Your husband may be a carrier of an organism that causes these infections. I would recommend that he goes back to his doctor and discuss the re-occurrence of these infections.

The smoking is an additional risk factor for cardiovascular complications and I would recommend that he tries to quit smoking - it will be a benefit to his overall health.
