WELCOME TO HCM,
as per the details you have give you father is suffering from multi organ failure . becoz he has elevated blood urea, serum creatinine
both are the parameters used to measure the kidney
function , his blood platelets are also low . but only with the vague details we cant comment on the health condition..we need further details like is he a smoker? alcoholic? hypertensive ? Diabetic? and also the bed side ECHO report. there is also a possibility of pulmonary embolism
so recognise the exact problem he needs all those details...
