I am 30 male Was smoking and drinking(light) for 5 years left  all bad habits since last one year. My cholestrol and trigli are deranged badly but hdl is good. I sometime feel breathlessness while sleeping I wake up suddenly specially in the morning time and feel like my heart is going to collapse any time I don't have any  symptoms like chest pain except breathlessness sometimes. One day I even fainted for like 1 minute and got consciousness and was fine later. Is it sign of heart disease
