Yes, metformin generally has beneficial effects on the heart, reducing cardiovascular risks like heart attack and heart failure in type 2 diabetes patients by improving heart metabolism, reducing inflammation, and protecting against damage, though it's generally considered safe and can even improve outcomes in heart failure. While evidence points to its protective role, research continues to clarify its mechanisms and optimal use, especially after events like heart attacks, with some studies showing promise in limiting damage.
Metformin therapy may reduce the high risk of cardiovascular events in pre‐DM patients by reducing coronary endothelial dysfunction. Metformin is efficacious, well tolerated, and has potential long‐term benefits in the improvement of body composition and inflammation markers in such patients.
Metformin may also be used for gestational diabetes, polycystic ovary syndrome (PCOS), and the prevention of type 2 diabetes/prediabetes. Common side effects of metformin can include dizziness, irregular heartbeat, feeling cold, tiredness, and more.
Under certain conditions, too much metformin can cause lactic acidosis. The symptoms of lactic acidosis are severe and quick to appear, and usually occur when other health problems not related to the medicine are present and are very severe, such as a heart attack or kidney failure.
(HealthDay News) — Among patients with type 2 diabetes, vildagliptin lowers blood pressure and elevates heart rate, while metformin increases heart rate and has no effect on blood pressure during intraduodenal glucose infusion, according to a study published in Diabetes Care.
In general, adults with diabetes are twice as likely to have a heart attack or stroke as those who don't have diabetes. Another factor that increases the risk of silent heart attack for people with diabetes is neuropathy. A common complication of diabetes, neuropathy refers to nerve damage.
Who can and cannot take metformin
Metformin not only reduces the incidence of cardiovascular diseases (CVD) in T2D patients, but also reduces the burden of atherosclerosis (AS) in pre-diabetes patients. Vascular smooth muscle cells (VSMCs) function is an important factor in determining the characteristics of the entire arterial vessel.
The symptoms – chest pain, tightness, and shortness of breath – can be similar, though. Sometimes, when arteries become completely blocked, a new blood supply develops around the blockage. This new blood supply, called collaterals, won't deliver as much blood to your heart.
Many medicines are available to treat coronary artery disease, including: Cholesterol medicine. Your healthcare professional might recommend this type of medicine to lower "bad" LDL cholesterol and reduce plaque buildup in the arteries. Such medicines include statins, niacin, fibrates and bile acid sequestrants.
Common alternatives to metformin include glucagon-like peptide-1 (GLP-1) agonists, sodium-glucose transport 2 (SGLT2) inhibitors, and dipeptidyl peptidase-4 (DPP-4) inhibitors. Less often, thiazolidinediones or sulfonylureas are used as an alternative to metformin.
"Metformin, however, can cause lactic acidosis in conditions where lactic acid production is high and the disposal of lactic acid is reduced. In conditions such as circulatory failure, sepsis, and anoxia or hypoxia, metformin use may result in lactic acidosis and should be avoided.
Foods to Avoid While Taking Metformin
How long to take it for. Treatment for diabetes is usually for life. But if your kidneys are not working properly, your doctor will tell you to stop taking metformin and switch you to a different medicine. Do not stop taking metformin without talking to your doctor.

Diabetes Complications Explained
In general, you'll want to eat whole foods like fruits, veggies, lean proteins, healthy fats, and whole grains. These foods can promote weight loss, and sticking to them can help you avoid the types of foods that may make side effects worse.
Additional in vivo research is necessary to fully understand the clinical implications of this drug-drug interaction. It is recommended that the co-administration of metformin HCl with omeprazole and lansoprazole be closely monitored, and simultaneous intake of metformin HCl with omeprazole and lansoprazole be avoided.
