The phrase heart failure sounds like the heart has stopped. It has not. It means the heart is not pumping efficiently enough to meet the body's demands, and that is a spectrum, not a verdict. Many patients live active lives for decades with well managed heart failure.
Understanding what is happening makes the treatment make sense, and patients who understand it stay out of hospital far more successfully.
What Is Actually Failing
The heart is a pump. In heart failure it either cannot contract forcefully enough, or it cannot relax and fill properly. Both leave blood backing up behind the heart and insufficient flow ahead of it.
Doctors describe this using ejection fraction, the percentage of blood pushed out with each beat. Normal is roughly fifty five to seventy percent. Reduced ejection fraction heart failure means a weakened squeeze. Preserved ejection fraction heart failure means a stiff heart that pumps normally but fills poorly, and it is increasingly common in older patients with long standing hypertension.
The Symptoms and Why They Happen
Every classic symptom traces back to fluid in the wrong place or insufficient flow to muscles.
- Breathlessness on exertion: fluid congesting the lungs
- Waking at night gasping: fluid redistributing when you lie flat
- Needing extra pillows: the same mechanism, which is why doctors ask how many pillows you sleep on
- Swollen ankles and legs: fluid pooling with gravity
- Fatigue out of proportion to activity: reduced flow to working muscle
- Rapid weight gain over days: retained fluid, not fat
That last one is the most useful early warning, and the most overlooked.
How It Gets Diagnosed
Diagnosis combines symptoms with objective evidence, because breathlessness has many causes and lung disease often coexists.
- Echocardiogram: the central test, measuring ejection fraction and valve function
- BNP or NT proBNP blood test: raised when the heart is under stretch, useful for separating cardiac from lung causes
- ECG: shows rhythm problems and past infarction
- Chest X ray: shows congestion and heart size
- Blood tests: kidney function, thyroid, haemoglobin, all of which affect management
Finding the cause matters as much as the diagnosis. Previous heart attacks, uncontrolled blood pressure, valve disease, thyroid disorders and alcohol are all treatable contributors. Coronary disease is common enough that angiography is often part of the workup.
Treatment Has Changed Substantially
Heart failure with reduced ejection fraction is now treated with a combination of four drug classes, and the combination is more effective than any single agent. Patients started on all four appropriately live longer and are admitted less.
The reason your cardiologist keeps adding tablets is not that you are getting worse. It is that each class works on a different mechanism, and the goal is to get all of them on board at tolerated doses. Some of them, particularly beta blockers, may make you feel slightly worse for a fortnight before you feel better.
Ongoing heart failure management involves regular dose adjustment based on blood pressure, heart rate and kidney function, which is why the follow up appointments are frequent early on.
The Daily Weight Check That Prevents Admissions
This is the single most valuable habit for a heart failure patient, and it costs nothing.
- Weigh yourself every morning, after using the bathroom, before eating, in similar clothing
- Write it down, or use a notebook kept with the scale
- A gain of more than two kilograms in three days means fluid is accumulating
- Contact your cardiologist at that point, not when you cannot breathe
Fluid builds up for days before it makes you breathless. Catching it early usually means a temporary increase in a diuretic tablet at home. Catching it late means an admission.
Salt, Fluid and Everyday Living
Salt causes the body to hold water, which is why restriction matters more here than in almost any other condition. Under five grams a day is the usual target, and the practical work is avoiding pickles, papads, packaged snacks, processed meats and restaurant food rather than the salt shaker.
Fluid restriction is not universal. It is advised for patients who retain fluid despite diuretics, typically one and a half to two litres daily including tea, coffee and soup. Do not restrict fluid on your own initiative, particularly in Chennai summers, without discussing it.
Exercise is now encouraged rather than avoided. Supervised cardiac rehabilitation with our physiotherapy department improves symptoms and quality of life measurably.
Warning Signs That Need Same Day Attention
Call your cardiologist or come in if you have:
- Breathlessness at rest or on minimal activity
- Waking at night unable to breathe
- Weight gain over two kilograms in three days
- Swelling extending up the legs or into the abdomen
- Chest pain, fainting, or a persistently racing irregular pulse
- Confusion or a sharp drop in urine output
Severe breathlessness at rest is an emergency. Our critical care unit and non invasive ventilation support handle acute decompensation around the clock.
Heart failure is a long term condition managed rather than cured, and the patients who do best are the ones who become expert in their own numbers: their weight, their blood pressure, their tablets and their limits. That knowledge is genuinely protective.
To arrange a heart failure assessment, contact the cardiology department at our T. Nagar hospital.
