According to him, at the age of 40 people are able to “feel and understand” if they have heart problems.

“I had patients of all ages: 35-year-olds, 45-year-olds. They came and said: “Doctor, you know, it happens to me - once, once, once, my heart suddenly flutters and almost approaches my throat,” the cardiologist said.

The specialist added that such short-term symptoms are significant and attention should be paid to this.
