Your Heart Has a Midlife Too.
Bring your earlier history and recent changes into the same conversation: pregnancy, menopause, test results and how you feel in everyday life.
Dear reader,
There is one place I want The HEART RESERVE Letter to begin:
Your heart has a midlife too.
For many women, the pieces of cardiovascular health have been kept apart. Pregnancy history may sit in records from years ago. Menopause may be discussed as symptoms. Blood pressure, cholesterol, and blood sugar may sit on separate pages. Changes in strength, recovery, or what ordinary effort costs may never reach the chart at all.
Midlife is a chance to bring those pieces together. Not to assume the worst. Not to chase a perfect score. Simply to see enough of the whole story to ask the next useful question.
What Changed?
Begin with one question.
“What has changed over the last five to ten years?”
The newest result is one moment. The direction across time can make the next question clearer.
You do not need a perfect timeline. Write down what you know, leave blanks where you do not, and bring questions about meaning to your qualified clinician.
The Heart Explanation
Heart health is not one number.
HEART RESERVE uses four simple questions to organize your heart story. It is a guide for conversation—not a diagnosis or score.
- FLOW
- Are there problems with blood pressure, cholesterol, plaque, or blood flow?
- BEAT
- What rhythm is the heart in—especially when symptoms happen?
- PUMP
- How does the heart squeeze, relax, and fill, and how well do its valves work?
- POWER
- What can the heart, lungs, blood vessels, and muscles do together when life gets harder?
These questions overlap, but they are not the same. A normal answer in one area does not answer the others.
The test translator
Heart tests, in plain English.
An EKG or heart monitor records rhythm. A heart ultrasound shows the heart’s structure, valves, pumping and filling. CT scans can look for plaque in the heart’s arteries. Exercise tests show how your heart and body respond to extra work. A normal result on one test does not mean everything has been checked.
Different question. Different test. Different answer.These are common examples, not a checklist. You may need none, one, or several. The right test depends on your symptoms, history, and the question your clinician is trying to answer.
Blood pressure and blood work
What it is: A blood-pressure cuff plus lab work such as cholesterol, ApoB, Lp(a), and blood sugar.The question it helps answer: Are there signs that my heart and arteries are under extra strain or more likely to develop plaque?
What it cannot tell you: These numbers cannot show whether plaque is already present or how well the heart is pumping.
CT scans of the heart’s arteries
What it is: A calcium scan measures calcium in plaque. A coronary CT angiogram (CCTA) uses injected dye to show plaque and narrowing.The question it helps answer: Is there visible plaque or narrowing in the arteries that feed my heart?
What it cannot tell you: These are different tests. A calcium scan can miss soft plaque, and a picture alone may not show whether blood flow is reduced.
EKG, also called an ECG
What it is: A quick recording of the heart's electrical pattern.The question it helps answer: What is my heart rhythm doing during these few seconds?
What it cannot tell you: It may miss a rhythm problem that happened yesterday—or happens tomorrow. It does not show plaque or how well the heart pumps.
The office EKG saw Thursday. The symptom happened Tuesday.Heart monitor
What it is: A Holter, patch, or event monitor worn for hours, days, or weeks.The question it helps answer: What is my rhythm doing when the fluttering, racing, or skipped beat actually happens?
What it cannot tell you: It does not show the heart valves or arteries. The monitoring time needs to fit how often the symptom happens.
Echocardiogram, or echo
What it is: An ultrasound movie of the heart muscle, chambers, and valves.The question it helps answer: Is my heart squeezing and filling well, and are the valves working properly?
What it cannot tell you: A normal echo does not mean the heart arteries are free of plaque.
The echo sees the pump. It does not clear the pipes.Stress test
What it is: A test that checks the heart’s response to exercise or to a medicine used for testing, sometimes with images.The question it helps answer: What happens when my heart works harder—and, on some stress tests, are there signs it may not be getting enough blood?
What it cannot tell you: There are different kinds of stress tests. A normal result does not prove there is no plaque or explain every symptom.
Heart-and-lung exercise test (CPET)
What it is: A supervised exercise test that measures breathing and oxygen use.The question it helps answer: How well do my heart, lungs, blood vessels, and muscles work together during exercise?
What it cannot tell you: A low result is not a diagnosis, and a watch estimate of VO₂ is not the same as a formal CPET. This test is not needed for everyone.
Being disease-free is not the same as being high-capacity.Start with the question, not the test. Your symptoms, history, and examination help a clinician decide what—if anything—comes next. New, severe, or worsening symptoms need prompt medical care.
One Thing to Know
History is relevant. It is not destiny.
Midlife is a useful time to check in on heart health. As periods change, blood pressure, cholesterol, and blood sugar can change too. Bring those results, your symptoms, history, and changes in what you can do to your clinician. Menopause itself is not a heart diagnosis or a deadline.
Certain pregnancy complications are associated with a higher probability of later cardiovascular risk factors and cardiovascular disease. That history may be important to carry forward, but it does not predict an individual woman's future or automatically determine testing or treatment.
One Thing to Build
Build the private starting point that fits your story.
Pregnancy history in Heart Story
Preserve what happened, what you remember, and what is still unclear before that part of the story disappears.
Add pregnancy history to my Heart StoryMy Heart Story
Organize current numbers, family history, menopause, symptoms, testing, and physical capacity.

One Thing to Prove
Match the evidence to the goal.
Decide with your care team how you will know whether the plan is helping. The free visit preparation guide helps you gather your notes and questions, at your own pace.
Proof does not mean collecting every possible number. It means deciding—with appropriate clinical guidance—what would show that the plan helped, then returning to that evidence over time.
From Lisa
I built HEART RESERVE because women deserve a way to connect their health across time—not another isolated number.
My hope is that each Letter makes one part of that story clearer and gives you one useful question to carry forward.
No fear. No miracle promises. Just clearer questions, credible evidence, and practical ways to build the heart you need now.
With care,
