Hypertensive heart disease

Hypertensive heart disease refers to several different heart complications caused by high blood pressure. Medical professionals often use this term within the International Classification of Diseases (ICD) coding system. It specifically applies when a death certificate shows a causal link between hypertension and heart disease. This condition includes heart failure and other serious cardiac issues. High blood pressure is a major risk factor for other problems like atherosclerosis. This is the buildup of fats in the artery walls. Because of this link, death rates from hypertensive heart disease may not show the full impact of high blood pressure on the body.

The disease affects the heart muscle through several physical changes. One common change is left ventricular hypertrophy. This means the muscle of the heart's main pumping chamber becomes thickened. Another process is left ventricular remodeling. This is when the heart's shape changes due to the constant strain. These changes can lead to diminished coronary flow reserve. This term describes a reduced ability to increase blood flow to the heart muscle. It can also cause silent myocardial ischemia. This is a type of heart muscle damage that occurs without obvious symptoms.

Symptoms depend on whether a person has developed congestive heart failure. Many people with high blood pressure or hypertrophy have no symptoms at all. However, if heart failure occurs, many signs may appear. A person might feel intense fatigue or notice an irregular pulse. They may experience palpitations, which are feelings of a racing heart. Swelling in the feet and ankles is also common. Some people feel nausea or abdominal pain. Difficulty sleeping flat in bed is called orthopnea. Patients may also experience shortness of breath or a need to urinate more often at night.

Doctors categorize blood pressure levels to determine the stage of hypertension. A normal reading is less than 120 systolic and less than 80 diastolic. Elevated blood pressure is between 120–129 systolic and less than 80 diastolic. Stage I hypertension is defined as 130–139 systolic or 80–89 diastolic. Stage II hypertension occurs when the pressure is at least 140 systolic or 90 diastolic. Different goals exist for specific patients. For example, people with diabetes should aim for less than 130/85 mm Hg. Those with certain kidney diseases may need to stay below 125/75 mm Hg.

Hypertension affects at least 26.4% of the global population. It is a major driver of heart failure cases. In fact, hypertension precedes heart failure in 90% of all cases. It increases the risk of heart failure by two or three times. In 2004, the disease was responsible for approximately 1.0 million deaths worldwide. This accounted for about 1.7% of all global deaths. In 2013, the number of deaths rose to 1.07 million. This was a significant increase from the 630,000 deaths recorded in 1990.

There are notable differences in how this disease affects various groups. Women often have higher rates of hypertension than men. While men develop it earlier, hypertension in women is often less well controlled. This makes it a major factor in heart attacks for women. Ethnic differences are also very important. In the United States, African Americans face a higher burden of hypertensive heart disease. They experience higher rates of heart failure and higher mortality rates. This condition often develops at an earlier age in these populations.

Prevention and management are essential to reducing the risks of this disease. Lifestyle modifications can help lower the risk of cardiovascular death. These include regular aerobic exercise and weight loss. People are also advised to moderate alcohol intake and stop smoking. Some medications may be necessary to manage blood pressure or arrhythmias. Patients should be careful with certain over-the-counter medicines. Nonsteroidal anti-inflammatory drugs (NSAIDs) can make the condition worse. Decongestants containing sympathomimetics can also increase blood pressure and worsen heart failure.
