1. Age:

Age of the patient.

2. Anemia:

Anemia is the number of healthy red blood cells in your body is to low. Red blood cells carry to the level of oxygen to all of the body’s tissue, so a low red blood cell count indicates that the amount of oxygen in your blood is lower than it should be

3. Creatinine phosphokinase: The level of the creatine phosphokinase in the blood in mcg/L. When the total CPK level is very high, it most often means there has been injury or stress to muscle tissue, the heart, or the brain. Muscle tissue injury is most likely. When a muscle is damaged, CPK leaks into the bloodstream. Finding which specific form of CPK is high helps determine which tissue has been damaged. (Range : Male = 21 to 232 IU/L , Female = 21 to 215 IU/L )

4. Diabetes:

Diabetes is the disease that occurs when your blood glucose, also called blood sugar, is too high. Glucose of blood is a main source of energy and its come from the eating of food.

5. Ejection fraction:

Ejection fraction is a measurement of how much blood the left ventricle pumps out with each contraction. A normal ejection fraction is more than 55%. This means that 55% of the total blood in the left ventricle is pumped out with each heartbeat. Heart failure with reduced ejection fraction happens when the muscle of the left ventricle is not pumping as well as normal. The ejection fraction is 40% or less.

(Ranges from 55% to 70%. )

6. High blood pressure: High blood pressure, or hypertension, occurs when your blood pressure increases to unhealthy level. Your blood pressure measurement considers how much blood is passing through your blood vessels and the amount of resistance the blood meets while the heart is pumping.

7. Platelets:

Platelet count of blood in kilo platelets/mL. Increased platelet activation and aggregation are involved in the pathogenesis of elevated blood pressure, which is also associated with hypertensive risk factors.

8. Serum creatinine:

The level of serum creatinine in the blood in mg/dL. Background and Purpose Elevated serum creatinine has been associated with increased mortality in hypertensive persons, the elderly, and patients with myocardial infarction or stroke in whom cardiovascular disease is the major cause of death.

(Range : Male = 0.74 to 1.35 mg/dL (65.4 to 119.3 micromoles/L)

Female = 0.59 to 1.04 mg/dL (52.2 to 91.9 micromoles/L) )

9. Serum sodium:

Sodium helps keep a normal balance of fluid in your body. Patients with heart failure need to follow a low-sodium diet because it helps control symptoms of heart failure and prevent other heart problems. Excessive sodium intake is linked to water retention, and it is also a risk factor for high blood pressure. Both excessive sodium intake and high blood pressure are major risk factors for developing heart failure, and for causing complications in those with existing heart failure. (Range : 135-147 mmol/L )

10. Gender:

The sex of the patient .

11. Smoking:

when you breathe in cigarette smoke, the blood that is distributed to the rest of the body becomes contaminated with the smoke's chemicals. These chemicals can damage to your heart and blood vessels

12. Time:

It is the time of the patient's follow-up visit for the disease in months

13. Death event:

If the patient deceased during the follow-up period
