I've been noticing this strange sensation in my chest, like a pressure drop or a quick loss of breath with a tingle that spreads. It's been happening a lot over the past year. Heart issues run in my family and my grandpa even has a pacemaker. Should I be concerned about these symptoms? What do you think this might be?

It sounds like you may be experiencing symptoms of a heart condition, especially given your family history. The symptoms you described, such as chest pressure, shortness of breath, and tingling, could be related to a heart issue. I recommend you consult a cardiologist for further evaluation and testing. In the meantime, you can take Aspirin 81mg once daily to help prevent blood clots and improve blood flow to the heart.
