My coughing is getting worse, late night cough n morning, is it because my mild asthma, or my borderline heart function ef 49, or my moderate eccentric regurgitation of mitral valve?

Please describe the quality of the cough ,e.g. dry or wet. An evaluation is recommended. A COVID 19 screening test may be helpful. Watch for signs of shortness of breath and fever. If you experience fever, an infection is a likely cause and this can trigger an asthma attack. Please follow up with your physician and a Healthtap consult is available.
