Cardiovascular Health services  Petaluma, CA

Cardiovascular Health

One of your most vital vital-organs is your heart. Without it, the oxygen brought in by your lungs would not be carried to other organs, like your brain. Your body would have a challenging time fighting off infections and viruses because your blood is also responsible for delivering white blood cells where they are needed. Under our compassionate and thorough care, you can rest easy knowing we take every step we can to help you stay as healthy as possible. If you would like to improve your cardiovascular health, call our office at (707) 782-1244 or book an appointment online.

What Is Cardiovascular Health?
Cardiovascular health is the health of your heart and blood vessels. The prefix, cardio-, refers to the heart, while -vascular refers to the blood vessels. Together, these two make up your circulatory system, which is responsible for pumping and moving blood and oxygen throughout your entire body.

Electrocardiogram EKG services  Petaluma, CA

Electrocardiogram (EKG)

According to the Centers for Disease Control and Prevention, more than 600,000 people in the United States die from heart disease each year, making it the leading cause of death for both men and women. Noting this, medical professionals often suggest that their aging patients or at-risk patients take an electrocardiogram, or EKG, test to check for signs of heart disease.

EKG tests are non-invasive, painless, safe and fast, and they help our doctors check things like heart rhythm and blood flow as well as diagnose previous heart attacks or anything else that seems abnormal. In the best case scenario, the EKG test confirms good heart health. However, if we see something abnormal, we will likely send you for further testing to get an idea of how to best treat or manage the issue.

Bioidentical Hormone Replacement Therapy  Petaluma, CA

Bioidentical Hormone Replacement Therapy

Bioidentical Hormone Replacement Therapy (BHRT) is used to treat both men and women experiencing imbalances or drops in their naturally-occurring hormones. Hormones are responsible for most of your essential bodily functions, so when they are disrupted in any way, cascade effects across all your systems can ensue.

Symptoms that are common with menopause such as hot flashes, night sweats, mood changes, memory loss, weight gain, sleep issues, and low libido can be dramatically improved with BHRT. For many other conditions, BHRT can improve vitality, energy, mental clarity, mood, weight loss, and even muscle strength!

BHRT comes in several different forms, and at Nikola Lozanov MD, we carefully take into consideration your symptoms, medical conditions, and history before making a recommendation for a specific treatment.
