NORWALK - Doctors are warning residents across southwestern Connecticut to use caution while shoveling.

Dr. Jody Gerard, who works at St. Vincent's Medical Center, says the day after the storm she treated four patients for heart attacks. Gerard says blood can thicken in the cold weather, raising blood pressure and the risk for a heart attack.

Gerard says if you think you are at risk, you should avoid shoveling. However, if you are unable to escape the daunting task, Gerard says dress warmly and be sure to take your pulse.
