CAD

CAD stands for "control-alt-delete," the interrupt key sequence for the Windows operating system. By pressing the three keys simultaneously, the current process is interrupted (invoking task manager in Windows 95 systems and later).

Windows computer users, from IT professionals to novice users, may use CAD to refer to the key sequence. For example, if a user is complaining about a process that won't stop, an IT professional may send instructions that include the CAD function to help them quit an unresponsive program.

In the health industry, CAD stands for "coronary heart disease," which is the most common type of heart disease. CAD occurs when arteries supplying blood to the heart become narrowed and hardened from cholesterol and plaque clogging the inner walls, which can lead to chest pain or a heart attack.

Primarily, health professionals will use the acronym. However, people who have experience with CAD may also use it when describing their ailment. For example, after a recent doctor's visit, you may tell your brother the doctor told you that you have CAD and need to exercise more.
