Question

Arrange the sequence of steps in the development of heart failure?

Answer 1

The correct order is shown in the attachment below.

Heart attack or myocardial infarction is a medical situation which occurs when there is a decrease in the flow of blood towards the heart.

It usually starts with the deposition of substances like fats, cholesterol, et cetera which leads to the formation of plaque in the artery (especially those which feed coronary arteries).

The plaque or blockage reduces the flow of blood towards the heart.

As a result, the heart starting contracting more vigorously which increases the blood pressure and thickens the cardiac muscles.

With time, the efficiency of the heart decreases due to which less oxygen is reached to the heart and ultimately, a person experiences a heart attack.

Answer 2

This is the correct sequence of steps in the development of heart failure.

1. Fat deposits build up along artery walls

2.Blockage in artery obstruct blood flow and can cause heart attacks

3.Blood pressure increases and cardiac muscles thicken

4.Heart pumps blood less efficiently

5.Oxygen delivery is reduced and heart failure occurs
