Hardened plaque narrows the coronary arteries and reduces the flow of oxygen-rich blood to the heart. If the plaque ruptures, a blood clot can form on its surface. A large blood clot can mostly or completely block blood flow through a coronary artery.oronary heart disease (CHD) is a disease in which a waxy substance called plaque (plak) builds up inside the coronary arteries. These arteries supply oxygen-rich blood to your heart muscle. When plaque builds up in the arteries, the condition is called atherosclerosis (ATH-er-o-skler-O-sis).
SUBTOTAL Function Argument Definition. function_num: This argument can be the numbers 1 to 11 which means that it will include hidden worksheet row values when calculating or 101 to 111 which means it will ignore hidden row values when calculating. The numbers indicate what type of calculation it will perform like a sum or an average.
2) You can use SUBTOTAL to ignore values in hidden rows. Often, we use hide rows feature in excel to remove irrelevant items from view. You can use SUBTOTAL with special type codes so that values in hidden rows are neglected. For eg. SUBTOTAL(9,A1:A10) finds the sum of values in cells A1:A10 where as SUBTOTAL(109,A1:A10) will find sum of values in visible rows only.
