I received a diagnosis of crescendo angina.
So if I understand it right, the sequence of events was: malignant hypertension > for which you were given doxazosin > which caused some side effects, and then at one point you experienced severe crushing chest pain which spread to the jaw, neck and back. Later that chest pain was diagnosed as crescendo angina.
I don't know about the doxazosin triggering this crescendo angina, but a quick Google search reveals that a common cause of crescendo angina is atherosclerosis (plaque on the arteries), and in this case the pain arises when a blood clot lodges in these furred up, narrowed arteries of the heart, causing a partial or complete blockage of blood flow, which cuts of the oxygen to the heart muscle.
And elderly family member has been having episodes of this sort of angina pain, and refuses to see a doctor. Because angina and heart attack are related conditions, I thought I better do some research on this, to find out what might help. My assumption is that they have atherosclerosis causing the angina, but because they refuse to go to a doctor, this has not been confirmed.
But on the assumption that they have atherosclerosis, and then get blood clots lodging in the heart arteries every now and then, I reasoned that the following supplements might help mitigate the attacks:
Aspirin 300 mg — to thin the blood. Aspirin is often given during a heart attack to thin the blood, so that it flows better past the clot.
Bromelain 2400 GDU x 2 — helps dissolve blood clots (enables the body to produce plasmin, which helps to clear away the fibrin that holds blood clots together).
Rutin 500 mg — helps prevent blood clot form forming (inhibits an enzyme involved in blood clotting called disulfide isomerase).
Potassium nitrate 1,000 mg — dilates blood vessels, which creates better blood flow.
So I prepared a vitamin box which has all the above already placed in each box compartment, and they now take these supplements every time an attack occurs, which is about once every 3 months. In theory these supplements should help.
