Sudden Drop in BP
axslinger99 posted:
I am a Cardiac patient. I had single bypass in 2009 at the age of 48. I am now 52. I'm in good health, not to much over-weight (I'm 5'8" and about 180) but I carry it well.

I didn't have a heart attack so I don't have any heart muscle damage. I'm on lisinopril for hyptertension and Metoprolol to regulate heart rate.

I had an angiogram about 3 months ago and they gave me a clean bill of health; the heart looks good and the graft looks good.

Normally, I have hypertension. Even on my meds, it's not uncommon for my BP to hit 150/90.

This morning, I woke up and checked my email first thing. While reading the screen, I started feeling "funny". Couldn't focus on the screen. Shortly after, I started sweating and my vision began to fade.

I put on my BP cuff and took my BP. It was around 77/42. I didn't really have any other symptoms other than the back of my neck was stiff/sore and I almost felt a little nauseous. My vision was like "grayed out"...I knew I was on the verge of losing consciousness.

I called a friend to come and take me to the ER. By the time she shot here, I had started to recover. I drank some salt water to get my BP back up and it seemed to help. Got it back up to 128/80.

My question is, what kind of event was this? I haven't been sleeping very well; 4-5 hours a night, max. could this have been a heart attack?

"Could this have been a heart attack?"

Realistically, there's no way to tell/know for sure via the Internet (which has serious limitations/restrictions).

And a heart attack (myocardial infarction, MI) can only be truly confirmed or ruled out with the appropriate diagnostics.

"I put on my BP cuff and took my BP. It was around 77/42."

Low blood pressure (hypotension is defined as being under 90/60.

The basics about blood pressure

As reported, the complex human body is usually able to keep blood pressure (BP) within safe/acceptable limits, but sometimes changes in lifestyle, health, side effects from prescription drugs, or changes in metabolism, make this difficult. This can cause the BP to become consistently higher or lower than normal, or just spike up and then drop down.

Compensatory mechanisms that control BP involves changing the diameter of veins and small arteries (arterioles), the amount of blood pumped out from the heart per minute (cardiac output), and the volume of blood in the vessels.

Most important, coronary artery bypass graft (CABG) surgery is only a clever way of temporarily circumventing the problem (atherosclerosis), as it doesn't treat the disease process and what drives the progression.

Best of luck down the road of life.

Good to know, for the primary and secondary prevention of heart attack and brain attack

Epidemiologic studies (EDS) have revealed risk factors (encompasses some new, novel or emerging) for atherosclerosis, which includes age, gender, genetics (gene deletion, malfunction or mutation) , diabetes (considered as being the highest risk factor), smoking (includes second/thirdhand), inactivity, obesity (a global epidemic, "globesity"), high blood pressure (hypertension), Low HDL (now questionable, according to recent studies) high LDL, small, dense LDL, RLP (remnant lipoprotein), high Lp(a), high ApoB, high Lp-PLA2, high triglycerides, HDL2b, high homocysteine (now questionable), and high C-reactive protein (CRP/hs-CRP).
