Acute Myocardial Infarction (AMI) and Pregnancy

Posted on

Pregnancy acute myocardial infarction NJ lawsuitPregnancy is an extraordinary life event, filled with both anxiety and awe, as most pregnant women expect their bodies to do what some believe it has been naturally designed to do: give birth to a healthy child after about nine months. But every woman comes into pregnancy with a unique set of physiological, psychological, and emotional constitutions. What no one anticipates is that pregnancy and delivery will prove fatal for mother or baby. Sadly, pregnancy-related complications claim the lives of roughly 700 women in the United States each and every year. Worse yet, many of these deaths could have been prevented, according to the Centers for Disease Control and Prevention (CDC). Among the many life-threatening conditions about which doctors must remain acutely aware, heart failure represents one of the most common and deadly for pregnant women. A related condition known as acute myocardial infarction (AMI) is potentially fatal to both mother and baby when it occurs during pregnancy. As such, obstetricians and other physicians must know and recognize women with certain risk factors for AMI and heart failure, quickly identifying it and doing everything in their power to prevent this leading cause of maternal morbidity and mortality from taking yet another woman’s life.

Risk Factors for Acute Myocardial Infarction in Pregnancy

There are various risk factors that place women at increased risk for acute myocardial infarction during pregnancy. In particular, women 40 years and older, with hypertension, gestational diabetes, anemia, migraines, chronic kidney disease, or thrombophilia (a blood clotting disorder), are more likely to experience AMI. Lifestyle factors, such as smoking, cocaine use, and obesity likewise contribute to the onset of AMI during pregnancy, especially in the third trimester or postpartum when infection is more likely.

Pregnancy complications, such as preeclampsia, eclampsia, postpartum bleeding, transfusion, amniotic fluid embolism, and electrolyte imbalance, are also associated with the condition. In addition, family history of coronary disease should raise suspicion of AMI. In fact, women with three or more of these risk factors should be screened for possible acute myocardial infarction. Treating physicians who fail to recognize and test for such a dangerous condition in pregnant women at risk may be liable for malpractice when mother or baby dies or is injured due to a missed diagnosis.

What Causes Acute Myocardial Infarction for Pregnant Women?

Pregnancy itself triggers AMI due to increased blood volume and production of hormones like estrogen and progesterone, which affect the elasticity of the heart muscles, further increasing the risk of cardiovascular conditions. Essentially, the increased blood volume increases the blood oxygenation demand. In addition, the heart pumps more blood and works harder, increasing maternal heart rate. Plus, during labor and delivery, heart rate and blood pressure accelerate with the physical work of laboring and coping with pain, anxiety, and contractions, as each contraction produces volumes of pumping blood that strain the heart and demands more oxygen. All of these pressures affecting the heart can cause ruptures or blockages, ultimately leading to heart failure.

Immediately after birth is also a precarious time, as the blood transfer from the uterus to the general circulation and the body’s physiological changes strain the coronary vessels, risking dissection or tears in the arteries. The two most common types of AMI are spontaneous coronary dissection, or tears in the heart arteries, and atherosclerotic coronary artery disease, or narrowing of the arteries close to the heart. If delivery is several months away, a stent may be placed in the narrowed or blocked arteries to increase blood flow. Either condition is incredibly dangerous to mother and child if not detected early and treated quickly.

Considering this, it is not difficult to understand why pregnancy alone puts a woman at increased risk for heart failure. While acute myocardial infarction seldom occurs in reproductive-aged women, becoming pregnant raises the risk of AMI between 300% and 400%.

Recognizing the Signs of AMI, Diagnosis, and Treatment

Many pregnancy-related AMI cases cause death, with estimates of up to 37% resulting in fatalities among total cases. Thus, those with risk factors ought to be screened, diagnosed, and treated for AMI as soon as possible, even if a pregnant woman’s distress signs during labor seem typical. A team of medical professionals, such as obstetricians, cardiologists, and anesthesiologists, must work to improve patient outcomes by recognizing signs early. Diagnosis rests on symptoms, such as chest pain, heartburn, vomiting or dizziness. These symptoms may appear like ordinary pregnancy, labor, and delivery side effects, but doctors should be suspicious of AMI in women with several risk factors who are experiencing these symptoms. Conducting tests like Electrocardiograms (ECG’s), echocardiograms, coronary angiography (dye used to find blockages), and blood tests in women experiencing chest pain serves to narrow the diagnosis to AMI, so proper treatment may promptly follow.

Treatment aims to control the blood flow to the heart to reduce heart damage and increase survival rates for the mother and child. Medication management with aspirin, heparin (an anticoagulant to prevent clotting), and beta blockers (used to lower heart rate and blood pressure) is standard treatment for anyone with AMI. In properly timed dosing, all of these drugs can be used safely during pregnancy. Pregnant women with AMI should be treated in the ICU, preparing for emergencies for mother and newborn, especially if the baby is to be delivered early. Likewise, premature delivery risks should be anticipated. Newborns are equally at risk for complications, like breathing and feeding difficulties, so healthcare providers should be prepared to administer proper treatment to ensure that the newborn can breathe and function outside of the womb, which increases their survival chances.

Managing Birth with Acute Myocardial Infarction

When delivery is imminent, the physician must correctly choose between vaginal birth or cesarean section, considering vaginal deliveries involve less bleeding and lower infection rates, while C-sections lessen the pressure on the heart resulting from contractions and pushing. Choosing which delivery method to employ and when to deliver depends on the viability of the fetus and the status of the mother’s health. These and many other decisions along the pregnancy, labor, and delivery process are critical to managing a safe childbirth.
