Am certain that the factor that prevents us from finding fossils from the Precambian era is that Most rocks from that era are deeply buried. The precambrian is the informal name for the large expanse of time preceding the current Phanerozoic Eon. It began with the Earh's Formation about 4.5 billion years ago and lasted until the advent of multicellular life about 542 million years ago.

All living cells need energy to function in order for the chemical reactions occurring in the cells to take place. In humans this energy is obtained by breaking down organic molecules such as carbohydrates, fats and proteins.
During a myocardial infarction, proteins that are normally inside the cells leak into the plasma, due to loss of plasma membrane integrity.
<h3>Cardiac disorders and it's effects:</h3>
There are different types of cardiac or heart disorders that occurs due to different etiological origins.
Example of a cardiac disorder is the myocardial infarction.
Myocardial infarction is defined as the blockage of blood flow to the heart by the presence of blood clot.
This hinders the delivery of oxygen carried by the blood to tissue cells leading to apoptosis (which is a programmed cell death).
This will cause the plasma membrane of cells to lose its integrity leading to leaking of proteins into the plasma.
