Your Heart Has a Midlife Too.
Midlife is a chance to place pregnancy history, menopause, numbers, symptoms, testing, and physical capacity on one cardiovascular timeline—not a deadline, and not a verdict.
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 live in an obstetric record. Menopause may be discussed as symptoms. Blood pressure, lipids, and glucose 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 well do the heart muscle and valves squeeze, relax, and fill?
- 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 monitor looks at rhythm. An echo looks at the pump. A calcium scan or CCTA looks at the arteries. Stress testing and CPET show what happens during exercise. 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.
Calcium scan or CCTA
What it is: A calcium scan counts hardened plaque. A CCTA uses 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: The heart is watched while it works harder through exercise or medicine, sometimes with pictures.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 cardiovascular checkpoint. The menopause transition can coincide with changes in cardiometabolic health, making it a good time to review blood pressure, lipids, glucose, symptoms, history, and capacity with a clinician. It is not a 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 & Heart History Check
Preserve what happened, what you remember, and what is still unclear before that part of the story disappears.
Start the pregnancy-history checkHEART RESERVE Midlife Check
Organize current numbers, family history, menopause, symptoms, testing, and physical capacity.
Start the Midlife CheckNeither check diagnoses, predicts, or scores you. Each helps you carry a clearer story into qualified care. Your answers stay on your device and are not submitted or stored.
One Thing to Prove
Match the evidence to the goal.
Progress becomes more useful when the proof matches the question. The free 7-Day HEART RESERVE Start helps you move from a private check to one focused question and a printable Conversation Card.
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 monthly 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,
Lisa Zahakos, PA-CFounder, HEART RESERVEThe book behind The Letter
The full journey, held together.
HEART RESERVE: How Women Can Build a Stronger Heart Now is a completed manuscript currently seeking publication. The free checks and The Letter make parts of the framework useful now; the book connects the whole journey.
