating information that cholesterol screening is readily available even at government health clinics.

“It is not necessary for a person to go to the hospital to get a cholesterol test done,” added Dr Sri Wahyu.
