Congestive heart failure: acute decompensation causes shortness of breath. Fluids builds up in the lung. Usually CHF from left ventricle disease so doesn’t pump well. Also from fluid overload (like in blood transfusions or IV fluids), severe high blood pressure, severe kidney disease, renovascular HTN. CHF from acute heart attack. Atrial fibrillation with fast heart beat can cause it. Shortness of breath is main symptoms. blood pressure can drop and kidneys function drops. Legs can become very swollen. From fluid build up, there is acute weight gain. Often requires hospitalization to improved blood pressure, reduce fluid, improve heart function, help oxygenation.

Endometriosis: endometrial glands and stroma that is present outside the uterus. Prevalence not known. Can be asymptomatic and found on autopsy and incidentally during surgery. But prevalence when involved with other diseases are such: 1% all women undergoing major gynecologic surgery; 1-7% tubal ligation; 12-32% reproductive age with pelvic pain undergoing laparoscopy; 9-50% laparoscopy for infertility; 50% teenagers laparoscopy for chronic pelvic pain or dysmenorrhea.
Risk factors: delayed pregnancy (so professional women might have it more). 25-35yo. Taller, thinner women. Ovarian steroids needed so rare in those menopausal or pre-menarche. Endometriosis might be a risk factor for developing ovarian cancer. The ovarian cancer risk is reduced with OCP but higher with HRT or tamoxifen.
Endometrial tissue goes on in descending order: ovaries, anterior and posterior cul-de-sac, posterior broad ligaments, uterosacral ligaments, uterus, oviducts, sigmoid colon and appendix, round ligament. Appendix in 2-4% cases. Has even been reported in breasts, spine, lungs, and extremities. Can cause adhesions.
Pain usually with menstrual period, but it can be continuous. Pelvic pain, dysmenorrheal, subfertility, deep dyspareunia, cyclical bowel or bladder symptoms, chronic fatigue. If under skin, bruising from the bleeding can be seen! On exam can mimic PID. The endometriosis tissue unlike that in the uterus contains fibrous tissue, cysts, and blood.
