The INR clinic serves to optimize therapeutic anticoagulation for patients who are on Warfarin.


Anticoagulants, known as blood thinners, such as Warfarin are medications prescribed for the prevention or treatment of blood clots by slowing down the formation of the blood clots due to certain medical conditions or following procedures such as heart valve repair/replacement and Fontal/Bentall procedure.


For patients who are on Warfarin, it is crucial to regularly check and monitor their international normalised ratio (INR) – a test that measures the time it takes for blood to clot. The effects of Warfarin can vary significantly from one individual to another. Careful dosage adjustment is required based on INR, that checks for your response towards Warfarin. The dosage may change after each visit, according to the INR results and patient’s conditions, such as onset of any illnesses, recent hospitalisation, changes in medication or lifestyle changes. Hence regular monitoring is required, as advised by the doctor and INR Clinic staff. INR blood test is offered by IJN Laboratory and same-day dosage adjustment of Warfarin and monitoring is carried out by the INR Clinic staff.


The primary objective of our INR clinic is to provide close monitoring while you are on warfarin therapy and maintaining a balance between preventing blood clot formation and minimizing the risk of bleeding.


Kindly bring along your Warfarin Record Book each time you attend the INR clinic or a doctor’s appointment.

Heart Failure

Heart failure means the heart does not pump as well as it should during each heart beat. As a result, the heart cannot pump enough blood to meet the body’s needs.


Malaysia had one of the highest HF prevalence rates in Southeast Asia, with 721 cases per 100,000 persons in 2017, an increase of 7.7% from 669 cases per 100,000 persons in 1990. HF requires frequent hospitalisation and reduces life expectancy and quality of life.


Reference: Ong SC, Low JZ. Financial burden of heart failure in Malaysia: A perspective from the public healthcare system. PLoS One. 2023 Jul 5;18(7): e0288035. doi: 10.1371/journal.pone.0288035. PMID: 37406003; PMCID: PMC10321615.

How common is Heart Failure?

Heart failure becomes more common with increasing age. About 1 in 15 people aged 65-74 years have heart failure. This increases to about 1 in 15 of people aged 75-84 years, and to just over 1 in 7 people aged 85 years and above. It is uncommon in younger people.

Signs and symptom of Heart Failure

  • Shortness of breath (dyspnea) on exertion, and sometimes when lying down.
  • Reduced ability to exercise.
  • Persistent cough or wheezing with white or pink blood-tinge phlegm.
  • Swelling (edema) in legs, ankles, and feet.
  • Swelling of the abdomen (ascites).
  • Sudden weight gain from fluid retention.
  • Lack of appetite and nausea.
  • Irregular or rapid heartbeat.

What are the causes of Heart Failure?

Coronary artery disease is the most common cause. In this condition the blood flow to the heart muscle is reduced by narrowing of the coronary arteries that supply the heart muscle with blood and oxygen. The heart muscle may then not function as well as normal. Heart failure may develop after a heart attack (myocardial infarction), A heart attack is due to sudden blockage of a coronary artery that results in damage to part of the heart muscle.


Following a heart attack, scar tissue forms in the effected part of the heart muscle, the bigger area the heart attack, the bigger the damage and scarring, and the more likely the function of the heart is affected leading to heart failure.

Various others condition also cause heart failure. For example:


  • Disease of the heart muscle (cardiomyopathy)
  • Uncontrolled high blood pressure
  • Severe arrythmias
  • Drugs or chemicals that may damage the heart muscle e.g. alcohol excess, cocaine and some type of chemotherapy
  • Congenital heart defects
  • Viruses
  • Diabetes

Can Heart Failure be prevented?

Good blood pressure control is important if a person has high blood pressure. Prevent the development of coronary artery disease and heart attacks by controlling cholesterol levels and avoiding smoking. In patients with coronary artery disease, appropriate treatment can reduce the risk of heart attacks.


If heart attacks occur, early treatment can limit muscle damage and various medications after a heart attack can reduce the development of heart failure.

What is the aim of management for Heart Failure?

  • Preventing worsening of Heart Failure.
  • Reducing symptoms & hospitalisation due to heart failure and improving the quality of life.
  • Improving the survival of patients with heart failure.

What is the outlook (prognosis)

In general, the more severe the heart failure, the worse is the outlook. In many cases the symptoms remain stable for quite sometime (months or years) before deteriorating. In some cases the deterioration is more rapid and eventually leads to death.


Heart failure is a chronic disease needing lifelong management. However with treatment, a failing heart can improve and patients can feel better and live longer.

Treatment and Management of Heart Failure

    1. Diet –
      If patients are overweight, they should try to lose weight to reduce the extra burden on their heart. Patients also need to be on fluid restriction and follow a low salt diet.
    2. No Smoking –
      The chemicals in tobacco cause blood vessels to narrow (constrict) which can make heart failure worse. Smoking is also likely to make coronary artery disease worse.
    3. Exercise –
      For most people with heart failure, regular exercise is advised.
    4. Monitor his weight regularly –
      This will let patients know if they are retaining fluid particularly if there is a weight gain of more than 2kg over 1-3 days.
    5. No alcohol –
      Do not drink too much or do not drink any alcohol at all.

Other treatment for underlying condition may be advised, for example:

  • Treatment to lower blood pressure, if a patient has a high blood pressure.
  • Treatment to slow down the progression of coronary artery disease if this the cause of the heart failure, for example lowering a high cholesterol level.
  • Coronary artery bypass may be an option in some cases of coronary artery disease.
  • Surgery to replace or fix a heart valve, if a damaged heart valve is the cause of the heart failure.
  • Heart transplant is an option in some cases with severe heart failure, not responding to the usual treatments.
