Medically, this is described as a diminished cardiac function. If an insufficient amount of blood is pumped from the heart, this is described as low cardiac output. The result of this heart weakness is that not enough oxygen is delivered to the body. This condition is called heart failure. This name sounds alarming, but in most cases the condition is treatable, though serious.</p><p>Lacking oxygen, a baby’s body will try to compensate in various ways, including:</p><ul><li>a faster heart beat</li><li>increased force of contraction</li><li>enlargement of the chambers of the heart to increase the volume of blood pumped with each beat</li><li>modified blood flow favouring the vital organs</li><li>faster breathing</li></ul><p>One consequence of poor oxygen delivery to the body can be an expansion of the volume of the heart. Essentially, the heart tries to increase the flow of blood, and therefore oxygen to the body, by expanding its size, making each pump send more blood into the system. If too much fluid is given to the premature baby or the volume of blood circulating is too high, the heart may be unable to completely pump effectively with each beat; this can create a back pressure flow which will result in water in the lungs. This is called pulmonary edema, or sometimes wet lungs.</p><p>Other possible complications of heart failure include low blood sugar, called hypoglycemia, and infection.</p><h2>Treatment of heart failure</h2><p>The most common treatment for heart failure or low cardiac output is a group of medications called inotropes, which encourage the heart to beat more strongly. Inotropes, which include dopamine, dobutamine, milrinone, and epinephrine, are administered intravenously.</p><p>Dopamine and dobutamine help the body create more norepinephrine, a natural substance that stimulates the heart to beat more strongly. The body can become tolerant to both these drugs, reducing their effectiveness over time. At low doses, dopamine works on the heart to make it pump better and increase heart rate. Higher doses cause blood vessels to constrict, increasing blood pressure.</p><p>Milrinone and dobutamine also encourage the heart to beat more strongly. However, unlike dopamine, rather than producing a higher blood pressure and increasing oxygen demands on the heart as additional effects, these medications relax the blood vessels.</p><p>The choice of a particular drug treatment will depend on the specific heart problem and the well-being of the baby.</p><h2>Complications of drug therapy</h2><p>Any inotropic agent can make the heart beat too fast causing the muscle tissue to start to tire. Inotropes can also cause an irregular heart rhythm, although this complication is rare. To avoid these complications, appropriate doses will be given and the premature baby’s heart rate will be monitored.</p><h4>More information</h4><ul><li> <a href="/Article?contentid=1586&language=English">Congestive Heart Failure </a></li><li> <a href="/Article?contentid=1801&language=English">Diagnosis of Congestive Heart Failure</a> </li></ul>https://assets.aboutkidshealth.ca/akhassets/preemie_with_hand1_BRAND-PH_EN.jpgTreatment of congestive heart failure
